Overweight and obese individuals with Type 2 diabetes who participated in an intensive 4-year lifestyle intervention program that increased their fitness and physical activity not only lost weight but also experienced an improvement in their glycated hemoglobin (HbA1c). Researchers randomly assigned 3,942 adults to a control group or to the intensive lifestyle intervention group, which included prescribed restricted caloric intake, 175 minutes weekly of physical activity, and 3 sessions each year with counselors through the entire 4-year period.
