Medical nutrition therapy in impaired glucose tolerance: A non-pharmacological strategy.

Impaired Glucose Tolerance (IGT) carries a significant risk of progression to Type 2 Diabetes Mellitus, yet structured nutritional interventions remain underutilized in Indian clinical settings. This is an interventional study at NSC GMC Khandwa on the efficacy of Medical Nutrition Therapy (MNT) in regulating the blood sugar level of 100 adult patients with Impaired Glucose Tolerance (IGT). The subjects were treated to a three month custom made MNT program which included systematic dietary consultation as well as individualized calorie schemes with regards to the level of occupational activity. The results of post intervention tests showed that dietary compliance (8 to 46), regular exercise (16 to 34) and caloric awareness (44 to 71) have improved significantly. As a result, the percentage of patients who were rated as being high-risk according to the random blood glucose levels reduced drastically, by 54 to 32. Thus, we show that structured MNT is effective to alter the lifestyle behaviour and is effective in the reduction of glycemic risk among prediabetic population.
