How many studies support Time-Restricted Eating?

Time-restricted eating (TRE) is supported by several well-designed randomized controlled trials, including a large NEJM trial that found calorie restriction with or without TRE, and a JAMA trial on early time-restricted eating, both showing meaningful weight loss but generally similar results whether or not meals were also restricted to a specific window. That's backed by 7 published studies in Vitaebase's database, including 4 randomized controlled trials, the most recent from 2026 -- a modest but real research base.
