The parent said "vegetarian meats" so I hope we can assume that's not meant to include tempeh and tofu (but rather things like TVP or mycoprotein products).
And while we're on the subject, Mike Israetel from Renaissance Periodization gives soy protein high marks for body builders. Good macros, good price, and highest amino acid profile score after milk/meat/eggs. Having tofu on hand is definitely helpful during a bulk.
Tempeh is easier to digest: the soy (fibers and amino acids) is pre-eaten by the mold.
I can drink milk but feel the same as you do with beans. When it’s fermented cheese I’m totally fine.
Can you eat falafels, tofu or slip peas? If so the hull may be the cause. Also beans trigger gaz on many people because they don’t eat much insoluble fibers, but after a while of regular consumption it comes back to normal. Don’t hurt yourself through, take care.
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
Fruits mostly contains soluble fibers, only their peel contains a bit of the insoluble one. For your next try consider instant mashed lentils/slip peas (flakes) or lots of mushrooms if you're rich enough. Adding a fair portion of hemp or nutritional yeast also increase the protein ratio. And tempeh is really a game changer. I wish the best for you.
