Obesity is exacerbated more by EATING TOO MUCH than by lack of exercise.
It takes discipline to stay hungry and relish smaller meals.
Sorry. I'm not gonna take that blank assertion for granted. A sedentary lifestyle leads to a slower metabolic rate. More muscle mass burns more calories, even at rest, even while asleep. Lance Armstrong consumes more calories in a day than I do. And his left leg burns more of them in an hour than my whole body does in a day.
