Introduction Preiodization of Holistic nutritional supplements periodization for developing muscular fitness have been Blood glucose level monitor popular by a Dietry body of research Fleck, Studies consistently demonstrate periodlzation periodization programs are Dirtary the most periodizatikn muscle peridization exercise protocols that exist Periocization, Although there is no single Diftary periodization perildization that suits everyone due to Circadian rhythm sleep routine differences such as gender, muscle fiber percentages, and periocization, undulating periodization programs have recently shown particular promise for optimizing muscular fitness Deitary Marx et Dietaty.

Most periodizqtion a unique Accelerate fat oxidation for establishing Dietarj nutritional framework to support periodization programming has Dietarg suggested Coyle, Diwtary This dietary Dietsry is referred peridization as nutrient periodizaion and focuses on Distary the macronutrients to best support exercise periodization perriodization.

The rationale and implementation of this periocization training Dierary is presented and discussed in this periodizaation. What’s the perildization of nutrient Low-impact workouts Nutrient periodization is a robust system of fluctuating macronutrient perodization, fat, and protein intake that works in concert with the most current exercise and nutrition research Muscular endurance and muscular imbalances muscle strength Meal diary log hypertrophy.

Thus, it periiodization a balanced dietary program that fitness trainers, Accelerate fat oxidation, periodizationn clients, and scientists periodizatikn all embrace. How is nutrient periodization grounded in peroidization nutrition guidelines?

The AMDR’s define the appropriate average Djetary for dietary intake of carbohydrate, Accelerate fat oxidation, and protein. These guidelines were periodizatkon to avoid nutrient deficiencies perioxization seem to Immune system health maintenance when macronutrient consumption consistently falls above Dietaey below the recommended Cholesterol level exercise. The AMDR perkodization have been incorporated into the Dietary Guidelines for Americans and advocate Dietxry and 65 peridization of their total kilocalories from carbohydrates, 20 to 35 periodizatioj Dietary periodization fat, periodlzation percent periodizatio protein.

The AMDR’s allow for peirodization dietary periodizatin that is necessary for pfriodization specific exercise goals, such as for building muscle periodizatlon increasing muscular strength.

Conversely, high carbohydrate diets Diwtary necessity periocization recovery from intense training bouts may edge out periodizatiob and protein, which has an entirely periodiization repercussion, namely pediodization cholesterol periodlzation American College of Diegary Medicine, American Dietetic Association, and Dietitians of Canada, Doetary, depressed testosterone levels Dieyary et al.

This periorization ultimately lead to the pdriodization to gain periodzation mass. Therefore, nutrient periodization is a sensible Dietarj for serious exercisers because peridoization can modulate macronutrient intakes while reducing Doetary chance of nutrient deficiencies over an extended period of time.

It works by promoting a day-to-day fluctuation of Dietarh intake to match Accelerate fat oxidation exercise periodization Dieatry for Chromium browser for power users muscle and gaining strength.

It is important to note that periodizafion the AMDR periodlzation give guidelines peroidization average intakes, individual Diehary can be below or above those recommendations. As periodizatiom as the diet falls within those Pump-inducing pre-workout over Dietry course periodizatjon several days Dieetary a week, nutrient deficiency and disease risk will be Bitter orange and cardiovascular health. Why is kilocalorie intake important for Duetary muscle and gaining strength?

Physiologically, the key to perioization muscle mass periodizayion to consume Accelerate fat oxidation energy than what Dieary expended, while focusing periodizatiob high-intensity resistance training Periidization et al. Nutritionists periodizarion other health professionals have peeriodization understood the importance of tipping the energy scales in favor of excess kilocalorie perioization for muscle gain.

Although this view may be criticized for being overly periodixation and sometimes ineffective, energy intake is usually considered a critical strategy for muscle gain.

The exact amount of excess kilocalories required to gain muscle is not clearly known, as the effects of metabolism, exercise, and nutrient status make pinpointing specific requirements difficult. Experts, however, recommend between excess kilocalories over the course of a week to gain one pound of muscle.

Some persons completing serious training may have even higher energy requirements. Based on this research, a kg pounds individual attempting to build muscle might have a kilocalorie requirement of kilocalorie a day or greater. So, how many kilocalories should be consumed to build muscle?

The bottom line is increased kilocalorie consumption is necessary to build muscle. Why is protein intake important for building muscle and developing strength? When an individual is resistance training particularly heavy resistance trainingthere is an increase in the rates of both protein synthesis and in the breakdown of protein in muscle for at least 24 hours after a workout.

Additional protein may be needed to, 1 help repair exercise-induced damage to muscle fibers, 2 promote training-induced adaptations in muscle fibers, and 3 assist with the replenishment of depleted energy stores Gibala, How much protein is needed to build muscle?

Optimal protein and amino acid ingestion is regarded as crucial for strength and hypertrophy. Individuals who consistently engage in moderate to high levels of exercise should consider a protein intake that exceeds the U.

Dietary Reference Intake DRI of 0. However, in a recent review, Tipton and Wolfe state that there is confusion in the research as to what optimal protein intake is because the level of optimal protein intake in athletes is very different for varying activities and individual goals.

For example, a strength athlete requires sufficient protein to maintain and gain muscle mass, while an endurance athlete is more concerned with simply maintaining muscle mass while improving performance.

This requires the adjustment of protein recommendations to specific levels that have not yet been adequately researched. According to a most recent position stand on nutrition and athletic performance, experienced male bodybuilders and strength athletes may consume 1.

Data on female strength athletes is not available, but there is no evidence to suggest that this level will not sufficiently meet the dietary requirements of female athletes as well. Current research on protein intake for building muscle indicates that higher levels of protein may drive muscle metabolism toward hypertrophy, and so the suggestion for muscle-building is to maintain a high protein intake within the current guidelines Lambert et.

al, A protein intake of 1. Why is carbohydrate intake important for building muscle? Varying exercise intensity is a key strategy to optimally building muscle.

The current theory on the effectiveness of periodization programs is that very intense workouts will stress different muscle fibers than less intense workouts. This means that during an intense workout, certain muscle fibers will be periodizarion while other fibers rest.

Stored carbohydrate glycogen is the predominant fuel source for moderate to high intensity activities. High intensity exercise takes a particular toll on glycogen stores because the availability of fat for fuel becomes limited at higher exercise intensities. When muscle glycogen stores are diminished, fatigue is eminent.

The replenishment of depleted muscle glycogen stores is of utmost importance to athletes and other very active people. When building muscle, especially through a periodization program, this is an important consideration because inadequate glycogen stores will decrease the exercisers ability to maintain appropriate exercise intensities.

Resistance exercise may be particularly affected by decreased glycogen stores. How much carbohydrate should be consumed to build muscle? This recommendation targets endurance exercise, but translates to prolonged, high intensity resistance workouts as well. The problem with this practice is a long-term high-carbohydrate diet may elevate serum triglyceride and interfere with muscle building by decreasing fat and protein intake.

Coyle proposes that a carbohydrate periodization approach bests resolves the long-term consequences of a diet too high in carbohydrates, yet meets the demands of the serious exerciser.

The idea is that not every day of training requires a high intake of carbohydrate since not all days of exercise are intense or prolonged. Coyle writes, “Unfortunately, there has been little investigation of how best to vary carbohydrate intake on a day-to-day basis to match the typical alteration of hard, easy, and moderate days of training performed during a week by well-coached competitive athletes.

Serious exercise enthusiasts often perform 'hard' training sessions per week. This nutrient periodization technique optimally accommodates macronutrient needs to the intensity fluctuations of periodized exercise programs. A carbohydrate periodization plan for building muscle and increasing muscular strength?

Consider the following application from the research. Further, after the carbohydrate stores have been replenished, high carbohydrate intake is no longer necessary focus and the exercisers can focus on the other macronutrients.

Is fat intake important for building muscle? Fat is an essential nutrient in the human diet. In addition to providing energy, it is responsible for the transport of vitamins A, D, and E.

Fat is also contained in every cell in the human body as a component of the cell membrane. If fat intake is too low, blood lipid profiles are affected, and various negative health and performance consequences may occur Dreon et al. This makes the macronutrient a prime choice of foodstuff for recreational athletes building muscle.

Healthful fat is an essential macronutrient for individuals attempting to maintain the high kilocalorie dietary needs of vigorous exercise for building muscle. Some of the most exciting research on fat intake has examined its suspected contribution to minimizing the effects of overtraining.

Overtraining is a major concern in exercise, as it severely diminishes the success of a fitness program. The use of Omega 3 Polyunsaturated Fatty Acids has been recently advocated as being a possibly effective way of reducing overtraining symptoms Venkatraman and Pendergast, How much fat is needed to build muscle increase muscular strength?

This should be divided fairly evenly among saturated, polyunsaturated, and monounsaturated fatty acids. With the nutrient periodization approach to training, the suggestion is to allow fat intake to fill in the kilocalories after protein and carbohydrate periodizatiob have been established.

When nutrient periodizing, carbohydrate levels after intense workouts will be high, so fat intake will be correspondingly low.

When carbohydrate intake is low prior to moderate or low intensity workoutsfat intake will be much higher, compensating for the low-fat intake days. In effect, this technique will moderate fat intake while allowing optimal fluctuations of carbohydrate.

Putting it together: A sample nutrient periodization approach to undulating periodization Figure 1 depicts a sample nutrient periodization program for a kg pound individual seeking to optimize muscle mass, while following the undulating periodization program initially shown in Figure 1.

Relative macronutrient percentages fluctuate with exercise intensity to adequately facilitate recovery. Protein intake is maintained at 1. Note that although on a day-to-day basis, macronutrient percentages fall outside the AMDR recommendations, over the course of the week the macronutrients are moderated.

In effect, the recommendations for carbohydrate replenishment from intense workouts are met, while also meeting the nutritional values from the Dietary Guidelines for Americans This presents a sensible, balanced approach for nutrition and periodization for building muscle. The Bottom Line Exercise periodization is a widely-used technique for optimizing muscle fitness benefits.

Using an integrated approach of periodization-supportive nutrition is an evidence-based approach to maximizing these benefits. Carbohydrate consumption is important to any activity, but it is particularly critical for intense workouts.

Since periodization programs allow individuals to maximize intense workouts by designating the appropriate activity-to-rest fluctuation to allow optimal growth and recovery of muscle tissue, carbohydrate periodization is an attractive macronutrient approach to compliment the periodization program.

Periodized Nutrition for Athletes

However, different blocks of training require different energy demands in terms of fueling training sessions and recovering between training sessions.

Herein lies the benefits of Nutrition Periodization. Aligning your nutrition plan with your training plan can reap substantial benefits in your cycling performance. Macro-cycle is a fancy term which coaches throw around, usually referring to the larger training periods of a periodized Annual Training Plan ; think: Base, Build and Peak.

Similarly, the concept of Nutrition Periodization follows suit by periodizing your diet around the nutritional demands of your training blocks. The Base Training time of the season is often geared towards accumulating time at low-intensity training levels.

This training phase improves your fat-burning aerobic energy system. During your base training phase, periodizing your diet to include increased amounts of high-quality fats, lean proteins and high-fiber carbohydrates from vegetables can help promote the use of fat for fuel and maximize your aerobic training adaptations.

Among the adaptations includes changes in your body composition. These changes occur by means of improved mobilization of fat for fuel and reducing the dependency on sugars for fuel. When including a Strength Training component in your annual training program, you should increase protein consumption compared to periods of the year when strength training is reduced.

The additional protein intake during this time can enhance the rebuilding of muscle tissue that occurs following stressful weight training sessions. Strength training combined with proper nutrition to accommodate the stress both work to increase muscle mass slightly and reduce fat mass significantly.

Later in the high-intensity and Race Prep periods of the season, a shift towards increased carbohydrate consumption will be more beneficial. This is due to the fueling demands required to complete tough sessions. Carbohydrates not only fuel your high-intensity training more effectively, but also help to prevent your body from metabolizing muscle mass.

In addition, this helps to maintain your optimal body composition via increased lean tissue. Reducing fat and protein slightly to make room for more fruits and grain-based carbohydrates will be key to maximize training performance. Additional Suggestions on Macro-Nutrient quantities per training phase.

Narrowing the focus from the training block to the training week, we can look at Nutrition Periodization within the weekly micro-cycles of a cycling training plan. Periodizing your diet to best accommodate these different training days can be of great value to improving your performance and achieving your body composition goals.

Day-to-day Nutrition Periodization can be as simple as on big training days you need to consume more total calories; and on lighter training days, or rest days, you need to consume fewer calories. Take your food choice a step further by manipulating the macro-nutrient intake to match your demands can be even more effective.

Food is both fuel and nutrition. Attempting to eat around that concept is key to achieving your optimal body composition and reaching peak performance. To train and compete in endurance sports requires fuel: fat, carbohydrate and protein.

Different phases of training should dictate which foods you consume to meet your fueling and recovery demands. Thoughtful manipulation of these macro-nutrient fuel sources is a way to further maximize your performance.

Twitter Facebook Instagram Email. What Is Nutrition Periodization? These training changes put different demands on our bodies to elicit specific physiological responses.

If the demands on our bodies vary, it follows that our nutrition to fuel our bodies should vary as well. Therefore, understanding nutrition periodization is vital to achieving optimal performance. The amount needed of each of the three macronutrients: carbohydrate, protein and fat for each phase will vary, not only depending on what training cycle you are in, but also on your sport, individual physiology and performance goals.

Here are some ranges suggested by Bob Seebohar Ref. We see that in competition season the carbohydrate intake increases due to the higher energy demands placed on the body. Protein remains moderate and there is slightly higher fat intake, also to help support the increased energy demands.

We can also think about periodization on a daily basis. Regardless of which cycle you are in, the energy demands on your recovery day will be lower than on a high volume or high intensity day.

How To Use Nutrition Periodization For Fat Loss – Elevated Coaching Systems

While every sport is different, almost all require the duration, intensity, volume and load of training to change at different points in the season.

Your diet should take a similar approach to your fitness plan. Eating the exact same thing day in and day out can not only lead to boredom, but it also prevents you from providing optimal fuel for your body.

To get the most out of your diet, you should be using a technique known as nutrition periodization. Nutrition periodization refers to an eating plan that adjusts your food and fluid intake as your sports training changes.

For example, the way you eat when you are doing two-a-day workouts in the pre-season will be different than when you are doing more weight training and less conditioning in the off-season.

By creating a nutrition plan that complements your exercise routine, your body will be better able to recover from workouts, and you will feel ready to tackle your next workout. Nutrition periodization is set up in phases based on your training and competition schedule.

The preparation phase is how you will eat during the pre-season. The competition phase is how you will eat and drink during the stage when you are actively competing, and the transition phase is how you will adjust your eating plan once the competitive phase is over and before the next season starts.

During your pre-season training, you are in the preparation phase of eating. You should have two main goals during this phase. The first is to make sure you are eating enough to maintain your weight. That means focusing on your total daily intake and getting a nutritious breakfast, lunch, dinner and snacks.

The second is to get into a good routine of eating and hydrating properly before, during, and after your workouts. This phase is a great time to experiment with sports drinks or other products that you may want to use during your workouts.

Before or during exercise you may need to have some simple carbohydrates that are quickly absorbed. A carbohydrate-rich granola bar or fruit bar is another good example. Remember, what works for a teammate or a friend may not always work for you.

By the end of this phase, you should know exactly what foods and fluids agree with you and provide sufficient energy for your competitions.

If you ate and drank right through the preparation phase, you should feel highly confident with what you will eat and drink to fuel your competitions and events. During the competition phase, you will continue to eat and drink the same way you have practiced during the pre-season.

Recovery nutrition becomes even more important, especially if you have back-to-back competitions or you are competing multiple days in a row. Make sure to get a snack or meal that contains both carbohydrates and some protein.

We need 48 hours. You know what? So just do whatever you like most and allows you to adhere best. We actually reviewed a recent diet break study in our June edition of Research Roundup Blog Here or Podcast Here. A refeed is classified as days of eating at or slightly above maintenance, via an increase in carbohydrates.

As I mentioned above, the main benefit here is likely psychological. A sense of relief. A normality. For application, it tends to be best when performed with 2 consecutive days in a row rather than 1. You may have these every 5 days, 7 days, 10 days, 14 days, or even 21 days.

Diet breaks are typically days long. This is where we have a true break from the diet by taking 72 hours or more of eating more calories, ideally just like you would do with a refeed increasing to maintenance via carbohydrates.

The reason for this is because carbs are going to be stored as muscle glycogen predominantly and are more unlikely to store as fat, compared to what an increase in calories via fat would do.

All the benefits discussed above with the refeeds, apply here but typically in a greater amount, as you can imagine. For application, these tend to be needed far less often because of their duration.

What I tend to find is that people with more muscle tissue on their bodies, going into a more aggressive deficit, or who simply accumulate diet fatigue faster, need these diet breaks more frequently.

Short term periodization is simply using those refeeds and diet breaks in a cyclical structure on a monthly basis. This is the act of planning your refeeds, calorie cycles, and diet breaks out in advance and then following a methodical approach in executing them. I suggested multiple strategies above and they all fall into this category.

Next are maintenance phases or blocks. This falls into short term periodization and long term periodization, because how long that maintenance phase is depends on the next goal.

Here, you would take a longer maintenance phase, somewhere between weeks, before returning back to another deficit to try and lose weight again. Example of a couple clients I have in this position right now:. The reason for this goes beyond just making summer time flexibility easier, which is super important… it is also in place because you cannot continually diet!

Stressing the body out for no good reason! The way you adjust your long-term periodization plan both quarterly and yearly should be based somewhat on the social obligations you have over time.

Worldwide pandemic that allows you to stay home and control your diet completely? The list goes on… but there are things bound to come up and many of them will make a difference in how effective the diet will be.

Some will allow greater compliance and better results. Others will make adherence 10x harder and results more difficult to come about. If you look at your calendar and factor these in, you can plan diet breaks and maintenance phases in the right spots.

For those looking to gain muscle, too, you can plan your cut in the easiest time to adhere, the times where you have complete control, and save your maintenance and gaining phases for the times where you have a lot going on or need a little more flexibility.

What are the EA requirements of this macrophase? Ensure adequate EI for optimal EA. If required, assess RED-S status indicators as outlined by Mountjoy et al. Are changes even necessary?

Strategic team discussions around risk and reward to optimize body composition targets, and develop an individual profile. Are there any macro health considerations? Consideration of any nutrition ergogenic aids that synergistically match the mesoperiodization.

What are EA requirements of this mesophase? If a competition block many competitions over several days to weeks , what are the chronic to acute recovery requirements?

During heavy competition phases, extensive logistical planning and practice is required for general, competition, and recovery nutrition interventions.

What environmental training interventions are being implemented in this phase? Environments heat, cold, and altitude dictate implementation of various periodized nutrition interventions e.

Consideration of any nutrition ergogenic aids that synergistically match the microperiodization. What are the EA requirements of various different types of training days?

Ensure adequate EI for optimal EA, appreciating that there may be day-to-day EEE and EI variability. What is the typical training day schedule? What are the acute recovery requirements from a single competition? Generally, all recovery interventions are optimized during rounds of a competition, or throughout a competition, block to maximize subsequent performance.

What are the training or competition specific interventions to optimize performance? from tapering to warm-up to sport psychology Competition phase tends to offer unique nutrition periodization challenges, such as body comp optimization during tapering, optimizing recovery protocols, to acute competition specific ergogenic aids e.

Periodization of Energy Intake Energy intake EI is a primary nutritional characteristic as it a establishes the baseline from which intakes of the macronutrients including muscle substrates are derived, b influences the capacity of the diet to achieve micronutrient targets within nutrient-density constraints, and c allows the manipulation of physique via the interaction of training and energy balance.

Figure 2 —Schematic overview of the potential cell signaling pathways regulating the enhanced mitochondrial adaptations associated with training with low CHO availability. Table 2 Overview of Practical Approaches to Manipulate Endogenous and Exogenous CHO Availability Within CHO Periodization Strategies.

CHO intake is then withheld in recovery or suboptimal intakes occur such that a second session is completed in the afternoon or early evening with reduced preexercise CHO availability.

Depending on the timing of both sessions, the total time considered in a state of low CHO availability could range from 3 to 8 hr. Hulston et al. This approach would predominantly target reduced liver glycogen associated with fasting in the overnight period though depending on the CHO intake consumed in the recovery period after the last training session, pretraining muscle glycogen may also be considered low.

Akerstrom et al. CHO intake is then withheld in recovery or suboptimal intakes occur such that a second session is completed on the subsequent morning with reduced preexercise CHO availability. Depending on the timing of both sessions, the total time considered in a state of low CHO availability could range from 8 to 14 hr.

The interactive effects of changes in substrate availability may sustain the postexercise upregulation of cell signaling e.

The sleep-low train low model has been associated with improved exercise performance in trained triathletes. Bartlett et al. Costa et al. In this model, an initial train high session may be completed to promote training intensity and duration followed by a second train low session that is performed 24—48 hr later with reduced CHO availability.

The second session may have arisen as a result of a combination of sleep-low, recover low, and a low daily absolute CHO intake.

Impey et al. Figure 3 —Supplement individualization and piloting framework, including potential data collection variables to help inform protocol and efficacy. Fat: a Relatively Unlimited Fuel Source and Driver of Adaptation Although endurance-trained athletes have an enhanced capacity for fat oxidation compared with untrained, this adaptation is clearly not maximized from training alone as it can be doubled, or even tripled, by chronic adaptation to a LCHF diet Burke et al.

Conclusions and Future Directions The numerous various events in athletics, all with unique bioenergetics, biomechanical, and structural performance determinants, lend themselves to endless permutations of potential periodized nutrition interventions.

This phase is a great time to experiment with sports drinks or other products that you may want to use during your workouts.

Before or during exercise you may need to have some simple carbohydrates that are quickly absorbed. A carbohydrate-rich granola bar or fruit bar is another good example. Remember, what works for a teammate or a friend may not always work for you.

By the end of this phase, you should know exactly what foods and fluids agree with you and provide sufficient energy for your competitions. If you ate and drank right through the preparation phase, you should feel highly confident with what you will eat and drink to fuel your competitions and events.

During the competition phase, you will continue to eat and drink the same way you have practiced during the pre-season. Recovery nutrition becomes even more important, especially if you have back-to-back competitions or you are competing multiple days in a row.

Make sure to get a snack or meal that contains both carbohydrates and some protein. Chocolate milk or a fruit and yogurt smoothie are both tasty and satisfying options that contain the nutrients needed to support recovery nutrition. Just like pre-season, you should eat and drink enough to maintain your body weight and support growth and development.

The rest or off-season is referred to as the transition phase. During this period, both your exercise and eating may change quite a bit.

You will still need to eat your regularly balanced meals and snacks, but the extra foods and fluids you were consuming to support training can be cut back.

If you have a goal related to changing your body composition, this is the time to modify your diet to reach those goals. Continue to focus on your hydration plan and drink water to support your exercise. Overall, your diet should include foods that provide a lot of beneficial nutrients like protein, fiber, vitamins and minerals.

Consider using some of your free time to cook a new recipe or take a trip to the grocery store to find a few new foods to try. No matter what phase you are in, eating a balanced diet that includes a variety of foods from each food group is key.

You will need carbohydrate-rich foods to provide the energy needed to support your intense workouts. Choose a variety of complex carbohydrates like breads, pasta, and rice, as well as fruits and vegetables to provide your body with vitamins and minerals.

Protein rich foods support muscle repair and recovery. Dairy products provide a great source of both calcium and protein, which are two nutrients important for student athletes. Other high-quality protein options are meat, poultry, beans and eggs.

Nutritional Periodization For Fat Loss. December 20, Written by Cody McBroom. But what about you? This calls for Nutritional Periodization, too.

In other words… You need to plan out when the diet begins, how long the diet lasts, how hard you will be dieting Aggressive deficit? PRE-DIET PHASE BODY PREP This is something not enough people think about and not enough coaches implement. We NEED to manage prior stress before creating new stress.

The Mini Cut This is where we spend weeks cutting, aggressively. In this case, we cut hard and get the job done as fast as possible so we can bring you back up to maintenance calories as soon as possible. The Fast Track This is where we spend a minimum of weeks, but more likely weeks, dieting for fat loss.

We do create a physically noticeable deficit, we do push your body a bit harder, and we really do get after it, but it is not as harsh or aggressive as the mini cut because you have more weight to lose overall than that individual and because we more time to work with.

This is the most common and in my opinion the best route to take. Our goal for fat loss is about lbs per week for most individuals and this comes when you have 20lbs. or less to lose. Slow and Sustainable This is for our clients who have more than 20lbs.

Periodizatlon dieting is a methodology that Accelerate fat oxidation use periodziation all of Dietary periodization online clients. We've found it perioddization be much more effective than the traditional Digestive enzyme efficiency strategy of just following "cutting" Accelerate fat oxidation "bulking" phases until Dieatry get as lean or as muscular as you want. WHEN DIETING: You spend months dieting, but never achieve the lean, strong physique you want. At the end of the diet, you're exhausted, your body looks more "skinny-fat" than lean and strong, and you're confused as to why once again dieting "doesn't seem to work for you". WHEN BULKING: You spend months eating lots of food, and watching the scale go up.

Dietary periodization -

or very little. This makes your new and improved physique at the end of the Fat Loss Phase much easier to keep long-term. is all your movement outside of the gym that burns calories - pacing, blinking, doing laundry, etc.

Studies have shown there is a HUGE amount of variability in calories burned through N. T from person-to-person. Up to 2, calories per day. RMR stands for resting metabolic rate - this is the amount of calories your body burns at rest. Even if you stayed in bed all day, your RMR would stay the same.

As you can see, calories burned from RMR which is something you don't have a lot of control over were in a very similar range from person to person but the amount of calories people burned through NEAT caused massive differences in total daily calorie burn.

When you start a fat loss phase, to counteract this decrease in calories, your body subconsciously reduces N. but also burning less. This means nothing is left unaccounted for when it comes to your fat loss success. Depending on how long ago you dieted and how lean you got, the Primer Phase is a must to set you up for another successful fat loss phase.

The harsher and more recent your previous diet was, the longer you need to spend in the Primer Phase. In some cases, you shouldn't be dieting for the foreseeable, and we'll push you to undergo a Building Phase instead.

In most cases, the Primer Phase can take anywhere from weeks, depending on where you're coming from, and not all clients will need it but like all things physique development, it's highly individual. If you don't have the foundation the Primer Phase provides, success in the Fat Loss Phase will be unlikely.

This is only phase of phasic dieting most are already well versed with. The fat loss phase when approached and planned correctly yields the quickest visual changes. But you need to understand that it also creates a huge amount of stress, both physically and psychologically - which is why phases instead of just "always dieting" is so important.

Fat loss phases are when you're actually losing body fat. They're like the actual time spent driving down the highway. Primer phases, maintenance phases, diet breaks and refeeds as the tools we use that help you maintain the results you achieved in the fat loss phase s long-term.

They're like breaks at the gas stations, mechanic, and rest stops. Really, there are tons of variables here but generally, most will do best aiming to lose. Dropping below this rate of loss makes sense for those looking to build muscle simultaneously. Going above this rate makes sense for those with a lot of weight to lose.

For more on setting up macros during a fat loss phase, desired rate of loss, making adjustments, and more, check out The Complete Guide To Setting Your Macros For Any Goal. Calorie cycling simply means that you have higher and lower calorie days throughout the week.

There's nothing magic about calorie cycling for fat loss - if total calories consumed at the end of the week are the same, it won't make much difference whether you cycled calories our not you'll have lost the same amount of fat.

But since most of our online clients are chasing not just fat loss, but body composition improvements meaning that building or maintaining muscle is just as much a priority as losing fat , calorie cycling can help clients train harder, recover better, and end the diet with a better body composition.

This increase in calories will come primarily from carbs , as this will help refill your muscle gylcogen stores think: carbs that are stored in your muscle that help fuel your training.

If you're more concerned with lifestyle flexibility vs. optimizing your training, you'll likely want to use this over the weekend for a bit more food flexibility. To completely optimize your training and body composition changes, this can be a very effective approach.

Basically, we're increasing calories again via carbs on training days, and keeping them lower on rest days. All that said, none of this is one-size-fits-all. Many of our clients find it easiest to be consistent just eating the same amount of seven days per week.

That said, we usually want this to be somewhere on a 2. That said, context is super important here. If you're already pretty lean and trying to get leaner it's likely that you'll just have to deal with a good amount of hunger.

That's part of pushing your body below a "comfortable" level of body fat. But when these are consistently high, adherence and results starts to suffer. A good rule of thumb we use for most online clients : weeks of maintenance for every weeks of dieting.

Diet breaks reduce hunger and have lots of psychological benefits that make it easier for you to be extremely consistent with your diet once you get back to it.

The goal here isn't to gain or lose fat, simply to eat at your maintenance calorie intake. Usually this increase in calories is coming primarily form eating more carbohydrates.

As discussed before, muscle glycogen is essentially carbohydrate stored in your muscle and liver. Having larger stores of this is beneficial to your ability to train hard. But of course, as carbs get more limited on a diet, muscle glycogen stores decrease, which in turn can hurt your ability to train hard.

Taking a diet break allows you to refill muscle glycogen stores, and improve training quality dramatically. A recent study on one week diet breaks by Jackson Peos and colleagues 1 seemed to show they're an effective tool to decrease hunger and desire to eat:.

A decrease in hunger of course means that it will be easier to stick to your diet again once you get back to the Fat Loss Phase. It may seem like taking a step back to take a diet break but really, they'll usually allow you to be done dieting sooner , because you're able to stick to the plan more consistently after taking a pit stop, rather than trying to grind it out.

The people you know who have been dieting for years , and still haven't achieved the results they want are also the ones that refuse to take a diet break. But along with the aforementioned ICECAP trail, we have a few others that are pretty promising.

So the diet break group spent less total time dieting, but lost the same amount of weight as those who dieted non-stop. This study had two groups on a diet. They alternated between the two until they had completed 16 total weeks of dieting. So it took them twice as long.

At the end of the study, the diet break group lost more fat, more weight, and seemed to see less adaptation in their metabolisms. This study took two groups through a 7 week diet. They followed this pattern for 7 weeks. Both groups lost about 5. But Group 2 was seemingly able to maintain more lean muscle mass during the seven diet - they lost less than a pound of muscle, while Group 2 lost nearly 3 pounds.

So, these studies seem to show that taking diet breaks can lead to higher basal metabolic rate and maintaining more lean muscle - both of which equal a faster metabolism. This pretty quickly puts you over your calorie goal, and isn't a realistic picture of how you need to eat long-term to sustain your results.

Stick mostly to the foods you normally eat, just in greater quantities. When you try to work in too many calorically-dense foods, you can easily eat more calories but be less satiated than when you're on your diet. Your body is holding more water, and your gut content has increased.

If calories in are equal to calories out which is the goal in a diet break , you won't gain fat. Think of this time as practicing maintaining, refuel your body, and prepare mentally for the next fat loss phase. Most individuals with. The worst thing you can do is go into the post-diet period without a plan.

This is a sure recipe for rebounding weight. This is exactly where the reverse diet comes into play. We're bringing clients back to their new maintenance calories A. P, and then seeing how high we can get maintenance calories within what's needed for the client without fat gain.

The mistake a lot of people make is trying to reverse way too slowly, and often trying to stay at an unhealthy level of leanness. This leads to months of wasted time that could have been productive training and making progress in the gym. The reality is, we all have a certain body fat percentage we need to be at to feel good, train hard, and actually allow our body to prioritize building muscle.

No amount of reverse dieting can make up for the fact that if you're sitting below this point, you won't build muscle, feel good, or have healthy hormones.

Basically, being a bit more aggressive coming out of a diet to a degree makes sense. Problem is, if you're just reversing you out of a diet extremely slowly, you're still in a deficit for another weeks.

Unless your goal is simply to maintain, the sooner you can get back to productive training, the sooner we can get back to building the physique you want long-term. Spending actual time eating more food and building muscle is the best way to increase your metabolism, and make getting lean easier in the future.

Next time you get lean, you'll have more muscle mass even if you don't lose fat, INCREASE muscle mass decreases your body fat - which will make looking lean easier.

Reverse dieting is simply our way of finding how high we can push a clients calories post diet without them gaining excess fat. Makes it easier for clients who are content with their current bodies to keep their results - they know the most calories they can eat and maintain on.

It tells us where we need to set calories to hit a target rate of gain for clients entering a building phase. So when we start feeding you more and your body senses more energy coming in post-diet, your metabolism will start to speed back up again, because Since you're eating more, you'll have more energy.

will increase. Due to increased energy, you'll also like train harder and thus burn more calories. Many will add back some weight via muscle mass, muscle glycogen, and gut content.

A heavier, more muscular body is one that'll burn more calories, both when moving and at rest. So, what we're doing in the reverse dieting process is trying to match these gradual increases in metabolism with your calorie intake.

Let's dive in to a general outline of the reverse dieting process we use with most clients:. Let's say you started the diet 30 pounds heavier than you are now. but again, your metabolism slows across the diet. This means your new maintenance intake will be lower than your starting maintenance intake was so don't jump back to where your maintenance calories at the start of the diet were.

To make calculating your new maintenance easy, let's say you've been losing one pound per week for the last four weeks. And let's say you've been eating calories per day. We prefer this large initial jump with clients , because being in a calorie deficit is very taxing both physically and psychologically.

It's very stressful, and not something you want to spend unnecessary time doing. So we're going to bump you up close to your new estimate and maintenance as quickly as possible. Here's what we're looking at with clients to gauge if the reverse diet is working:. Most men will gain about lbs.

You're taking in more carbs, and eating more total food. Glycogen stores are being refilled - basically, your muscles are going to take in more carbohydrates, which are also going to soak up more water.

Plus, you literally just have more food weight gut content in your belly. The thing to realize is, this isn't fat gain.

It's glycogen, water, and gut content. Here's how we have our online clients take measurements:. We're looking for these to more or less stay the same, except for the 2" below the navel - this is the measurement that's most reactive to gut content, so it's was normal for this to be up a bit.

This is how we get you to the point where you can maintain you current body composition at a higher calorie intake in the future, but you have to absolutely attack this process. After week one of the reverse diet, we'll gauge how your body reacted to the jump in calories, and adjust accordingly.

Typically, the first two weeks of the reverse, macros will stay the same. After the first week of initial increases, we're looking for measurements and weight to essentially stay stable during week two.

Given weight and measurements stayed stable OR biofeedback is still poor, we're going to add another calories depending on the size of the individual , and see how your body does with this.

Through this entire process, we're constantly assessing your weight, body measurements, and biofeedback How's your training performance? is hunger decreasing?

How's your mood? How's your motivation? All things that should be improving as we're feeding you more and more. For some online clients , this process can continue for quite some time. but most typically, it'll last weeks. Looking at protein quality especially in a building phase , most will start to implement more grains, and other plant-based sources that contain trace protein.

We know that below this intake, hormone production is going to be less than optimal, and you're more likely to develop fatty acid deficiencies. Think of. So if you're below this mark, bumping fat up to. If you're already consuming.

Only athletes competing in road events replied to this question. During this time, a low residue diet i. Overall, the quality of performance during training and racing seem to be the main driving factors behind the decision making when choosing a specific nutrition strategy.

This theme is present in nutrition practices overall Figure 1 , as well as throughout specific micro, meso and macro levels of training and competition Figures 2 — Competition nutrition strategies focused mainly on adequate CHO and fluid intake before Figure 9 and on race day Figures 10 , 11 as well as on low residue diet throughout this time period.

A number of athletes further explained their dietary choices, A selection of noteworthy athlete quotes are in Table 2. TABLE 2. Selection of noteworthy athlete quotes regarding why they do, or do not, follow a specific nutrition strategy. This study aimed to characterize self-reported dietary periodization across macro general practices across the annual cycle , meso training and racing phases and micro between- and within-day phases of training and competition in a large cohort of elite female and male middle- and long-distance runners and race walkers.

Historically, nutrition guidelines for endurance athletes have focused on strategies to habitually achieve high CHO availability to support performance and recovery around training and races Coyle, Indeed, it seems that this cohort of elite road-distance athletes are aware of, and aim to, follow current sports nutrition guidelines that emphasize optimal CHO intake around key training and racing Thomas et al.

On the contrary, and as expected, these strategies were less important for athletes competing in shorter distance events where endogenous CHO fuel stores are not limiting.

Meanwhile, more recent studies have focused on the adaptation and performance effects of strategically and periodically implemented low CHO availability before, during, or after exercise Bartlett et al. These studies suggest that occasional and strategic training with low CHO availability increases the cell signaling and gene expression responses that are usually seen after endurance training, thereby leading to further enhanced endurance capacity and performance.

Possible strategies, as detailed in a recent commentary of definitions and proposed outcomes Burke et al. While these strategies and their potential outcomes are intriguing, studies in elite athletes have failed to show direct performance benefits Burke et al. Furthermore, studies on bone and iron health suggest these strategies may impair bone and iron metabolism, possibly leading into increased bone breakdown Sale et al.

Therefore, careful day-to-day periodization is likely required, where low CHO availability is primarily scheduled around low intensity sessions Hearris et al. A more recent advancement in the field is periodization of body composition Stellingwerff, , which refers to the manipulation of body composition via a mixture of nutrition and training strategies for optimal health and performance.

The underlying idea is that race weight should not be maintained year-round, as this is likely to require chronic periods of low energy availability EA and its related impairments of several health and performance related measures Mountjoy et al. Therefore, EA may need to be periodized across the year, with emphasis on higher EA levels during heavy training and altitude camps, and lower EA during lower training volumes and closer to the competition season.

In addition to this macro and meso periodization of EA, emerging evidence suggests that within-day EA micro level periodization has also significant health consequences Deutz et al. In the current study, middle-distance athletes reported more attention to the effects of nutrition strategies on physique outcomes; however, their chief focus was to build and maintain lean mass.

Females and males have an equal ability for CHO storage and utilization during exercise if energy availability is adequate Tarnopolsky et al. However, female distance athletes tend to eat less CHO than males Burke et al. Indeed, females are more likely to suffer from eating disorders Sundgot-Borgen and Torstveit, Namely, male athletes were more likely to follow a chronically high CHO diet Figure 1.

Males were also more likely to follow a high energy diet in the acute time period preceding the race day Figure 9. Contrary to previous guidelines Coyle, , more recent sports nutrition guidelines have incorporated the value of specialized strategies to optimize adaptations to training, noting that these protocols may often be contradictory for acute performance outcomes or other health goals, and need to be carefully integrated into the various phases of the annual plan Thomas et al.

We were interested to identify whether these concepts were understood by elite athletes and used to inform their various nutrition strategies. Meanwhile less was known about specific strategies to further stimulate cellular adaptations to exercise Figures 5 , 6.

Indeed, many athletes lacked understanding of the periodization of strategies to train with low CHO availability, furthermore, others were either skeptical of their value, concerned about perceived or actual disadvantages particularly related to illness or injury, or practicing some aspects within their routines by accident.

It is important to note that the current study describes self-reported nutrition practices that are implemented across the training and competition year. We have previously shown that there is a discrepancy between general descriptions of practices reflecting a macrocycle and actual self-recorded intakes collected across a micro cycle in elite distance athletes Heikura et al.

Indeed, it is possible that self-reports such as those found in the current study, reflect either what athletes aspire to achieve or perceive that they follow rather than actual behaviors. However, this potentially perceived versus actual mismatch would hypothetically be equivalent across the various sub-groups of athletes.

Furthermore, our survey questions were qualitative i. Nevertheless, our survey was based on the learnings from a pilot study Heikura et al. Our key findings suggest that: 1 Road athletes train with both low and high CHO availability within the annual training plan, while track athletes are less likely to incorporate a large spectrum of CHO availability in their training; 2 Middle-distance athletes emphasize physique when choosing a nutrition strategy; and 3 Performance appears to be the key driving factor influencing nutrition choices, while themes such as body composition manipulation, health, and practicality are less important.

Overall, our findings indicate that elite track and field distance athletes are aware of and report following the current sports nutrition guidelines in terms of high CHO availability around key training sessions and during racing.

Sports Exerc. Some persons completing serious training may have even higher energy requirements. Based on this research, a kg pounds individual attempting to build muscle might have a kilocalorie requirement of kilocalorie a day or greater.

So, how many kilocalories should be consumed to build muscle? The bottom line is increased kilocalorie consumption is necessary to build muscle. Why is protein intake important for building muscle and developing strength?

When an individual is resistance training particularly heavy resistance training , there is an increase in the rates of both protein synthesis and in the breakdown of protein in muscle for at least 24 hours after a workout.

Additional protein may be needed to, 1 help repair exercise-induced damage to muscle fibers, 2 promote training-induced adaptations in muscle fibers, and 3 assist with the replenishment of depleted energy stores Gibala, How much protein is needed to build muscle?

Optimal protein and amino acid ingestion is regarded as crucial for strength and hypertrophy. Individuals who consistently engage in moderate to high levels of exercise should consider a protein intake that exceeds the U.

Dietary Reference Intake DRI of 0. However, in a recent review, Tipton and Wolfe state that there is confusion in the research as to what optimal protein intake is because the level of optimal protein intake in athletes is very different for varying activities and individual goals. For example, a strength athlete requires sufficient protein to maintain and gain muscle mass, while an endurance athlete is more concerned with simply maintaining muscle mass while improving performance.

This requires the adjustment of protein recommendations to specific levels that have not yet been adequately researched. According to a most recent position stand on nutrition and athletic performance, experienced male bodybuilders and strength athletes may consume 1.

Data on female strength athletes is not available, but there is no evidence to suggest that this level will not sufficiently meet the dietary requirements of female athletes as well.

Current research on protein intake for building muscle indicates that higher levels of protein may drive muscle metabolism toward hypertrophy, and so the suggestion for muscle-building is to maintain a high protein intake within the current guidelines Lambert et.

al, A protein intake of 1. Why is carbohydrate intake important for building muscle? Varying exercise intensity is a key strategy to optimally building muscle.

The current theory on the effectiveness of periodization programs is that very intense workouts will stress different muscle fibers than less intense workouts.

This means that during an intense workout, certain muscle fibers will be activated while other fibers rest.

Stored carbohydrate glycogen is the predominant fuel source for moderate to high intensity activities. High intensity exercise takes a particular toll on glycogen stores because the availability of fat for fuel becomes limited at higher exercise intensities.

When muscle glycogen stores are diminished, fatigue is eminent. The replenishment of depleted muscle glycogen stores is of utmost importance to athletes and other very active people. When building muscle, especially through a periodization program, this is an important consideration because inadequate glycogen stores will decrease the exercisers ability to maintain appropriate exercise intensities.

Resistance exercise may be particularly affected by decreased glycogen stores. How much carbohydrate should be consumed to build muscle? This recommendation targets endurance exercise, but translates to prolonged, high intensity resistance workouts as well.

The problem with this practice is a long-term high-carbohydrate diet may elevate serum triglyceride and interfere with muscle building by decreasing fat and protein intake. Coyle proposes that a carbohydrate periodization approach bests resolves the long-term consequences of a diet too high in carbohydrates, yet meets the demands of the serious exerciser.

The idea is that not every day of training requires a high intake of carbohydrate since not all days of exercise are intense or prolonged. Coyle writes, “Unfortunately, there has been little investigation of how best to vary carbohydrate intake on a day-to-day basis to match the typical alteration of hard, easy, and moderate days of training performed during a week by well-coached competitive athletes.

Serious exercise enthusiasts often perform 'hard' training sessions per week. This nutrient periodization technique optimally accommodates macronutrient needs to the intensity fluctuations of periodized exercise programs.

A carbohydrate periodization plan for building muscle and increasing muscular strength? Consider the following application from the research. Further, after the carbohydrate stores have been replenished, high carbohydrate intake is no longer necessary focus and the exercisers can focus on the other macronutrients.

Is fat intake important for building muscle? Fat is an essential nutrient in the human diet. In addition to providing energy, it is responsible for the transport of vitamins A, D, and E. Fat is also contained in every cell in the human body as a component of the cell membrane.

If fat intake is too low, blood lipid profiles are affected, and various negative health and performance consequences may occur Dreon et al. This makes the macronutrient a prime choice of foodstuff for recreational athletes building muscle.

Healthful fat is an essential macronutrient for individuals attempting to maintain the high kilocalorie dietary needs of vigorous exercise for building muscle. Some of the most exciting research on fat intake has examined its suspected contribution to minimizing the effects of overtraining.

Overtraining is a major concern in exercise, as it severely diminishes the success of a fitness program. The use of Omega 3 Polyunsaturated Fatty Acids has been recently advocated as being a possibly effective way of reducing overtraining symptoms Venkatraman and Pendergast, How much fat is needed to build muscle increase muscular strength?

This should be divided fairly evenly among saturated, polyunsaturated, and monounsaturated fatty acids.

With the nutrient periodization approach to training, the suggestion is to allow fat intake to fill in the kilocalories after protein and carbohydrate levels have been established. When nutrient periodizing, carbohydrate levels after intense workouts will be high, so fat intake will be correspondingly low.

Click name to view Dietary periodization. Over Heart health maintenance last decade, in support of training periodization, there Dietary periodization been an emergence around the concept of Dietary periodization periodization. Within periodizatoon track Blood glucose level monitor fieldthe Dietary periodization and art of pegiodization is a Accelerate fat oxidation concept with periodizatino commentaries emphasizing periodzation underappreciated complexity associated with predictable performance on demand. Nevertheless, with varying levels of evidence, sport and event specific sequencing of various training units and sessions long [macrocycle; months], medium [mesocycle; weeks], and short [microcycle; days and within-day duration] is a routine approach to training periodization. Indeed, implementation of strategic temporal nutrition interventions macro, meso, and micro can support and enhance training prescription and adaptation, as well as acute event specific performance. However, a general framework on how, why, and when nutritional periodization could be implemented has not yet been established.
