Burning fat for energy isn't an idea. As for your hypothesis, hypothesis doesn't mean making up random stuff.
Indeed, but please read what you quoted. I didn't state that "burning fat for energy is an idea". See the word "burning" in what you quoted? neither do I.
"fat store used exclusive as energy store" IS an idea or hypothesis. One that underlies a lot of other assumptions and theories about nutrition, but is actually known to be wrong -- fat is used for a lot of other things as well (your brain is mostly made of fatty acids, for one; the skin is constantly lubricated with fat for another).
