Time Restricted-eating and Metabolic Health in Patients With Type 2 Diabetes

Sponsor

Mount Sinai Hospital, Canada

Enrollment

112 participants

Start Date

Feb 1, 2026

Study Type

INTERVENTIONAL

Conditions

Type 2 Diabetes Overweight (BMI > 25)

Summary

Time-restricted eating - where no food is consumed over a period of time - has been shown to promote weight loss and improve cardio-metabolic function. In individuals with type 2 diabetes, it is also been shown to improve glucose control. The investigators propose a randomized controlled trial to determine whether time-restricted eating is an effective therapeutic strategy that can preserve pancreatic beta-cell function and improve glycemic control early in participants with type 2 diabetes.

Plain Language Summary

Simplified for easier understanding

This study, called TEA TIME, is testing whether time-restricted eating (TRE) — limiting all food to a specific window of time each day — can help people with type 2 diabetes manage their blood sugar and improve metabolic health, compared to standard dietary advice. **You may be eligible if...** - You are between 18 and 75 years old - You have had type 2 diabetes for 10 years or less - Your BMI is 25 or higher - Your weight has been stable for the past 3 months (less than 5% change) - You are managing diabetes with lifestyle changes only, or with metformin, DPP-4 inhibitors, or SGLT2 inhibitors **You may NOT be eligible if...** - You are on insulin or other diabetes medications not listed above - You have significant kidney, liver, or cardiovascular disease - You are pregnant or breastfeeding - You have a history of an eating disorder - You work night shifts or have very irregular eating schedules that make TRE impractical Talk to your doctor to see if this trial is right for you.
