There is strong and consistent evidence that obesity management can delay the progression of prediabetes to type 2 diabetes. According to the American Diabetes Association (ADA), lifestyle modifications with personalized diet plans, physical activity, and behavioral therapy should be encouraged in patients with type 2 diabetes who have overweight or obesity. However, there is no "one size fits all" approach, and if basic metabolic needs are met, the ADA recognizes that there are many ways for an individual to lose weight and improve their glycemic control. The most well studied is a caloric restriction with a 500-750 kcal/day energy deficit diet, and 200-300 minutes of exercise per week is recommended. In addition, nutritional education and counseling should be provided at the time of diagnosis and throughout care. Clinical benefits are observed with modest weight loss of 5%-10%: reduced cardiovascular risk factors and improved glycemic control. Although a ketogenic diet may have short-term benefits for weight loss, long-term efficacy and practicality are limited.
There is no evidence to support improvement of pancreatic beta-cell function with the use of oral ginseng or reduction of CVD with omega-3 fatty acids.
