Type 2 Diabetes Clinical Trial
— DECIDEOfficial title:
DECIDE: DiEt ChoIce to Promote Type 2 Diabetes rEmission Supported by Community Pharmacists and Registered Dietitians
Type 2 diabetes is typically viewed as a chronic, progressive, and lifelong condition. Patients and their healthcare providers "manage" type 2 diabetes through lifestyle modifications and various types of medications designed to lower blood sugar. Exciting new research indicates that "remission" of type 2 diabetes - defined as returning blood sugar into the normal range without having to use medications - through therapeutic nutrition may be possible for many people living with the condition. We will examine the preference, adherence and clinical results of a low-calorie diet or low-carbohydrate diet in type 2 diabetes remission rates.
