Time-Restricted Eating Is 'Promising, But More Data Are Needed'

Time-restricted eating — that is, reducing the number of hours a person is allowed to eat during the day — may produce a modest 1% to 4% weight loss, even without cutting calories, early studies in humans suggest. But more research is needed to provide definitive evidence.
This type of intermittent fasting also appears to improve blood glucose, blood pressure, and oxidative stress, said Courtney M. Peterson, PhD, a researcher at the University of Alabama at Birmingham, summarizing what is known about the potential weight-loss strategy at the virtual American Diabetes Association (ADA) 81st Scientific Sessions.
The best results were seen with early time-restricted eating (that is, ending the nighttime fasting early in the day) and allowing a person to eat 8 to 10 hours each day (eg, 8 AM to 4 PM or 8 AM to 6 PM), with fasting and only water allowed the remaining hours, she reported.
However, the three dozen or so studies in humans to date are mainly small, pilot, or single-arm studies lasting up to 3 months, and there are only three main randomized controlled trials with 25 or more participants in each group.
Large trials with around 260 participants are needed,
