? Insulin is not about management of hunger. I think you got your hormones mixed up.

But yes, meat and vegetables is basically what I'd recommend. Never pasta or bread or sugar unless you need help gaining weight.

Meat and vegetables would make me sedentary from having inadequate glycogen for physical work and exercise.

How about: some pasta and bread to enable physical exertion.

I know a guy that has had meat only for 3 years now. Most fit guy I know.

My father and I have avoided carbs for a few years now. Can do home renovations, gardening, dirt bike riding, and hikes better than we ever did eating carbs. Unless you're doing long distance hikes/running/hard core sports, I really don't think that's true.

He’s probably thinking of ghrelin (or NPY), but leptin and insulin both act as satiety signals too, although weaker than the hunger signal.
