The 16:8 diet is a version of intermittent fasting that restricts eating to an 8-hour window. During that time, you’re allowed to eat and drink what you want with no calorie restrictions. During the 16-hour fasting period, you can (and should) drink plenty of water. Black coffee and tea are fine, too.
What time period works best? Keeping your eating window earlier—say, from 7 a.m. to 3 p.m.—seems to be the most beneficial. The body’s biological clock is primed to eat earlier in the day, explains Courtney Peterson, PhD, assistant professor of nutrition at the University of Alabama at Birmingham. “ In most people, blood sugar control is best in the morning and gets worse as the day progresses. You also digest food faster in the morning. So there’s a metabolic advantage to eating earlier in the daytime,” she says.
But if that timeframe seems unrealistic, don't worry. Recent findings suggest that bumping your eating window
just a little bit later, from 10 a.m. to 6 p.m., could also be effective for weight loss.
