Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
