    led the study, told Reuters Health. “Therefore, it would be important to combine
    calorie restriction and exercise to derive the benefits of weight loss and

    Villareal, from

    the effects of weight loss on bone loss in 30 women and 18 men whose average age
    was 57 years. The study subjects were overweight but not obese.

    For one year, 19
