I can vouch for carnivore. Been doing it loosely for more than a year without being extremely strict and i already started to look a lot more shredded around December.
I recently came out of my 3 month strict diet and decided i will stick to it mostly, but consume small quantities of plant matter throughout the week for hormetic benefits (where you mildly stress your body with low amounts of phytotoxins).
I have not missed plants at all but i'm maybe not that picky of an eater.
It also saves me all the hassle of calorie counting, though i must say i don't really drink more than a handful of beers per year for the greater part of 2 decades now. Drinks are definitely the worst of the worst when jt comes to getting empty calories. Even eating pure sugar will give you a more satiated feeling than drinking it.
