The Short Answer
Your body isn't converting all the mass of a burger into energy lol. Only some of the energy bound up in food is utilized by your body, and **none** of it comes from converting mass into energy. Your body takes chemical potential energy from bonds between atoms in your food and (after generally storing that energy in different chemical bonds) utilizes it to drive all the processes that keep you alive. Much of the actual mass of the food is used as raw material to make structures your body needs like new cells etc. Some of that material is used wholesale because your body can't produce it on its own (like vitamins). Any mass your body can't use generally leaves the body with other waste. Some food has more, and more energetic, bonds that your body is capable of converting into energy than others.
