Clinical Inquiries: How can we keep impaired glucose tolerance and impaired fasting glucose from progressing to diabetes?

Lifestyle changes and some drugs can help. Lifestyle interventions aimed at weight loss of 5% to 10% of body weight along with moderate aerobic exercise such as brisk walking for 150 minutes a week are the most effective means to prevent impaired fasting glucose (IFG) or impaired glucose tolerance (IGT) from progressing to diabetes (strength of recommendation [SOR]: A, several meta-analyses, including a recent Cochrane review).
