Recommendation
Appreciate that patient lifestyle counseling programs aimed at dietary and exercise modification initiated in overweight persons with the prediabetic state of impaired glucose tolerance can prevent the progression to diabetes.A

Evidence:

  • Three randomized controlled trials have examined the effect of intensive lifestyle interventions in overweight persons with impaired glucose tolerance on the incidence of diabetes, the largest of which was conducted in the U.S. (the Diabetes Prevention Program). These studies all found that programs providing regular individual counseling sessions on dietary and exercise advice aimed at reducing and maintaining a 5% to 7% weight loss resulted in a 42% to 58% reduction in progression to diabetes over 3 to 6 years (139; 140; 141).

Comments:

  • Impaired glucose tolerance is an asymptomatic condition that can only be detected through screening.
