I first tried eating vegetarian to deal with some digestion issues. It made it worse. Especially spinach, broccoli and other high fiber foods. I switched to a 90% carnivore diet and everything cleared up digestion wise, and I also felt much better, healthier, and my skin cleared up. As you say, diet is very individualized.

What was your diet before? Anecdotally, most people I know who felt better after going keto-ish had horrible diets to begin with. Dramatic reduction in processed foods, beer, HFCS, etc.

Simply preparing food at home with fresher ingredients and being conscious of what you're taking in can account for much of the gains they experienced.

The vast majority of people on the planet don't eat 90% meat diets, but if we did it would be a disaster! I'm not saying it isn't the case with you, but anyone who experienced amazing gains shifting their diet to mostly meat should consider survivorship bias, and that the benefits are from cutting other things out, not adding tons of animal protein in.
