The only problem is eating enough, I frequently miss my target of 3000 kcal, but I am simply not hungry much of the time.

If your eating fatty red meat (more fat then lean), and your not hungry - I don't think you need to hit a arbitrary calorie target.

If you have access to a body composition scale, as long as your non-fat mass is holding steady, I'm not sure there is any concerns at all.

I have noticed that my dandruff is way less, my skin doesn’t flake, I can focus better (not as good as meds but maybe 30% of the way there). I also dropped body fat a bit and gained some muscle, but I need to do that for other reasons too. Overall it is not an awful diet.

I'm also doing the zero-carb eating pattern, in addition to what you saw my shoulder injury went away (but comes back if i cheat), my tinnitus went away, and I don't get sunburned... weird stuff
