TREHIIT - Time-restricted eating and high-intensity interval training with digital follow-up
Time-restricted eating (consuming all energy within a limited time-window each day) and high-intensity interval training are two strategies to improve metabolic health.
Our recent research has shown that time-restricted eating (TRE) with high-intensity interval training (HIIT)can rapidly induce several health benefits and decrease metabolic disease risk in women with overweight/obesity. Graphical abstract on the left summairzes our research. Reproductive-aged women with obesity and insulin resistance are at increased risk of type 2 diabetes and cardiovascular disease, and TRE is a popular dietary strategy that emphasizes the timing of meals in alignment with diurnal circadian rhythms.
We are now further investigating whether people can get the same benefits from time-restricted eating combined with high-intensity interval training even without close follow-up.
We are actively looking for particpants in the study. Below is a brief outline of our study
Participants will be randomly assigned to one of two groups:
- 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.
- 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
- 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
- Able to walk on a treadmill or ride a bike for at least 60 minutes
- Does not perform high-intensity interval training more than once a week.
- Understands oral and written Norwegian or English.
