Calorie Needs For Individuals With Impaired Glucose Tolerance

Calorie Needs for Individuals with Impaired Glucose Tolerance: A Critical Discussion

Impaired glucose tolerance (IGT) is a prediabetic state characterized by elevated postprandial blood glucose levels without meeting the criteria for diabetes mellitus. It is a significant risk factor for the development of type 2 diabetes and cardiovascular disease. Recent studies have highlighted the importance of dietary interventions in preventing or delaying the progression to type 2 diabetes in individuals with IGT. However, the optimal calorie needs for these individuals remain unclear.

Standard Lifestyle Interventions: Limits and Challenges

Standard lifestyle interventions, including physical activity and weight management, have been shown to be ineffective in preventing type 2 diabetes in individuals with isolated impaired fasting glucose (IFG), a highly prevalent prediabetic phenotype globally (Thirunavukkarasu et al., 2024). Here, we propose low-calorie diets as a promising strategy for diabetes prevention in this high-risk population.

Healthy Eating and Calorie Needs

Healthy eating is essential for individuals with prediabetes and diabetes, including those with impaired glucose tolerance. A well-planned diet should optimize blood glucose control, manage weight, and reduce the risk of cardiovascular disease. The American Diabetes Association recommends a balanced eating plan that emphasizes whole, unprocessed foods, including vegetables, fruits, whole grains, lean protein sources, and low-fat dairy products (American Diabetes Association, 2020). For added health benefits, individuals should limit sugar calories to 5% or less of their total daily calorie intake.
