Precise Eating Time to Improve Glycemic Control and Cardiometabolic Health in Prediabetes and Diabetes

Sponsor: German Institute of Human Nutrition

View on ClinicalTrials.gov

Summary

The objective of this study is to investigate the impact of hypocaloric time-restricted eating (TRE) at different day times (early versus late TRE) on glucose metabolism and other cardiometabolic parameters in individuals with overweight and with normal, or impaired glucose metabolism (prediabetes and type 2 diabetes). In addition, the study aims to elucidate the molecular mechanisms underlying these effects.

Interventions

BEHAVIORAL

Early Time-Restricted Eating

Participants will restrict their eating window (8 hours eating and 16 hours fasting per day) and caloric intake moderately. During the early TRE intervention, participants will primarily consume their meals in the morning. The precise eating window will be defined based on the individual chronotype of the participants. Additionally, participants will be required to reduce their daily caloric consumption by 25%. They will replace one daily meal with a calorie-reduced product to facilitate caloric restriction.

BEHAVIORAL

Late Time-Restricted Eating

Participants will restrict their eating window (8 hours eating and 16 hours fasting per day) and caloric intake moderately. During the late TRE intervention, participants will primarily consume their meals in the evening. The precise eating window will be defined based on the individual chronotype of the participants. Additionally, participants will be required to reduce their daily caloric consumption by 25%. They will replace one daily meal with a calorie-reduced product to facilitate caloric restriction.
