I watched the film 'Land' last night which follows a woman who moves into a shack in the wilds of Canada (I think).

She was mostly eating deer/rabbit which I believe are very lean, along with a bit of fish, berries and later veg.

Got me wondering if a mainly protein diet (incl. liver) can be healthy.
(To me, it seems more natural/realistic/doable than LCHF).

Thoughts?
