Some, and a newish thread was started But due to it being somewhat controversial, that thread is in the War Zone forum. Long thread, worth exploring.

My more recent post #174 has all the latest sources of good carnivore info.
The Just Meat link is a great start point, and MeatHeals has some amazing successes stories with details of what each person ate. Those links will give you answers to your questions.

Personally I also Fast, and that Dr. Fung thread is in Diabetes sub-forum. So to cover my bases on protein intake as an older woman, I often eat just meat and eggs in my eating window, but not exclusively. If I feel like a salad with steak, I'll add it. I feel great when I Fast and just eat meat, lots of energy, joints feel better, skin better...but what is most important? Is it the fasting or meat or both? And I have also felt great with a strict Dr Westman diet eating three meals a day (no nuts, alcohol, very limited dairy and added oils, and only 3 cups veg) You might try different combos and see what works best for you.
