Michael Steven asks if fasting will help him get back into shape at 57 years old. Yes 100%. its hard as hell the first two weeks, so pace yourself. start by waiting 4-6 hours to eat after waking up. do this 3-4 times a week, untill you can do for 7 days. just realize its not a diet, its fundamentally redefining your body for good. it is a new way of life. intermittent fasting was the fundamental springboard that catapolted my health and physique to greek god.
