I did eat yogurt when I did carnivore as I kept dairy products as part of the diet. After 5 weeks it just wasn’t worth continuing for me when I realized I could just mix in fruit and beans, feel just as good, and have the same health markers. I’m not denying everyone can thrive on a carnivore diet after a certain amount of time, but if you can get the same results without dealing with diarrhea for more than a month just by eating a couple other natural foods, then why not just do that. Having the runs for 5 weeks is not fun, but I will eventually try carnivore again and keep your points in mind.
Ultimately, what I believe it really boils down to is just completely removing ultra processed foods and added sugars from your diet, not eating beyond satiety, and getting all necessary nutrients (which meat is essential for).
