Summary

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.

Conditions

  • Gestational Diabetes Mellitus With Baby Delivered

Interventions

BEHAVIORAL

Time-restricted eating and exercise

The intervention is a combination of time-restricted eating and endurance exercise training. Time-restricted eating implies that the participants will be asked to limit their energy intake to a maximum 10-hour time window daily. The endurance exercise programme consists of 2-4 weekly supervised exercise sessions for 8 weeks. Thereafter, the participants will continue exercising unsupervised with weekly follow-up from researchers.
