In 6 months on carnivore I lost 65lbs. Never felt better. I eat beef, pork, chicken, eggs, etc. I only cook in lard or tallow. I only drink milk, water, or black coffee. Before I was 267lbs, high BP, High Cholesterol, now at a smidge over 200lbs, cholesterol and BP are now normal.
It’s a tough diet to maintain, especially when you’re busy. Cost isn’t so much an issue since we raise our own beef and pork.
In the past I’d tried other diets with no results, this is the only thing that’s actually worked for me.
Honestly once you sit down and look at it, it's not that much more expensive since you arent buying all the other crap. It evens out to a degree. I usually eat for less than $100 a week. It is tough when busy but you start learning the tricks over time.
It's the only way I've ever lost weight and kept it off for any length of time.
