Calories are energy...when you burn calories you release heat. They are not the fat itself, but when your body "heats up" the fat begins to burn. Also having muscle tone helps to burn fat because of the release of lactic acid.
That depends.If you have already burned all all the carbohydrates that you have ingested, and you have no or little body fat, you will start metabolizing your own muscle mass for energy.
Not necessarily. You can burn water, fat as well as protein
NO, you can burn calories from protein, starches, carbohydrates, or anything else that you consume.<br />
You wiil not start burning fat until you have gone past the amount of calories that you recently ate.
calories turn into fat and stays trapped in the body
First it's carbohydrates, then fat, then proteins I think
Noooope and bread is not the enemy either.
