Time-restricted Eating and High-intensity Interval Training for Metabolic Health in Adults With Overweight/Obesity

Recruiting now · Not applicable

Conditions studied: Overweight and Obesity

In brief

This study will investigate the effects of 12 months periodised time-restricted eating combined with high-intensity interval training compared with a control group on fat mass in adults with overweight/obesity. Participants in the intervention group will complete the intervention remotely and will receive follow-up by telephone. Before randomisation, after 6 months and after 12 months, the investigators will measure the participants' body composition, physical fitness, fasting blood glucose and insulin, blood lipids, and blood pressure. Physical activity, diet, sleep quality, appetite, and adherence to the intervention will also be measured. Secondary sub-analyses of sex differences in the responses to the intervention will be performed.
