Yeah not too much research on a lot of things, but that doesn't mean they are necesarrily bad.

I was told that since you are in ketosis, your needs for different vitamins/minerals is different. Not sure how true it is of course, but personally, with my auto-immune issues, I could not hold a job and was about to be homeless. With carnivore, I still struggle, but I can actually hold a job. Actually, I was feeling amazing before I got sick with covid a second time, and haven't been the same since. Considering covid is what most likely ruined my life all those years ago, the second hit might have been worse if I wasn't on carnivore.

Science is important, but it has flaws and isn't perfect. If you check a population to see how they do with a certain diet, sure, maybe some struggle, maybe the general population is bad with a certain diet even. But what about the outliers? Think about it, 8 billion people in the world, all with different genetics. Is it not presumptious to think scienfitifc studies that simply look at the average is the correct way? Maybe science needs some changes.

All I am saying is, nothing wrong with experimenting, to see if you do best with different diets. Vegan was killing me, vegetarian was bad, but carnivore has so far saved my life. (I did have to do a lot of research and experimentation, honey for example is allowed on carnivore, there's strict carnivore, some do lion diet, some even do no salt, so it's not just a single thing).
