I started doing a carnivore-close diet on 10-4 after listening to the Meat Eater podcast about it being intrigued, and have lost 16 pounds as of today. So if you want to shed some quick weight it's an easy way to do it. I wasn't really overweight either, I am 6'4" and started at 224 and am currently at 208. I do think that just eating a good balanced diet is best, and I thought I had that, but when I really looked at my diet it was awful and had too many processed and packaged foods.
Meal planning for the first two weeks was a pretty big deal, without that I wouldn't have made it very long. Once you get the hang of it though it's pretty easy to do, even for me and I love breads and sugars. The lack of sugar and carbs the first week was pretty rough, but not awful, after 2 weeks there were still some cravings but not as bad as before. There can be some pretty rough transitions in the bowel movement area the first two weeks as well.
I have a cup of black coffee in the morning, then I eat leftovers from the previous nights dinner for lunch, then I typically grill or pan sear a beef steak of some type, bison steak of some type, do elk burgers, elk roast, chicken or fish for dinner. I typically have one small side vegetable like zucchini or roasted broccoli that the fiber cancels out the carbs as much as possible. I know you're not supposed to do that, and that is why I consider it carnivore-close, but that has kept me on it just having some variety. I will typically have a cup of tea after dinner as a "dessert" replacement.
I see a whole lot of people when they get to the month mark say that they feel better than ever and are thinking clearer and it's the best way to eat, I think its good but I am just not to that point yet, and that could definitely have something to do with the small amount of vegetables that I am eating.
I should also mention, if you do it make sure to drink the necessary amount of water, the first 2 weeks I felt like I had a dry mouth most of the time even though I was drinking enough water. You do have to pee a lot so be prepared of that, as a southern whitetail hunter I’ve never had to pee off the stand so much in my life.
