Intermittent Fasting: Proven Health Benefits with No Downsides, Says Science.

Intermittent fasting or restricting eating to a certain number of hours per day has no downsides and can have health benefits such as controlling blood sugar, promoting heart health, reducing excess weight, protecting against chronic disease, and possibly delaying cognitive decline. Short-term food-free intervals can work for almost everyone, even those with physically demanding lifestyles. However, days-long fasting can cause muscle loss and other problems. The ideal ratio of how much to eat and when may exist, but science has yet to figure out what that is.
