Leyla Weighs In: Time-Restricted Eating vs. Usual Eating–What Science Says

Time-Restricted Eating Study: Nutritionist Leyla Muedin details a Johns Hopkins Medicine study (published July 27 in Obesity) on time-restricted eating (TRE), a form of intermittent fasting that limits eating to a consistent 8–10 hour daily window, in adults with obesity and prediabetes or diet-controlled type 2 diabetes. In a 12-week trial of mostly female and Black participants, groups followed either a 10-hour TRE schedule or a usual 16-hour eating pattern, while all received a provided, personalized-calorie DASH diet intended to maintain starting weight. Both groups experienced similar modest weight loss and reported improved eating behaviors (more restraint, less stress eating, less hunger), with no differences in appetite hormones (ghrelin, leptin) or inflammation markers (CRP, cortisol). Leyla argues a higher-carb DASH diet may have limited measurable benefits and suggests repeating the study with a true low-carbohydrate diet; she also explains how fasting periods can lower insulin, support fat burning, and improve sleep by avoiding late meals.
