Probably everyone needs meat, only some people need less than others because they're smaller. My parents and grandparents used to eat three bowls of rice every meal and very little meat (like a very very tiny portion of meat), not because they didn't want to but because there wasn't a lot of meat to go around. We're all pretty tiny lol.
I'm sort of average height but I have like no chest, probably because there wasn't enough meat and the future generation adapted by becoming smaller.
