I think if you don’t crave the fish,your body doesn’t need it that much…and probably gets some from other foods.
Back when I was VLC Paleo I was craving&eating fatty fish daily,before I didnt even like fish…..and now eating with a more Peat-inspired framework I have no craving for fatty fish at all anymore,I never even think about it.
So,I’m guessing(yet have a hard time trusting) the body knows which foods it wants for different nutrients and adapts quickly to a certain dietary framework to get everything it needs?
