I went like 90% vegetarian and switched to the meat substitutes. If I can do it, anyone can. I’ve always had a meat-a-saurus diet until 2-3 years ago.
I’ve only met one person who couldn’t go veg, because they had allergies to everything: soy, legumes, nuts.
There’s been a lot of obsession with protein in popular culture when in reality unless you’re a bodybuilder you don’t need a ton and a veg diet will suffice. And there are tons of vegan athletes.
The point I was making is that there is one step even the laziest can take to have an impact: just stop eating beef. Going full veg is better of course.
