A diet for diabetes prevention

A diet high in carbohydrates and fiber and low in fat can aid in weight loss for people at high risk of developing type 2 diabetes. Lifestyle factors such as a poor diet, minimal physical activity, and obesity are common risk factors for type 2 diabetes. Moderate weight loss achieved through healthy lifestyle interventions, such as a nutritious diet and increased exercise, is typically recommended for individuals at high risk.

While there is no general consensus on the ideal macronutrient quantities for weight loss in people at risk of type 2 diabetes, some studies suggest that any diet that results in sustained caloric reduction can be effective. However, specific macronutrients, such as carbohydrates, fats, or proteins, may provide particular benefits for people at risk.

The Diabetes Prevention Program (DPP) is a clinical trial that investigated the association between dietary intake and weight loss in people at high risk of developing type 2 diabetes. Researchers found that, after one year of calorie reduction, weight loss was associated with increased carbohydrate and fiber intake, while high fat intake was associated with reduced weight loss.

Implications:

This study suggests that a high carbohydrate, high fiber, and low fat diet may be a suitable option for people at high risk of developing type 2 diabetes. Fruits, particularly non-citrus fruit, and vegetables, such as tomatoes, dark green, and bright yellow vegetables, were identified by the researchers as particularly beneficial for weight loss in this cohort.
