I went nearly pure carnivore about half a year ago, having been low carb for well over a decade before that, and at least my very well in control during the previous decade type 2 diabetes seems to have pretty much disappeared, at least when you are talking about blood sugar readings. And high blood pressure is nearly gone too. And my excess weight seems to be disappearing nicely with no extra effort from me, I haven't even exercised all that much during the last year (although my job requires being mostly on your feet so I do get some).

And just from that low carb - all the doctors I have seen always think that I'm a heart attack waiting to happen, due to family history and excess weight and age and high cholesterol, but two years ago I was checked very thoroughly. No hint of plaques or stenosis in my arteries and heart works quite well. So yeah... they still constantly try to push that more "healthy" diet with lots of veggies and vegetable oils and avoidance of meat and animal fats on me every damn time I see a doctor.
