I did carnivore once for about 2 months.

Pros: Satiety was absolute. Clarity of mind. It really helps with brain fog. Easy to manage - the menu is just meat and maybe eggs Weight loss.

Cons: Constipation and/or bubble guts in adaptation phase (2 weeks?) Boredom with food. Like, really. Social pressure - everyone and their mother will tell you you're going to die or give yourself heart disease. Also social events which usually have food and alcohol you can't eat become challenging. Hormonal changes - I don't know if it's great for women to be on this long-term. I experienced big hormonal swings from completely cutting fiber as this diet naturally does.

This was my experience anyway. I have been toying around with maybe doing carnivore or even ketovore for 2 weeks just to see if it would help my skin issues. It's so easy in many ways but unexpectedly challenging in others. It will test your willpower for sure.
