Yes, but it's best not to eat less because of quick success and instant benefit, but to eat when it's time to eat. If you don't eat, your blood sugar will be lower, and you will feel dizzy after strenuous exercise. Wrong eating habits can also lead to stomach problems. In addition to your fat consumption, exercise can also lead to the loss of other body elements. Although you will get a beautiful curve in the long run, it is really not worth the loss to fall into chronic diseases.
