METABOLISM - DIETING - WEIGHT LOSSMETABOLISMHOW IT WORKS Your metabolism consists of almost all of your bodily functions, that all use up your body's energy supply to power their tasks. Some of these functions are simple ones, like the small but important cellular tasks that you wouldn't even notice are taking place in the body continually. When you are lying still, these functions continue to happen. Then there are the functions that you do notice, such as the flexing of a muscle, any movement during physical activities, your breathing, etc. The countless tasks your body performs consume calories, and the way your body uses up these calories is your metabolism. Your body has multiple sources of energy on an ongoing basis. There are stores of energy within the body, as well as some more immediate sources that are constantly being refilled. Your body primarily uses the food you consume to provide most of the energy it needs. Our bodys attempt to have us eat approximately the amount of calories we would use each day. If we consume the same number of calories that we use in a day, our bodies would require no stored energy, nor would it have a surplus. If, for whatever period of time, we are consuming more calories than we are using, our body cannot use this extra energy, and therefore it will store this energy for when it is needed. The way our bodies conserve this energy is by converting the calories into body fat. Then it can use a process that converts the body fat into energy when there is not enough calories coming in. When we are not consuming enough calories to supply the body's functions, the body must convert stored body fat into energy to support the tasks. This is the reason dieting involves reducing your caloric intake and adding physical activity, to have the body rely on body fat to be used up.
