Intermittent Fasting Running: What You Need to Know
Intermittent fasting (IF) is an increasingly popular way to get lean without going on a diet or cutting calories. But what happens when you combine intermittent fasting with running? Here, we take a look at how intermittent fasting and running can work together to help you achieve your fitness goals.
What is Intermittent Fasting?
Intermittent fasting is an eating pattern that alternates between periods of eating and fasting. One of the most popular forms of IF is the 16:8 method, which involves fasting for 16 hours and eating for 8. Other methods include the 5:2 approach, which involves eating just 500-600 calories for two non-consecutive days and then eating normally for the other five days.
Intermittent Fasting and Running: Benefits and Risks
Intermittent fasting can have some big health benefits, such as weight loss, improved blood sugar control, and reduced inflammation. It may also help to improve running performance and reduce fat burning.
However, there are some potential risks to consider. A small study of 23 runners suggests that while intermittent fasting can reduce body mass, it does not impact running performance. There is also the risk of dehydration, fatigue, and nutrient deficiencies.
How to Use Intermittent Fasting and Running Together Safely
If you’re considering combining intermittent fasting and running, it’s important to do it safely. Here are some tips to get you started:
- Stay hydrated. Make sure to drink plenty of water during your fasting window and keep your electrolytes up.
- Eat enough. Make sure you’re getting adequate nutrition during your eating window. Focus on whole foods like fruits, vegetables, and lean proteins.
- Listen to your body. If you’re feeling weak or fatigued, take a break from running or reduce the intensity or duration of your workouts.
- Try different methods. Different types of intermittent fasting work for different people, so experiment to find what works best for you.
Intermittent Fasting and Running: A Great Way to Get Lean and Build Muscle
Intermittent fasting and running is a great way to get lean without going on a diet or cutting your calories, while also building muscle. Studies suggest that intermittent fasting can help to reduce body fat, improve insulin sensitivity, and increase muscle mass.
Intermittent fasting can also help you to become more mindful of your eating habits, which can help to reduce the risk of overeating and unhealthy snacking. Plus, it can give you more time to focus on other activities such as running.
Intermittent Fasting and Running: A Powerful Combination
Intermittent fasting and running can be a powerful combination for improving your health and fitness. It can help you to get lean, build muscle, and improve your running performance. Plus, it can help you to become more mindful of your eating habits and give you more time to focus on other activities.
However, it’s important to be mindful of the potential risks and take steps to mitigate them. Make sure to stay hydrated, eat enough during your eating window, and listen to your body. Experiment with different methods to find what works best for you.
Intermittent fasting and running can be a powerful combination for achieving your fitness goals. With the right approach, it can help you to get lean, build muscle, and improve your running performance.
Is it possible for me to exercise while following an intermittent fasting regimen?
Runners doing an intermittent fast should keep their runs at a low-intensity level. This means running with a rate of perceived exertion of 2-3 out of 10 or in heart rate zone 2 to ensure that fat is being burned as energy instead of glycogen, which is likely to be depleted in a fasted state. Jack Coxall, a strength and fitness coach, warns against running at a higher intensity, as it can lead to hitting the wall.
What are the long-term health benefits of intermittent fasting?
Going without food for extended periods of time, such as 24, 36, 48, and 72 hours, may not be beneficial and can even be hazardous. Fasting too long may cause your body to start conserving fat in anticipation of starvation.
What is the purpose of the 5:2 diet?
Alternate Day Fasting involves fasting one day and then eating regularly the next day, alternating between the two every 24 hours. This type of fasting is also known as the 5:2 diet, as it focuses on fasting two non-consecutive days each week, with the other days having no restrictions on what you eat.
