J Int Soc Sports Nutr 15, 10 The good news is that, as your body adapts to the fed-fast cycle, many of these side effects ease up over time. But can intermittent fasting benefit runners, or does it do more harm than good? From supplements to your morning drinks, here's how you can increase your odds of reaching triple digits. How much protein can the body use in a single meal for muscle-building?

Fasting and athletic performance -

But what about for endurance athletes? Can fasting provide any benefits in performance? Let us walk you through some pros and cons!

Perhaps the biggest argument for fasting is that it increases an athlete's fat oxidation capacity, supposedly leading to more efficient fat burning, prolonged energy, and an overall improved performance.

Because our glycogen stores are limited, fasted training forces the body to utilize fat as energy. Overtime, your body learns to adapt to burning fat rather than glycogen, providing sustainable energy during longer workouts since adipose tissue provides many more calories of energy than glycogen does.

Essentially, fasting can help your body become better at metabolizing fat rather than relying on carbohydrates. Although the pros sound promising, further investigation is needed to analyze the effects of fasting on endurance athletic performance.

There is conflicting data regarding the effects of fasting on glucose metabolism and physical performance in trained athletes. While some studies report decreased performance while fasted, others find no significant effects at all.

Even though fasting may allow for an increased ability of the muscles to use fat as fuel during exercise, it is unclear if this effect translates to better performance. There is evidence showing that relying on fat as fuel actually fails to enhance performance in long endurance races and athletes may find it difficult to continue performance at high intensities.

Furthermore, subjects usually show increased levels of perceived fatigue even if performance was not compromised. Another concern is that fasting oftentimes results in decreased caloric intake, which affects numerous aspects of health and performance.

As of now, there is little evidence to support the idea of endurance training and fasting-mediated increases in fat oxidation. It is generally recommended that endurance athletes should avoid high intensity training while fasting. For all athletes, it is crucial to consume a sufficient amount of energy and nutrients to support performance.

Inadequate energy intake can result in fatigue, weakness, and overall decreased performance. Because endurance athletes have greater nutrition requirements than the average population, fasting may be an impractical approach.

There are still studies that need to be done to improve our understanding of the effects of fasting in endurance athletes. So feel free to experiment with different types of diet, see if it agrees with your body, and remember that the best diet is the one that you can stick to!

Purees Sweet Savoury. I have found intermittent fasting very useful but must be mindful to replace energy once it is burnt. Which, as you said, can be difficult, especially if you need significant calories. Craig, thank you for this outstanding article.

With all the new scientific information regarding the benefits of intermittent fasting it can become confusing for athletes who are training and need optimal fuel and energy for sustained performance.

Your article explains well the nuances of the fasting practice as well as the need for athletes in training to resume their fuel and high protein intake throughout the day. This article gives me the confidence to resume my training and fuel regime to obtain peak performance especially when training for a rigorous endurance event carrying heavy weight.

Fasting has garnered interest since research in animals has shown that those consuming fewer calories tended to live longer, says craigm Click To Tweet The research on intermittent fasting is somewhat scarce, with intervention studies both low in number and participants.

Insights from Athletes Observing Ramadan Of course, athletes are always looking for the next edge they can gain over their competitors, and intermittent fasting potentially represents such an edge.

Intermittent Fasting and Adaptation In fact, more recent research suggests that, for some athletes, periods of time with less—or even no—energy intake may help enhance performance.

If you train in the morning, intermittent fasting may compromise training adaptations, performance, says craigm. When I was competing in bobsleigh, I weighed 95kg and trained for hours daily. As such, I had to consume around calories per day, which included g of protein.

Consuming all this in one or two meals, or a short time window, would have been hugely impractical and likely impossible due to feelings of fullness.

As a result, we can speculate that consuming more energy with fewer meals during intermittent fasting is unlikely to occur due to the huge volumes of food required. It also seems like a very good idea to consume energy, protein, and nutrients before, and in most cases for elite athletes, during training sessions.

This may not be possible during intermittent fasting, depending on the eating window and the time of day the athlete trains. You definitely have to consume energy, protein, and nutrients after training although likely not immediately after. This might be possible with intermittent fasting depending on both the training time and eating window.

If you have more than one training session per day—as many elite athletes do—intermittent fasting could make it harder to consume food both before your first session and after your second session. Concluding Thoughts Given that high-level athletes require much more nutrition than non-elite athletes and must spread out these nutrients across the day when they have multiple daily sessions, this time-restricted approach seems to be a sub-optimal option.

In the context of fasting, low glycogen carbohydrate reserves may limit the execution of repeated, intense efforts. Active adults reported a decreased speed in repeated sprints after fasting 14 hours per day for three consecutive days. Active students reported decreased power and anaerobic capacity after ten days of intermittent fasting as assessed by the Wingate stationary bike test, although the study reported that power increased in the same group after four weeks.

Men and women who followed a strength training program had similar gains in muscle mass and strength when practising intermittent fasting compared to a control diet.

There was no significant difference in muscle power between active men who did or did not practise intermittent fasting. However, one study reported an increase in strength and muscular endurance in active young adults after eight weeks of strength training combined with intermittent fasting.

So, as we see, the results vary greatly from one study to another and are influenced by several factors, including the type of fasting and its duration, the level of the athletes, the type of sport they practise and so on.

In addition, very few studies have been carried out in women. Also, the lack of a control group in most studies means the effect of intermittent fasting cannot be isolated. So for the moment, it is not possible to draw a conclusion about the effectiveness of intermittent fasting on athletic performance.

Athletes who wish to use intermittent fasting should consider several practical issues before starting. Are their training schedules compatible with this dietary approach? For example, does the period during which an athlete is allowed to eat allow them to consume enough food prior to doing physical exercise, or to be able to recover after the training?

And, importantly, what about food quality, given that athletes must consume sufficient protein to recover and maintain their lean body mass and limit negative impacts on their performance? Intermittent fasting may result in an energy deficiency that is too great for athletes with high energy needs to overcome.

This could be the case for endurance athletes running, cycling, cross-country skiing, triathlon, etc. due to their high volume of training. These athletes may end up suffering from Relative energy deficiency in sport RED-S , a syndrome that affects hormone secretion, immunity, sleep and protein synthesis, among other things.

It is also important to question the motivation for adopting a dietary practice as strict as intermittent fasting. Some people do it for religious reasons such as Ramadan.

Many popular diets make such grandiose claims, but few have provided any evidence to substantiate this—save for one; long-term caloric restriction. From a health standpoint, caloric restriction is essentially the fountain of youth.
