mhaeffne, I was so grossed out by meat (since childhood, no ethical convictions just always made me gag).
Seafood (fisha and shell fish) can absolutely make up the bulk of your diet. Shrimp has more protein than most other meats. OTB posted a breakdown of protein amounts and shrimp was near the top! As well as scallops. So keep on eating your seafood.
Make fruit and nuts the supporting roll not the star. As in I add some chopped mango to a thai shrimp mango salad for lunch, and some toasted pecans.
Chicken's flavor is mild, like many fish. Dry chicken is inedible imo, so make sure you go for bone in skin on thighs, or whole chickens. Primal sauces to help with the transition would be anything from a simple tangy hollandaise to a spicy coconut milk curry.
Do you like bacon? (I mean, who doesn't like bacon!!! lol)
The more I see the less I know for sure.
