I add the word "obesogenic" to my toolbox, love how it sounds!

I don't know Fruitarians but what you describe makes sense. However the vegans I know aren't "Hungry all the time". Some are skinny and some fatty but I wouldn't say the average are skinny, you wouldn't stare at their size if you don't know their diet. Might be a personal bias though, I don't know studies about vegans hungriness or BMI.
