About the trial
What the trial wants to find out
This trial will recruit participants who had gestational diabetes in their most previous pregnancy. Participants will be randomly allocated into two groups: one intervention group and one control group 6-12 weeks after giving birth. The intervention group will undergo an 8-week supervised intervention consisting of time-restricted eating and endurance exercise training with moderate-to-high intensity. The investigators will assess cardiorespiratory fitness, body composition, and other markers of cardiovascular and metabolic health before and after the 8 weeks. Additionally, the participants in the intervention group will be encouraged to continue exercising and eating time restricted after the supervised period and follow them up by telephone until one year from the baseline visit. The investigators will measure the same outcomes at the follow-up as on the previous two test points.
