Time-Restricted Eating and Staple Food Reduction Combined With App-Supported Exercise for Weight and Glycemic Control (TRE-SFR-EX)
21 июля 2026 г. обновлено: Peking University
A Multicenter Randomized Controlled Trial of Time-Restricted Eating, Staple Food Reduction, and App-Supported Exercise for Weight Loss and Glycemic Improvement in Adults With Obesity and Abnormal Glucose Metabolism
This multicenter, three-arm randomized controlled trial will evaluate the effects of early time-restricted eating and staple food reduction, each combined with an app-supported exercise intervention, on body weight and glycemic control among adults with obesity and abnormal glucose metabolism.
A total of 300 participants aged 18 to 50 years with BMI >=28 kg/m2 and impaired glucose regulation or diabetes will be enrolled at five centers in China and randomized 1:1:1 to app-supported exercise alone, staple food reduction plus app-supported exercise, or early time-restricted eating plus app-supported exercise.
The intervention lasts 12 weeks, followed by a 12-week post-intervention follow-up.

Подробное описание
All groups will use the Xiangdong Health app for exercise prescriptions, self-monitoring, and behavioral feedback.
The staple food reduction group will reduce staple food intake by approximately one half at three meals without restriction of eating time.
The early time-restricted eating group will consume food only between 07:00 and 15:00, with water allowed outside the eating window, without prescribed restriction of total daily energy intake.
Outcomes will be measured at baseline, week 12, and week 24, including body weight, glycemic indices, continuous glucose monitoring metrics, body composition, blood pressure, blood biochemistry, urine tests, stool microbiome, dietary recall, physical activity, sleep, appetite, psychological measures, adherence, and adverse events.
