Impact of Diet on Glycemic Control in Overweight or Obese Niddm Subjects

Abstract

Diet is one of the fundamental therapies for overweight or obese non-insulin dependent diabetes mellitus (NIDDM) individuals to improve their glycemic control and lose weight. Objective: The aim of the study was to determine the effect of diet prescribed at Truweight diet centers on weight loss and glycemic response in the overweight or obese NIDDM individuals. Methods: The study participants (N=55) comprised of 21 males and 34 female overweight or obese NIDDM individuals between the age group of 24-64yrs. The participants were selected from Truweight Hyderabad diet centers using purposive sampling technique. Initial weight, fasting and postprandial blood sugars were collected using standard procedures. After 12 weeks of diet intervention the weight loss, fasting and postprandial blood sugars were recorded for analysis. Data was analyzed by paired t-test, Pearson's correlation, and regression coefficient using SPSS software. Result: In the present study, participants had a significant weight loss of 5.53+2.1 (6%) during the 12 weeks' intervention period. The Mean fasting blood glucose fell from 133 to 101 mg/dl (p<0.001). Mean postprandial declined from 181 to 132 mg/dl (p<0.001). The weight loss in this study predicts the drop in the postprandial blood sugars significantly (p<0.022). The response to the dietary intervention in both males and females was similar. Conclusions: Diet program had led to significant decrease in the initial weight, fasting blood sugar and the postprandial blood sugars in 12 weeks' study period in the NIDDM individuals. The diet program at Truweight made a significant impact on weight loss and glycemic control in both male and females NIDDM individuals.
