Diet vs. Exercise

So why is exercise better?

1. Exercise changes your metabolism
Physical activity changes the energy equilibrium (your metabolism) of your body by increasing the amount of energy your body needs every day.

2. Cardio burns calories
One pound of fat is equal to 3500 calories. So to lose weight you need a calorie deficiency of 500 a day to lose a pound a week (500 x 7 days = 3500). It's better to eliminate calories with exercise because restricting food can actually lower your metabolism.

3. Activity breeds more activity
Studies show that individuals who exercise are generally more active throughout the day.

4. Working out builds muscle
You can increase muscle mass and the size of your muscle fiber by exercising (especially weight bearing activity). In order to nourish these fibers the body uses calories from fat that are stored in the body. As your energy requirements go up, you burn more fat during exercise and all day long. So the more muscle you have, the more calories your body burns, the faster you lose weight.
