Time-restricted Eating and High-intensity Interval Training for Metabolic Health in Adults With Overweight/Obesity
Sponsor: Norwegian University of Science and Technology
Summary
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.

Interventions
Time-restricted eating and high-intensity interval training
1-month intense periods of maximal daily eating window of 10 hours and high-intensity interval training (three weekly, unsupervised, aerobic exercise sessions performed at \> 90 % heart rate maximum), separated by 3-month maintenance periods of time-restricted eating on 5 days per week and minimum 1 HIIT session per week. Each exercise session will last for 33-38 minutes. Participants will receive digital follow-up once weekly during intense periods, and once monthly during maintenance periods. The intervention period will be 12 months in total.
