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.

Detailed description

In this study, eligible patients with type 2 diabetes will be randomized to either time-restricted eating or standard lifestyle. The hypothesis under study is whether time-restricted eating can improve pancreatic beta-cell function.

Conditions

• Type 2 Diabetes
• Overweight (BMI > 25)

Interventions

Type	Name	Description
BEHAVIORAL	Time-restricted eating	18 hours of fasting and 6 hour window of eating (between 2 to 8 PM) every day for 52 weeks.
