Intermittent Fasting for Runners: How to Get Lean, Build Muscle, and Improve Performance
Intermittent fasting (IF) is a popular dieting technique that has been gaining traction in recent years. It has been used by athletes and fitness enthusiasts alike to improve their performance, health, and physique. But what is intermittent fasting and how does it help runners?
Intermittent fasting is an eating pattern where you alternate between periods of eating and fasting. It is often used to achieve weight loss and improve metabolic health. The most popular form of IF is the 16:8 method, where you fast for 16 hours and eat during an eight-hour window. The 5:2 method allows the runner to take in only 500 – 600 calories each day for two non-consecutive days, and then eat a regular diet the other days. It is important to note that when intermittent fasting, you should still be getting adequate nutrition from your diet.
Benefits of Intermittent Fasting for Runners
Research shows intermittent fasting can improve metabolic health and blood sugar control by reducing insulin resistance, blood glucose, and triglycerides. It can also help to reduce body fat and increase muscle mass. A small study of 23 runners suggests that while intermittent fasting can reduce body mass, it does not impact running performance.
Intermittent Fasting and running is reported as a great way to get lean without going on a diet or cutting your calories, while also building muscle. Because eating fewer meals can help limit your calorie intake, intermittent fasting can be an effective weight loss tool. Some people take a more extreme approach to IF and only eat one meal a day. This type of fasting can be dangerous and should not be attempted without medical supervision.
In addition to helping you lose weight, intermittent fasting can also help improve your mood and energy levels. It can also reduce inflammation, improve heart health, and help protect against diseases like diabetes and cancer. Studies have found that intermittent fasting can also help improve your body’s ability to burn fat, which can be beneficial for runners.
Drawbacks of Intermittent Fasting for Runners
While intermittent fasting can be a great way to achieve weight loss and improve metabolic health, it can also have some drawbacks for runners. One of the main drawbacks is that it can decrease your body’s ability to burn fat, which can lead to fatigue and slower times during races. Another potential downside of intermittent fasting is that it can cause dehydration, which can be dangerous for runners. Lastly, if you are not getting enough calories and nutrients, you may not be able to perform at your best.
Tips for Intermittent Fasting and Running
If you are considering intermittent fasting and running, it is important to make sure that you are getting enough calories and nutrients. Make sure to eat a balanced diet that includes lean proteins, healthy fats, and complex carbohydrates. Drinking plenty of fluids is also important to help keep your body hydrated. It is also important to make sure that you are getting enough sleep and rest to ensure your body is able to recover and perform optimally.
It is also important to remember that everyone’s body is different and what works for one person may not work for another. If you are considering intermittent fasting, it is important to talk to your doctor or a nutritionist to make sure it is the right choice for you. They can help you find the best eating plan and make sure that you are getting all the nutrients you need.

However, it is important to remember that intermittent fasting can reduce fat burning in runners and can lead to dehydration and fatigue. It is important to make sure that you are getting enough calories and nutrients, and to talk to your doctor or a nutritionist to make sure it is the right choice for you.
Is it safe for runners to do intermittent fasting?
Studies have indicated that there are potential health benefits associated with intermittent fasting for runners. A 2020 meta-analysis published in the journal Nutrients suggested that intermittent fasting could lead to improvements in VO2max, a decrease in body mass and fat mass.
Does intermittent fasting benefit athletes?
The researchers discovered that those looking to reduce body fat, particularly for endurance athletes such as those competing in track and field, swimming, or cycling, would find intermittent fasting to be extremely beneficial.
Does intermittent fasting have beneficial long-term effects on health?
Extended periods of fasting, such as 24, 36, 48 and 72 hours, may not be beneficial and can be hazardous. Going too long without nourishment can cause your body to begin storing more fat as a reaction to starvation.
What are the benefits of incorporating intermittent fasting into a runner’s lifestyle?
