Yeah, I removed a lot. Basically everything plant based. I have occasionally had a few blueberries, some parsley, lemon, and I make a certain meatloaf dish that has mushrooms in it. So I'm not 100% animal based, but about 98%.
The interesting thing is - before going carnivore, I was eating more "conventionally healthy" than probably 99.9% percent of people. I did occasionally eat sugar, but only homemade treats. I never ate processed food. I ate lots of whole grains. Tons of fruits and vegetables. All the "superfoods". Not very much meat and saturated fat.
Yes, I agree with your implication - people could do far, far better with their diets if they switched away from sugar and processed food.
But I was already doing that. And even so - the switch to carnivore was life-changing.
