Sorry about that, it’s the internet. I’m not a doctor, but it was explained to me that proteins from different sources are not all the same and, while I can process protein from a variety of foods, I don’t do it as efficiently as with muscle proteins. The nutritionist I spoke to - who was a vegan and a vegan activist - said people like me need about 1-2 chicken breasts per week. It’s not uncommon, a lot of people who try to go veggie and can’t hack it just go back to meat without trying to figure out why they felt sick and tired. Other people have said it’s genetic based on your ancestors, but I haven’t seen a lot of evidence to support that. Other sources point to evidence you can alter the way your body processes things by following specific diet plans, but I’m not prepared to feel that shitty again to figure it out.

I’d advise you proof read future questions then. Your initial question came across as very dismissive and condescending.

Their all just using very personal examples to try and prove you wrong. You’re not.
