I don't believe in extreme diets like this carnivore thing for long term use, but I do believe it could be a good elimination diet. I have a skin problem cause by yeast overgrowth, and I'm at my breaking point with it. Some stuff I read is to go with a diet like the carnivore diet to starve the yeast since they feed on sugars and carbs. Once you can get the overgrowth under control, you can then start adding stuff to your diet that won't cause the overgrowth to return. Lately I've cleaned up my diet as much as possible to see if that works, but if not, I'm going to try the carnivore thing for 3 weeks.
