Diet is a cornerstone of type 2 diabetes mellitus treatment. Current standard of care diet recommendations focus on caloric restriction and weight loss, goals which can be difficult to achieve. A moderate carbohydrate, high protein diet has been designed specifically for people with type 2 diabetes, and has shown promising results in preliminary studies. This diet, called the Low Biologically Available Glucose (LoBAG) diet, does not require caloric restriction or weight loss to produce beneficial effects. The purpose of this project is to expand upon the preliminary studies and to offer the LoBAG diet to a free-living population of people with type 2 diabetes (people who come to outpatient study visits for diet instruction, and then prepare and consume food in their own homes).
