I checked what I wrote. That is indeed what I said, and it is true, regardless of begetarianism or carnivorariasm, or omnivoracity. (I love inventing new words).
Yes, it definitely takes more land to produce meat. At least in large quantities. Ya grow the food for the meat animals, unless they are entirely free ranged, and the animals take space, more space for bigger animals obviously. Certainly at a large scale.
That said, (again), I will remind that I saw nothing in what I wrote about eating meat making people fat. But as far as the question about that just generally being accepted as true, I sure did not know that it was accepted as true or not.
Entirely aside, and because you made me think of it, all of the complete pure vegans I know, come to think of it, sure do appear quite thin to me.
I have hyperthyroid. Yep. This winter I definitely did lose weight. I have to do everything I can to keep it at a high percentage of muscle, (wiry ole guy muscle), and consume extra calories and good fats to keep my weight up.
Thinking some more, North Korea does have a problem with their farms producing enough food for it's people. That country's MacroEconomic management of their farm system is definitely not working.
