Yes, nutrient timing can help with weight management. However, the most important factor for weight management is calorie intake.
If you want to lose weight, then you must be in a calorie deficit burn more energy than you consumeand if you want to gain weight, you must be in a calorie surplus consume more energy than you burn.
Fuelling well before training and competition allow athletes to push hard to maximise performance. Underfuelling can limit this potential and, if accompanied by insufficient recovery after previous training sessions, can significantly increase the risk of injury.
Protein intake is essential for the growth and repair of muscles after exercise and regularly throughout the day. If this is neglected, recovery can be impaired and potentially result in injury or loss of muscle mass.
Nutrient timing is most important for two kinds of people 1 Professional athletes 2 People having or recovering from serious medical conditions, e. Type 1 diabetics. Yes, a Performance Nutritionist will set nutrient timing for athletes to maximise their recovery, performance and training adaptations for each specific training session.
They need to perform at optimal conditions consistently and maximise every marginal. Fuelling at the wrong times i. eating more calories the rest of the day can lead to increased calorie intakes resulting in higher body fat levels.

| Importance of timing your meals as an athlete | NSW Institute of Sport (NSWIS) | Instead, what you eat for breakfast has become the hot topic. Many professionals now recommend a low-carb, high-fat breakfast, which is claimed to improve energy levels, mental function, fat burning and keep you full. However, while this sounds great in theory, most of these observations are anecdotal and unsupported by research Additionally, some studies show that protein-based breakfasts have health benefits. However, this is likely due to the many benefits of protein, and timing probably does not play a role Your breakfast choice should simply reflect your daily dietary preferences and goals. There is no evidence to support one best approach for breakfast. Your breakfast should reflect your dietary preferences and goals. This reduction of carbs simply helps you reduce total daily calorie intake, creating a calorie deficit — the key factor in weight loss. The timing is not important. In contrast to eliminating carbs at night, some research actually shows carbs can help with sleep and relaxation, although more research is needed on this This may hold some truth, as carbs release the neurotransmitter serotonin, which helps regulate your sleep cycle. Cutting carbs at night is not a good tip for losing weight, especially since carbs may help promote sleep. However, further research is needed on this. Instead, focus your efforts on consistency, daily calorie intake, food quality and sustainability. Whether your diet is high or low in carbs, you may wonder if timing matters to reap their benefits.

By Rudy Mawer, MSc, CISSN — Updated on June 3, Nutrient timing involves eating foods at strategic times in order to achieve certain outcomes. Here is everything you need to know about nutrient timing. A Brief History of Nutrient Timing. However, a closer look at the research shows that these findings are far from conclusive, and have two significant limitations 1 , 5 : Short-term blood markers: Many of the studies only measure short-term blood markers, which often fail to correlate with long-term benefits 6. Ultra-endurance athletes: Many of the studies follow extreme endurance athletes, which do not necessarily represent the average person. Bottom Line: Nutrient timing has been around for several decades. The Anabolic Window: Fact or Fiction? The theory is based on two key principles: Carb replenishment: After a workout, an immediate supply of carbs helps maximize glycogen stores, which can improve performance and recovery. Protein intake: Working out breaks down protein, so post-workout protein helps repair and initiate growth by stimulating muscle protein synthesis MPS. Carb Replenishment One main aspect of the anabolic window is carb replenishment, since carbs are stored in the muscles and liver as glycogen. Protein Intake The second aspect of the anabolic window is the use of protein to stimulate muscle protein synthesis MPS , which plays a key role in recovery and growth. Bottom Line: The anabolic window is a period of time after workouts that is said to be crucial for nutrient intake. Nutrient Timing Before You Train. The pre-workout window may actually be more important than the anabolic window. Bottom Line: Nutrient timing may play an important role in pre-workout nutrition, especially if you want to maximize performance, improve body composition or have specific health goals. Nutrient Timing at Breakfast. As with the anabolic window, the breakfast myth is not supported by research. Bottom Line: There is no evidence to support one best approach for breakfast. Nutrient Timing at Night. Though these findings are somewhat mixed, the available data does provide support that adding Cr to a post-exercise regimen of CHO and PRO may help to facilitate greater improvements in body composition during resistance training [ 84 , 85 , 88 , 90 ]. The addition of CHO may increase PRO synthesis even more, while pre-exercise consumption may result in the best response of all [ 9 ]. The scientific literature associated with nutrient timing is an extremely popular, and thus ever-changing, area of research. Upon reviewing the available literature, the following conclusions can be drawn at this point in time:. whey and casein exhibit different kinetic digestion patterns and may subsequently differ in their support of training adaptations. However, including small amounts of fat does not appear to be harmful, and may help to control glycemic responses during exercise.

Abstract Position Statement: The position of the Society regarding nutrient timing and the intake of carbohydrates, proteins, and fats in reference to healthy, exercising individuals is summarized by the following eight points: 1. Nutrient timing and exercise: a review of the literature Introduction Previous research has demonstrated that the timed ingestion of carbohydrate, protein, and fat may significantly affect the adaptive response to exercise. Nutrient timing: pre-exercise Nutritional considerations prior to exercise have traditionally examined the administration of CHO to maximize endogenous glycogen stores [ 2 — 6 ] and maintain serum glucose levels during endurance exercise [ 4 , 7 ]. Nutrient timing: during exercise Much like the consideration of pre-exercise nutrient supplementation, a majority of the literature which has examined the impact of nutrient administration during exercise has focused on aerobic exercise [ 33 — 36 ], with a lesser emphasis on nutrient administration during resistance exercise [ 37 — 41 ]. Glucose administration during endurance exercise The initial research which dealt with nutrient administration during exercise scrutinized the optimal delivery of CHO in an effort to sustain blood glucose. Mixing carbohydrates to increase carbohydrate oxidation A fairly novel area of research has examined the impact of mixing various forms of CHO in an effort to promote greater levels of CHO oxidation during prolonged exercise. Adding protein or amino acids to carbohydrate during endurance exercise The addition of PRO to CHO during exercise has also been investigated as a means to improve performance and facilitate recovery. Addition of protein, amino acids and carbohydrate during resistance exercise Delivering nutrients during single bouts of resistance exercise has been used to determine their impact on changes in muscle glycogen [ 40 ], mitigation of muscle damage [ 13 , 37 ], and promotion of an anabolic response [ 38 , 39 , 41 ]. Nutrient timing: post-exercise Many nutritional interventions have been considered to enhance recovery from exercise. Maximization of muscle glycogen re-synthesis Athletes who ingest 1. Acute changes in amino acid kinetics and protein balance A single bout of resistance training modestly stimulates PRO synthesis, but also further stimulates PRO breakdown resulting in an overall negative PRO balance after exercise [ 75 , 76 ]; an effect which shifts PRO balance more towards neutral as training status progresses [ 76 ]. Post-exercise supplementation for promotion of training adaptations In an attempt to stimulate greater adaptations associated with resistance training researchers have investigated the impact of administering varying combinations of CHO and PRO after 1 — 3 h post-exercise each exercise bout over the course of training [ 8 , 10 , 32 , 84 — 91 ]. Conclusion The scientific literature associated with nutrient timing is an extremely popular, and thus ever-changing, area of research.

| Importance of timing your meals as an athlete | The authors suggested that because intermittent activities rely on anaerobic glycolysis to provide fuel, adequate glycogen stores needed to be achieved prior to exercise in order to optimize performance. However, many experts caution against pre-exercise fasting. And build in timing manipulation as you progress. It also guides post workout nutrition. Monitor your fluid intake throughout the day. |

Abstract Position Statement: The position of the Society regarding nutrient timing and the intake of carbohydrates, proteins, and fats in reference to healthy, exercising individuals is summarized by the following eight points: 1.
Nutrient timing and exercise: a review of the literature Introduction Previous research has demonstrated that the timed ingestion of carbohydrate, protein, and fat may significantly affect the adaptive response to exercise. Nutrient timing: pre-exercise Nutritional considerations prior to exercise have traditionally examined the administration of CHO to maximize endogenous glycogen stores [ 2 — 6 ] and maintain serum glucose levels during endurance exercise [ 4 , 7 ].
Nutrient timing: during exercise Much like the consideration of pre-exercise nutrient supplementation, a majority of the literature which has examined the impact of nutrient administration during exercise has focused on aerobic exercise [ 33 — 36 ], with a lesser emphasis on nutrient administration during resistance exercise [ 37 — 41 ].
Glucose administration during endurance exercise The initial research which dealt with nutrient administration during exercise scrutinized the optimal delivery of CHO in an effort to sustain blood glucose.
Mixing carbohydrates to increase carbohydrate oxidation A fairly novel area of research has examined the impact of mixing various forms of CHO in an effort to promote greater levels of CHO oxidation during prolonged exercise.
Adding protein or amino acids to carbohydrate during endurance exercise The addition of PRO to CHO during exercise has also been investigated as a means to improve performance and facilitate recovery. Addition of protein, amino acids and carbohydrate during resistance exercise Delivering nutrients during single bouts of resistance exercise has been used to determine their impact on changes in muscle glycogen [ 40 ], mitigation of muscle damage [ 13 , 37 ], and promotion of an anabolic response [ 38 , 39 , 41 ].
Nutrient timing: post-exercise Many nutritional interventions have been considered to enhance recovery from exercise. Maximization of muscle glycogen re-synthesis Athletes who ingest 1. Acute changes in amino acid kinetics and protein balance A single bout of resistance training modestly stimulates PRO synthesis, but also further stimulates PRO breakdown resulting in an overall negative PRO balance after exercise [ 75 , 76 ]; an effect which shifts PRO balance more towards neutral as training status progresses [ 76 ].
Post-exercise supplementation for promotion of training adaptations In an attempt to stimulate greater adaptations associated with resistance training researchers have investigated the impact of administering varying combinations of CHO and PRO after 1 — 3 h post-exercise each exercise bout over the course of training [ 8 , 10 , 32 , 84 — 91 ].
Conclusion The scientific literature associated with nutrient timing is an extremely popular, and thus ever-changing, area of research.

Athletic success is built on fundamentals. As you adapt to training and support your activity levels with the right foods, your performance will improve. But after a while, in order to really push your progress you will need another strategy layered on top.
And follow a healthy diet that supports their body composition and athletic performance. In other words, nutrient timing suits those that have already nailed their calories and macros.
Nutrient timing techniques provide a competitive edge in athletes whose physiques are primed. And build in timing manipulation as you progress.
As time has passed and research has grown, we now know that nutrient timing provides several key benefits:. Energy balance and food choices are key indicators of a healthy, performance-optimized diet. But evidence shows that timing is too.
Because your body utilizes nutrients differently depending on when they are ingested. Athletes are always looking for that extra edge over competitors. Nutrient timing is a key weapon in your performance arsenal. Providing your body with that push it needs to be successful.
It is therefore important to put strategies in place to help maximize the amount of glycogen stored within the muscle and liver. A diet rich in carbohydrates is key of course, but emerging research has shown that timing carb ingestion is important to maximize overall effects.
Note: While strength and team sport athletes require optimal glycogen stores to improve performance, most of the research into nutrient timing using carbohydrates has been conducted on endurance athletes.
Find out more about how glycogen storage can affect exercise performance in our dedicated guide Ever since the late s, coaches have used a technique called carb-loading to maximize intramuscular glycogen 3. The technique varies from athlete to athlete and from sport to sport , but the most traditional method of carb-loading is a 7-day model:.
There are variations on this model too. This technique has been shown to result in supersaturation in glycogen stores - much more than through a traditional high carb diet 4. The idea is to deplete glycogen stores with a low carb diet and high-volume training regime.
Then force muscle cells to overcompensate glycogen storage. Carb loading has been found to improve long-distance running performance in well-trained athletes, especially when combined with an effective tapering phase prior to competition 5.
Evidence shows that female athletes may need to increase calorie and carb intake in order to optimize the super-compensatory effect 6.
This is purely down to physiological differences. It has also been shown to delay fatigue during prolonged endurance training too 7. This is thought to be due to higher levels of glycogen stores, which not only provides more substrate energy but also decreases indirect oxidation via lactate of non-working muscles.
Carb-loading as part of a nutrient timing protocol can lead to glycogen supercompensation and improved endurance performance. Strategies for carb-loading involve high glycemic carbs during the loading phase, which helps to increase carb intake - but limit fiber high fiber will lead to bloating and discomfort.
Focusing on familiar foods is key in order to limit unwanted adverse effects. Carb-loading on the days prior to competition, or high-intensity training is one strategy to help optimize athletic performance.
Another is to ensure carb intake is increased in the hours beforehand. High-carb meals have been shown to improve cycling work rate when taken four hours prior to exercise by enhancing glycogen synthesis 8.
It is not recommended to eat a high-carb meal in the hour immediately prior to exercise due to gastric load and potential negative effects, such as rebound hypoglycemia 9. Instead, high-carb snacks, supplements or smaller meals can be used instead - and combined with fluids to optimize hydration.
Many athletes are turning to carb-based supplements to fuel up prior to exercise.
