Fasting has been more and more well-liked in recent years as a means of enhancing metabolic function, promoting weight loss and improving health. Fasting can enhance these advantages and promote general well being when paired with physical activity. In this blog, we’ll discuss the benefits of working out during a fast and also about when is the ideal time to work out during a fast.
Is it Good to Exercise While Fasting?
The answer is that many people can benefit from exercising during a fast. Your body uses fat that has been stored as energy when you exercise during a fast, which can improve fat burning and encourage weight loss. Exercise during a fast has also been shown to enhance insulin sensitivity, raise growth hormone levels and activate autophagy, a mechanism that aids in the removal of damaged cells and encourages cellular repair.
What Stage of Fasting is Best to Exercise?
The ideal stage of fasting for exercise may vary depending on individual preferences and goals. Here’s a breakdown of common fasting stages and their suitability for exercise:
During Intermittent Fasting
Exercise during periods of intermittent fasting, like the 16/8 approach (fasting for 16 hours and eating within an 8-hour window), is beneficial to many people. Towards the end of the fasting phase, right before breaking the fast, exercise can aid increase metabolic flexibility and optimize fat burning.
After Fasted Cardio
Engaging in cardiovascular workouts during a fast, including jogging, cycling or brisk walking, might boost fat oxidation and strengthen the heart. One common strategy used by people who practice intermittent fasting is to perform fasted cardio in the morning before breakfast.
During Prolonged Fasts
For longer fasting periods, such as 24-hour or 72-hour fasts, exercising during the fasting window is generally safe and may offer additional benefits. However, it’s essential to listen to your body and adjust the intensity and duration of your workouts accordingly.
Should You Workout During a 24-Hour Fast?
It’s normally safe to exercise during a 24-hour fast, and it might even boost the fast’s metabolic effects. Research has shown us minimal to moderate exercises, like yoga, walking, or mild strength training, are often well tolerated by people when they fast for a whole day. However, because of decreased energy, vigorous exercise or heavy lifting could be more difficult. To prevent overexertion, pay attention to your body, stay hydrated and give healing top priority.
Can You Exercise on a 72-Hour Fast?
While exercising during a 72-hour fast is feasible, you may need to exercise extra caution and pay closer attention to your body’s signs. While some people might be able to stick to their normal workout schedule and feel rejuvenated others can feel exhausted and perform less well. Exercise during a 72-hour fast should be done at a low to moderate intensity. Gentle movement, flexibility exercises or relaxation methods like yoga should be prioritized. If you feel very tired or dizzy, drink plenty of water, keep an eye on your energy levels and think about breaking the fast.

Stay Hydrated: Drink plenty of water before, during and after your workout to stay hydrated and support your body’s functions.
