Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat. It’s important to check with your doctor before starting intermittent fasting. Once you get his or her go-ahead, the actual practice is simple.
Yes, intermittent fasting is safe for most people but it is not for everyone. You should always check with your doctor before implementing a major dietary change, especially if you have a condition like diabetes.
With intermittent fasting, you only eat during a specific time. Fasting for a certain number of hours each day or eating just one meal a couple days a week, can help your body burn fat. And scientific evidence points to some health benefits, as well. Johns Hopkins neuroscientist Mark Mattson, Ph.D., has studied intermittent fasting for 25 years. He says that our bodies have evolved to be able to go without food for many hours, or even several days or longer.
