If you consume more calories than you burn, you will gain weight. If you burn more calories than you consume, you will lose weight.

What you consume affects metabolic and hormonal secretions which may cause you to store fat instead of expend fat, and vice versa. This is why the type of foods and beverages we consume are crucial.
