Participants are randomly assigned to one of two groups:

1. Intervention group: 7 weeks of time-restricted eating (food intake is limited to a maximum of 10 hours per day) and 3 interval sessions per week. The participants will receive a diet and exercise guidance session, and then follow-up once a week during the entire intervention period.
2. Control group*: No intervention

The study period lasts a total of approx. 9 weeks.

The participants will have their body composition, physical fitness, and blood pressure measured, and blood samples will be taken to measure blood sugar and lipids. The study is carried out at the Faculty of Medicine and Health Sciences, NTNU and has been approved by the Regional Committee for Medical and Health Research Ethics.

*Those allocated to the control group will be offered the same diet and exercise program and the same follow-up as the intervention group, after the study period is completed. 

Criteria for participation:

• Men and women (we now have enough women, but are still recruiting men)
• Age: 18-50 years
• BMI of 27 kg/m² or more
• A habitual time window for when you eat that is 12 hours or more daily
