Understanding Your Calorie Deficit

What is a calorie deficit? A calorie deficit means eating fewer calories than your body burns. When you do this consistently, your body uses stored fat for energy, resulting in weight loss.

The math: 1 pound of body fat contains about 3,500 calories. So a 500 calorie daily deficit equals about 1 pound lost per week (500 x 7 = 3,500).
