I'm not a doctor, nor a nutrition expert, but I am an obsessive researcher/podcast-grinder.
I've used this penchant for rabbit-hole digging to begin building a massive categorized collection of all the different health problems—from cancer, to joint pain, to bad eyesight, to schizophrenia, and everything in between—which have garnered a mountain of testimonials by people (or doctors who've worked with patients) who have greatly improved, or in many cases eliminated these conditions by eliminating all plants (fruits, vegetables, and grains) from their diet, and eating strictly animal products.
If you are dealing with a health problem and looking for answers (or simply want to become your most optimal self), I encourage you to speak up; I'd be happy to look through my collection of resources for something that may be able to point you in a very promising direction. (And if you'd like to remain anonymous, feel free to DM me on Twitter or Nostr and I will keep your identity private.)
