A small study found that limiting food to small intervals each day can actually help people lose those extra pounds.
The authors found that limiting the “food window” to six hours might work as well as the stricter four-hour time frame, so there is no point in narrowing that window.
In an eight-week study, experts showed that both versions of interrupted fasting with a window at 4 and 6 hours helped obese people effectively lose weight. According to Krista Varady, a professor of nutrition at the University of Illinois, this weight loss tactic has become popular mainly because it is easy to follow. You do not need to count calories, but it is important to adhere to a clear dietary window limitation.
The results are published in the journal Cell Metabolism.
