I can eat maybe one serving every few days regardless of the source. I can eat a lot of various fruits without issue(high fiber too). tofu is mostly ok. I have tried about once a year for 15-20 years.

I can eat a block of cheese a day and feel great. same with extremely lean chicken. When I try plants only without the problem foods, my energy and recover drops. I get depressed and I have huge protein cravings. If I try to squash that hunger with fats or carbs, I get fat. Just never been able to find a sustainable solution for my body
