That article, in a nutshell...
"You might lose weight, but it's mostly water weight. Fat is bad for you because it clogs your arteries, but I'm not going to cite any authority for this proposition, because it's just my opinion. People just don't want to eat low fat vegetarian diets."
First off, your body shouldn't be retaining excess water in the first place. Second off, people don't maintain low fat vegetarian diets BECAUSE THEY TASTE LIKE SHIT. Your body wants meat. What it evolved on.
I can't believe people get paid to write this kind of stupid shit.
