In a new study, neither weight nor body mass index (BMI) changed noticeably six months after children switched to low- or reduced-fat dairy products. Instead of trimming their waistlines, kids who slashed fat intake appeared to compensate by eating more calories from other sources, according to the new findings. The same happens with adults. Our bodies require a certain amount of fat to function normally and fat helps slow down digestion and increase feelings of satiety.

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.
