Should make some people question their assumptions - but it most likely will not. Understanding the biochemical processes that "run" our systems and some basic scientific principles should cause the shut down of fad diet pimps

It is hard for me to become convinced that I can somehow “fool” my body into not making fat out of excess calories from ANY source.

It goes round and round - and at no time does it violate the law of mass/energy conservation. If you take in excess energy - from whatever source - your body can and will turn it into lipids and store it as fat.
