But burning isn't how your body utilizes the calories. Some things burn just fine yet are entirely useless as a (human) food source, like wood. This complicates things.

Even more reason there is plenty of science to be discovered. Until then, the rough estimate we have is still proven to work (calories consumed minus calories burned).
