No, it's an attempt at reductio ad absurdum that I don't believe has worked.
Physically heavier food does not cause you to become more fat, and physically lighter food isn't going make you thin, otherwise I could eat Cadbury's Crispellos for every meal instead of vegetables and be no worse off. The energy composition (or otherwise) of the food is what matters because the body needs to process it into Things What Makes Body Work.
