Determining Calorie Needs (Video)

We all know that human beings run on calories. The calories we intake can come from several
different sources, primarily from macro-nutrients such as carbohydrates, protein, and fat. Whenever we think of losing weight, the first idea that pops into mind is watching our calories. Most of us don't really even know what a calorie is or how many we may need.

A calorie is simply a measure of food as energy. Ideally, in order to maintain a normal body weight, you should consume only as many calories as your body burns. In order to lose weight, you should consume fewer calories than your body burns. And not surprisingly, when you consume more calories than you burn, you gain weight. So it's important to know how many calories you need.
