Effects of Time-restricted Eating on the Incidence of Gestational Diabetes Mellitus in High-risk Populations: a Randomized Controlled Study
This is a randomized controlled trial, aiming to investigate whether a time-restricted eating (TRE) can reduce the incidence of gestational diabetes mellitus (GDM) in high-risk pregnant women. Investigators intend to conduct a 3-month randomized controlled study to compare the effects of 10-hour TRE and habitual eating time on GDM under the same energy intake.
