Brief Summary

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

The goal of the research is to optimize an online and mobile multicomponent 12-month diet and lifestyle intervention for improving the blood glucose control of individuals with type 2 diabetes.

Detailed Description

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

The core of the program, administered to all participants, includes recommendations to follow a very low carbohydrate, ketogenic diet. The researchers will test whether adding the following experimental components will enhance the intervention's ability to improve health outcomes: (1) active vs. periodic self-monitoring of dietary intake using an "app"; (2) training vs. no training in positive affect; and (3) training vs. no training in mindfulness and mindful eating.
