2.Do not exercise while fasting
Fasting is beneficial for the body because it allows the body to eliminate all the impurities that build up over time. However, there are a few things to keep in mind during your fast if you want it to be a healthy one. First, keep in mind that during a fast, your body will not take in the normal amount of nutrients and will not produce the normal amount of energy that it normally does.
This means that, if at all feasible, you should reduce your daily energy requirements during a fast: During a fast, you should avoid strenuous physical activity because it can cause your blood pressure to drop too low, which can lead to a variety of health problems. During a fast, excessive physical exertion could cause permanent harm to the heart or kidneys.
