Fast from time to time.

In some religions, fasting dates are based around set holidays; however, if you understand your body and its feelings, it should tell you when to fast. Fasting is something that your body needs from time to time to clean itself. Fasting will make you stronger and will help your body to regenerate.

1. Occasionally, skip a meal.
   This will make you stronger.

2. Once in a while, when it feels like your body needs it, fast for one full day.
