Depends on the quality of the fat, you want high Omega-3 fats, not omega-6. Get them from the SMASH fish (Salmon, Mackerel, Anchovy, Sardines, Herring), and grass-finished beef, and avocados.
Agreed. But a lot of the Keto promoters push fats from beef and pork. I got no problem with fish. I have always enjoyed fish of all kinds. Except squid. And Urchin.
