Thinking you can exercise away calories
The saying that you can't out-exercise a bad diet is true, according to Dr. Apovian.
This mistake, "counting calories and then exercising the calories 'off,' doesn't quite work that way," she said.
The New York Times reported that, for weight loss, diet is actually more important than exercise. This doesn't mean you should stop exercising altogether, but rather that you shouldn't think of exercise as a means for eating anything you want.
