While many diets focus on what to eat, intermittent fasting is focused on when you eat. Calorie restriction, a form of dietary intervention that involves a reduced daily caloric intake, exerts physiological benefits with extended longevity and decreased risks for many age-related diseases in model organisms and humans 3.

Apr 20, Updated Nov 17, Learn more about SCL Health's Nutrition and Weight Loss and Bariatrics services. This is especially true when it comes to health and fitness trends, like Intermittent Fasting. Research shows that this popular diet can have powerful effects on the brain and body.

Intermittent Fasting is an eating pattern that alternates between periods of eating and fasting. So, the longer you go between meals, the more your body exhausts its insulin supply. This is when you start burning fat.

Although ADF may offer benefits for fat loss, recent research shows that ADF is no more effective than traditional calorie restriction for promoting weight loss or preserving muscle mass 6 , Furthermore, like other types of calorie restriction, weight loss during ADF may be accelerated when combined with increased physical activity.

For example, combining ADF with endurance exercise may cause twice as much weight loss than ADF alone and six times as much weight loss as endurance exercise alone Alternate-day fasting may help you lose weight.

Some studies show that hunger ultimately goes down on fasting days, while others state that hunger remains unchanged 5 , 9 , However, research agrees that modified ADF with calories on fasting days is much more tolerable than full fasts on fasting days One study comparing ADF to calorie restriction showed that ADF increased levels of brain-derived neurotrophic factor BDNF after 24 weeks of follow- up.

Researchers concluded that ADF may induce long-term changes in BDNF and that this may promote improved weight loss maintenance. However, the researchers found that BDNF levels did not correlate with body weight changes in this particular study and suggested that these findings be interpreted with caution However, animal studies have shown that modified ADF resulted in decreased amounts of hunger hormones and increased amounts of satiety hormones compared to other diets 17 , 18 , Another factor to consider is compensatory hunger, which is a frequent downside of traditional, daily calorie restriction 20 , 21 , Compensatory hunger refers to increased levels of hunger in response to calorie restriction, which cause people to eat more than they need to when they finally allow themselves to eat.

In fact, many people who try modified ADF claim that their hunger diminishes after the first 2 weeks or so. After a while, some find that the fasting days are nearly effortless 5. The effects of alternate-day fasting on hunger are inconsistent.

Studies on modified alternate-day fasting show that hunger decreases as you adapt to the diet. Some studies have suggested that ADF may be more beneficial for preserving muscle mass than other types of calorie restriction,.

However, results from a recent, high-quality study suggest that ADF is no more effective for preserving muscle mass than traditional calorie restriction 6 , 8 , 16 , 25 , Losing weight and restricting calories is usually an effective way to improve or reverse many symptoms of type 2 diabetes Similarly to continuous calorie restriction, ADF seems to cause mild reductions in risk factors for type 2 diabetes among people with overweight or obesity 30 , 31 , ADF may also help reduce fasting insulin levels, with some studies suggesting that it may be more effective than daily calorie restriction.

However, not all studies agree that ADF is superior to daily calorie restriction 6 , 33 , 34 , Having high insulin levels, or hyperinsulinemia, has been linked to obesity and chronic diseases, such as heart disease and cancer 36 , A reduction in insulin levels and insulin resistance should lead to a significantly reduced risk of type 2 diabetes, especially when combined with weight loss.

Alternate-day fasting may reduce risk factors for type 2 diabetes. It can reduce fasting insulin levels in people with prediabetes. Heart disease is the leading cause of death in the world and responsible for about one in four deaths 38 , 39 , Many studies have shown that ADF is a good option to help individuals with overweight or obesity lose weight and reduce heart disease risk factors 1 , 4 , 8 , The most common health benefits include 1 , 8 , 13 , 14 , 42 , 43 :.

Alternate-day fasting may reduce waist circumference and decrease blood pressure, LDL bad cholesterol, and triglycerides. Autophagy is a process in which old parts of cells are degraded and recycled. It plays a key role in preventing diseases, including cancer, neurodegeneration, heart disease, and infections 44 , Animal studies have consistently shown that long- and short-term fasting increase autophagy and are linked to delayed aging and a reduced risk of tumors 46 , 47 , 48 , Furthermore, fasting has been shown to increase lifespan in rodents, flies, yeasts, and worms Moreover, cell studies have shown that fasting stimulates autophagy, resulting in effects that may help keep you healthy and live longer 51 , 52 , This has been supported by human studies showing that ADF diets reduce oxidative damage and promote changes that may be linked to longevity 9 , 15 , 52 , Their response to fasting differs depending on the day and specific part of their cycle.

Second, women may be more sensitive to changes in nutrient balance than men due to a molecule called kisspeptin. Kisspeptin controls an integral part of the reproductive pathway and is sensitive to hormones like insulin and leptin, which help us regulate hunger and satiety signaling.

Women have higher levels of kisspeptin than men, which may influence the effect of fasting. Third, women may respond differently to decreases in specific macronutrients, such as protein or carbohydrates.

If women are not eating adequate protein for their body weight and activity levels, the body will sense that amino acids the building blocks of protein are low. If amino acids are too low, it can negatively impact estrogen binding and a hormone called IGF-1 insulin-like growth factor 1.

Both of these are important for thickening the lining of the uterus during the menstrual cycle; if the lining does not thicken, it can negatively impact fertility. Evaluating female hormones can help you and your practitioner understand what is happening with your hormones so that you can structure the best intermittent fasting plan and assess if fasting is appropriate for you.

Retesting periodically when fasting for long periods can help to see if you need to adjust your intermittent fasting schedule.

Fasting glucose measures your blood glucose after an overnight fast. Fasting insulin can be a helpful biomarker to evaluate, especially for women interested in using intermittent fasting methods to help treat insulin resistance. Using a continuous glucose monitor can help you keep track of your blood glucose levels while fasting and can help you make sure levels don't drop into an unhealthy range.

A comprehensive stool test can help a practitioner understand each patient's unique nutrient needs and any digestive support that may be helpful while trying intermittent fasting. Repeating a stool test periodically while practicing fasting methods can help evaluate nutrient needs and continue personalizing support as much as possible.

Women can use intermittent fasting as part of a healthy lifestyle - they just need to fast differently than men! Intermittent fasting can be a great health tool for women, though women should understand they need to approach fasting differently than men. As women move through different hormonal phases in life, their fasting approach also needs to change.

Aligning a fasting schedule with your menstrual cycle is a good starting point to see if the benefits of fasting can work for you. The most important thing is to make sure you can listen to your body cues and work alongside a practitioner to ensure you don't experience any adverse effects on your hormones from an intermittent fasting protocol.

Of the three methods, time-restricted eating TREwhich does not involve any calorie restriction, is the most popular. So far, however, studies have shown varying results regarding the health impact of this diet type. One review of studies looking at individuals with overweight or obesity showed TRE to be as effective as calorie restriction for weight loss. Another studyhowever, found no significant difference in weight loss between those following TRE and a control group.

Mice that are homozygous regulatiom the diabetes spontaneous mutation Lepr db have been widely used to model type 2 diabetes 10 Indeed, experimental studies in Lepr db mice support that intermittent fasting improved glycemic control, lipid dysregulation 1213hepatic steatosis 14retinopathy 15and cognitive impairment However, if and how intermittent fasting may rescue vascular dysfunction in type 2 diabetes has not been studied.

Furthermore, adipose-derived hormones, i. Adiponectin is an adipocyte-derived hormone that increases with weight loss and protects the endothelium by decreasing oxidative stress and inflammation 20 — Leptin and resistin, in contrast, are adipokines that are positively correlated to body weight and fat mass 24and weight loss decreased their levels Leptin and resistin have been implicated to cause endothelial dysfunction by promoting oxidative stress 17 In view of this, it is plausible to speculate that weight loss strategies, such as ADF, would increase adiponectin and decrease leptin and resistin concentrations.

In turn, the improvements in adipokine profiles may have a protective effect on the vasculature resulting in improved endothelial function. Here we aimed to determine the effects of ADF on glucose metabolism and endothelial function, and the involvement of adipokines, in type 2 diabetic mice and their respective non-diabetic controls.

We hypothesized that ADF regulates the adipokine profile, particularly adiponectin, which exerts vascular protective effects in type 2 diabetic mice with ADF.

To test this hypothesis, heterozygote control mice m Lepr db and homozygote type 2 diabetic mice Lepr db were treated with ADF for 12 weeks. We determined: 1 if and how ADF affects weight loss, glucose metabolism, and insulin sensitivity in type 2 diabetic mice; 2 if and how ADF affects circulating adipokines and their expression in adipose tissue; 3 how ADF rescues endothelial dysfunction, and if and how adipokines, including adiponectin, resistin, and leptin, modulated by ADF may contribute to the vascular benefits of ADF; and 4 whether and to what extent ADF influences glucose metabolism and vascular function in non-diabetic control mice.

The procedures followed were in accordance with approved guidelines set by the Animal Care Committee at the University of Missouri Columbia, MO, United States. Mice were purchased from the Jackson Laboratory Bar Harbor, ME, United States. Homozygote type 2 diabetic mice Lepr db ; BKS.

The heterozygote control mice m Lepr dbblack and lean from the colony are heterozygous for Dock7 m and heterozygous for Lepr db. Because of the sterility of Lepr db homozygotes, the misty Dock7 m mutation has been incorporated into stocks for maintenance of the diabetes mutation 10 The repulsion double heterozygote facilitates the identification of heterozygotes for breeding 10 Mice that are homozygous for Dock7 m and wildtype for Lepr from the colony gray and lean are discarded 10 The Lepr db mice demonstrate morbid obesity, chronic hyperglycemia, and are polyphagic, polydipsic, and polyuric 10 Heterozygotes control mice m Lepr db are normal in body weight, blood glucose, and plasma insulin 10 Mice were maintained on a standard rodent diet.

Twelve to sixteen week-old, male, 20—35 g m Lepr dband 40—60 g Lepr db mice were used in this study. Mice were fed ad libitum on alternate days and then moved to a separate cage without food starting at 9 a. for 24 h to prevent food from being stored in the bedding.

First Thing First: What exactly is Intermittent Fasting?

The researchers did not measure estradiol, estrone, and progesterone in participants at premenopausal stage, as levels of these hormones change over the course of the menstrual cycle. Both groups lost weight during the study. This suggests that time-restricted eating may be a good diet to help people lose weight and prevent the progression of prediabetes to diabetes.

Krista Varady , lead author, and professor of nutrition at the University of Illinois, Chicago. Of all the hormones measured, only one, DHEA, was significantly affected by the change in eating patterns. In both groups, DHEA concentration dropped after 8 weeks of TRE. DHEA is a steroid hormone that is made in the body by the adrenal glands, the gonads, and the brain.

It is important for creating estrogen and androgen hormones , such as testosterone. In females, low levels of DHEA are associated with reduced libido, vaginal dryness, and osteoporosis. Studies have also shown that supplementing DHEA may improve success rates in females undergoing fertility treatment.

And although it is widely believed that low DHEA might reduce fertility, there is little peer-reviewed research to support these claims. High levels of DHEA are associated with an increased risk of breast cancer , particularly estrogen receptor-positive and progesterone receptor-positive tumors, in both premenopausal and postmenopausal individuals.

However, among postmenopausal females, a decrease in DHEA may induce sexual dysfunction, diminished skin tone, and vaginal dryness. But these negative effects were not reported in our study, since DHEA remained in the normal range.

However, Prof. This study was carried out on females with obesity. Varady stressed that more work is needed to see whether the results apply to other populations. We will also need to see how intermittent fasting affects fertility in men and women.

There are a number of studies currently looking into the benefits of intermittent fasting. Varady is researching whether intermittent fasting may be beneficial for those with polycystic ovary syndrome PCOS. And ZOE is running a large intermittent fasting study, the big IF study.

My understanding is that fasting overnight for 12—14 hours is likely beneficial for most of us, with positive effects on metabolism and healthy weight maintenance, especially if we can keep our eating window roughly the same day to day. There is a lot of hype around intermittent fasting, but what are its actual benefits, and what are its limitations?

We lay bare the myths and the…. This Honest Nutrition feature looks at the concept of food addiction, offering an overview of what scientists know and what they are yet to prove…. Can we use food and diet as medicine? In fact, many people who try modified ADF claim that their hunger diminishes after the first 2 weeks or so.

After a while, some find that the fasting days are nearly effortless 5. The effects of alternate-day fasting on hunger are inconsistent. Studies on modified alternate-day fasting show that hunger decreases as you adapt to the diet.

Some studies have suggested that ADF may be more beneficial for preserving muscle mass than other types of calorie restriction,.

However, results from a recent, high-quality study suggest that ADF is no more effective for preserving muscle mass than traditional calorie restriction 6 , 8 , 16 , 25 , Losing weight and restricting calories is usually an effective way to improve or reverse many symptoms of type 2 diabetes Similarly to continuous calorie restriction, ADF seems to cause mild reductions in risk factors for type 2 diabetes among people with overweight or obesity 30 , 31 , ADF may also help reduce fasting insulin levels, with some studies suggesting that it may be more effective than daily calorie restriction.

However, not all studies agree that ADF is superior to daily calorie restriction 6 , 33 , 34 , Having high insulin levels, or hyperinsulinemia, has been linked to obesity and chronic diseases, such as heart disease and cancer 36 , A reduction in insulin levels and insulin resistance should lead to a significantly reduced risk of type 2 diabetes, especially when combined with weight loss.

Alternate-day fasting may reduce risk factors for type 2 diabetes. It can reduce fasting insulin levels in people with prediabetes.

Heart disease is the leading cause of death in the world and responsible for about one in four deaths 38 , 39 , Many studies have shown that ADF is a good option to help individuals with overweight or obesity lose weight and reduce heart disease risk factors 1 , 4 , 8 , The most common health benefits include 1 , 8 , 13 , 14 , 42 , 43 :.

Alternate-day fasting may reduce waist circumference and decrease blood pressure, LDL bad cholesterol, and triglycerides. Autophagy is a process in which old parts of cells are degraded and recycled.

It plays a key role in preventing diseases, including cancer, neurodegeneration, heart disease, and infections 44 , Animal studies have consistently shown that long- and short-term fasting increase autophagy and are linked to delayed aging and a reduced risk of tumors 46 , 47 , 48 , Furthermore, fasting has been shown to increase lifespan in rodents, flies, yeasts, and worms Moreover, cell studies have shown that fasting stimulates autophagy, resulting in effects that may help keep you healthy and live longer 51 , 52 , This has been supported by human studies showing that ADF diets reduce oxidative damage and promote changes that may be linked to longevity 9 , 15 , 52 , The findings look promising, but the effects of ADF on autophagy and longevity need to be studied more extensively.

Alternate-day fasting stimulates autophagy in animal and cell studies. This process may slow aging and help prevent diseases like cancer and heart disease.

Nearly all weight loss methods cause a slight drop in resting metabolic rate 55 , This effect is often referred to as starvation mode , but the technical term is adaptive thermogenesis.

When you severely restrict your calories, your body starts conserving energy by reducing the number of calories it burns. It can make you stop losing weight and feel miserable Meanwhile, the ADF participants experienced only a 1. Alternate-day fasting may not decrease metabolic rate in the same way as continuous calorie restriction.

A 3-week study analyzed individuals with average weight following a strict ADF diet with zero calories on fasting days. It showed that following an ADF diet for 12 weeks reduced fat mass and produced favorable changes in risk factors for heart disease 8.

That said, ADF generally provides much fewer calories than you need to maintain weight, which is the reason you ultimately lose weight. The study followed a group of pre- and post-menopausal obese women who maintained an intermittent fasting diet that involved eating during a four-hour or six-hour period each day without calorie limits, then consuming only water until the same time next day.

The researchers compared the differences in hormone levels with those of a control group that followed no diet restrictions. They found that levels of a protein that carries reproductive hormones throughout the body was unchanged in the dieters after eight weeks.
