I should add that onThanksgiving, my brother and I both te the same turkey dinner and he checked our blood sugars an hour later, as he is diabetic and doing keto for that as his doctor recommended. My sugar was 130 and his was around 430. He had been doing some kind of high fat snacks too along with eating mainly meat.

Now he is on some kind of injection that makes him really sick but he has lost quite a bit of weight.

To be fair, he is much more sedentary than I am.
