I did try it for a while. As bboy it's basically an elimination diet and even most of the fervent carnivore folks advocate some form of balance at some point. Not all...don't get me wrong...but most. Heck even that Paul Saladino dude who was like the poster boy for carnivore (and is also a physician) has injected (no pun intended) other foods such as fruit, honey, etc with pretty sound rationale as to why long-term or forever strict carnivore may not be great.
My bloodwork looked like dogcrap, even on my standard trt and I really didn't feel great even after weeks and weeks.
I've found a diet centered on beef, red meat, fish with the addition of easily digestable fruits and veggies ie carrots, peppers, pineapple, kiwi, oranges etc. works great as well as things like yellow potatoes, etc. More along the lines of what stan efferding advocates but I also do enjoy apples, nuts, etc. The absolute best I've ever felt and my bloodwork is right now and this was yesterday...
Meal 1
3 whole eggs
4 ounces of steak (from cow we purchased)
1 granny smith apple
8 ounces OJ
Meal 2
3 servings high protein greek yogurt (40 grams protein)
1 servings sea salted pecans
8 ounces pineapple
meal 3
12 ounces of beef (from a local cow we bought)
massive salad (4 cups of spinach/kale mix, onions, peppers, mushrooms, etc)
Meal 4
16 ounces fairlife milk
1 serving beef protein powder
massive pile of fruit
4-8 ounces of beef
I was sending what I ate to someone so thought I'd just share
I was strict carnivore, keto, etc. done it all...but I just keep coming back to some level of balance....
