Does voluntary fasting affect your health? I've decided to fast during the 13th, 14th, and 15th of every Islamic month. My trainer at gym told me that fasting too much will destroy my immune system. However, I believe that what he knew was of water fasting, ie, fasting for days without food and only water. He told me to fast only once every 15 days...otherwise I had plans of fasting at least once a week.
