Summary

This project will determine the independent and combined effects of high intensity interval training and time-restricted eating on blood sugar regulation among women in reproductive-age who have overweight or obesity. The intervention period will be seven weeks. Before and after the intervention, blood sugar regulation, body composition and physical fitness will be measured and compared between groups who are doing either high intensity interval training, time-restricted eating, both high intensity interval training and time-restricted eating, or who are in a control group. Physical activity, sleep quality, continuous glucose monitoring, adherence to the interventions and hunger/satiety will also be measured.

Detailed description

In a follow-up study, we will invite randomized participants to come in for new assessments of physical fitness, body composition and fasting blood samples, and they will be asked to complete questionnaires about adherence to the interventions two years after intervention-end. The first participants will come in to the laboratory for the two-year follow up in November 2021.
