How strong is the evidence for 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 evidence is currently rated strong (84/100), built on 9 published studies, including 5 randomized controlled trials and 6 meta-analyses -- enough for real confidence in the effect.
