Time-restricted eating improves measures of daily glycaemic control in people with type 2 diabetes

Diabetes Res Clin PractPublished Non-randomised pre-post trial

Authors' conclusion

Adhering 5 d/wk. to 9-h TRE improved glycaemic control in adults with T2D, independent of changes in physical activity or dietary intake.

Study context

Population
Adults with T2D (10 F/9 M; 50 ± 9 y, HbA1c 7.6% (60 mmol/mol), BMI ∼34 kg/m²)completed
Participants
19 adults
Comparison
9-h time-restricted eating (TRE) vs 2-wk Habitual period
Primary endpoint
24-h glycaemic control by continuous glucose monitoring (CGM) (mean 24-h glucose, 24-h total AUC, glucose variability)
Follow-up
4 wk
