In 2011, a study published in the New England Journal of Medicine investigated the effects of weight loss, exercise, or both on physical function in obese older adults. The study involved 107 participants aged 65 or older who were obese (BMI ≥ 30). Participants were randomly assigned to one of four groups: control, diet (weight management), exercise, or diet plus exercise. The primary outcome was the change in score on the modified Physical Performance Test, with higher scores indicating better physical status. The results showed that the diet-plus-exercise group had the greatest improvement in physical function compared to the diet or exercise groups alone. The diet-plus-exercise group also showed greater improvements in peak oxygen consumption, functional status, and strength, balance, and gait. Body weight decreased in the diet and diet-plus-exercise groups, but not in the exercise or control groups. Lean body mass and bone mineral density decreased less in the diet-plus-exercise group compared to the diet group. Adverse events included a small number of exercise-related musculoskeletal injuries. The study concluded that combining weight loss and exercise provides greater improvement in physical function than either intervention alone. The findings suggest that weight loss combined with regular exercise may be beneficial in helping obese older adults maintain their functional independence. The study was funded by the National Institutes of Health.In 2011, a study published in the New England Journal of Medicine investigated the effects of weight loss, exercise, or both on physical function in obese older adults.
