A Comparison Between the Effect of Three Types of Low-Calorie Diets on Controlling Blood Glucose and Lipids in People with Type 2 Diabetes

The blood glucose level of people with diabetes can be normalized through an appropriate diet, physical activity, the use of chemical drugs and medicinal plants. This study aims to investigate the effects of low-calorie diets (1200, 1500, and 1800 kcal) on glucose and serum lipids in poorly controlled type 2 diabetic patients. This clinical trial was conducted among 60 patients with type 2 diabetes mellitus. The criteria for entering the study were fasting blood glucose higher than 130 mg/dl, hemoglobin A1C higher than 7% and BMI higher than 25. Blood glucose, fasting blood glucose and lipid levels were measured before and after intervention two hours after each meal. Patients were trained by an expert. Then, the questionnaires were completed and analyzed. In this study, the mean fasting blood glucose level in patients who used 1500 and 1200 kcal diet decreased significantly after intervention (p
