We know we eat to get energy and it's measured in Calories. Just a quick reminder of elementary science. When one eats, food is being digested to glucose, amino-acid etc But glucose give the better energy and it is got from carbohydrate. Through respiration, the broken down compound (glucose) is converted into energy. Excess glucose is store in the liver or body muscles as glycogen to be used later. Here we try to examine the food one eat and energy it produces. If this energy is not consumed (or burnt out), it adds up to the body fat.
