My father likes to fast every once in awhile. one time he fasted for 5 days and he lost 2 inches around his waist. My record for the longest time for fasting is 3 days. To my fathers and my experience, the first 2 days are HELL, then on day 3 you are fine, but you have ZERO energy. Your body starts burning extra fat away even while you sleep. Keep up the good work!
