Does rigorous exercise reduce the risk of obesity? Answers: A. What amount of exercise is optimal for adolescents? B. Do men exercise more than women? C. Does rigorous exercise reduce the risk of obesity? D. Do people who exercise have better nutritional habits? Response Feedback : Exercise is a factor that can directly affect body weight and thus risk of obesity. The relationship between gender and exercise and between exercise and eating habits—if such relationship exists—is associative. Gender does not cause amount of exercise, and eating habits do not cause exercise levels (or vice versa).
