Time-Restricted Eating in Adults With Metabolic Syndrome: A Randomized Controlled Trial: Annals of Internal Medicine: Vol 0, No 0
Background: Time-restricted eating (TRE), limiting daily dietary intake to a consistent 8 to 10 hours without mandating calorie reduction, may provide cardiometabolic benefits. Objective: To determine the effects of TRE as a lifestyle intervention combined with current standard-of-care treatments on cardiometabolic health in adults with metabolic syndrome. Design: Randomized controlled trial. (ClinicalTrials.gov: NCT04057339) Setting: Clinical research institute. Participants: Adults with metabolic syndrome including elevated fasting glucose or hemoglobin A1c (HbA1c; pharmacotherapy allowed). Intervention: Participants were randomly assigned to standard-of-care (SOC) nutritional counseling alone (SOC group) or combined with a personalized 8- to 10-hour TRE intervention (≥4-hour reduction in eating window) (TRE group) for 3 months. Timing of dietary intake was tracked in real time using the myCircadianClock smartphone application. Measurements: Primary outcomes were HbA1c, fasting gluco
