I followed the Brewer Diet (as closely as I could, that is A LOT of food) last pregnancy and gained 30 pounds, birthed a 7 pound, 4 oz baby. I had virtually no swelling and aside from pelvic alignment issues, a pretty comfy and healthy pregnancy. I also combined it with Weston A. Price principles: FCLO, butter, coconut oil, sprouted/feremtned foods, bone broth, etc...I have NOT had a model diet this pregnancy, but I'm working towards it. I usually follow the Weston A. Price diet, but have fallen off the wagon this summer and boy do I feel it!
I found in order to have a decent protein intake, I need to have a heavy-hitting breakfast. I end up eating lots of ricotta cheese, cheese sticks for snacks, a glass of milk when I first wake up then another before bed. I also have been adding a tablespoon of Great Lakes Gelatin to my herbal tea, along with a tablespoon of coconut oil, because I want to avoid powdered protein. And canned wild salmon is a friend, too, if you can stomach just seasoning it and eating it out of the can. Thats 30 grams or so right there, in one sitting! Sprouted bread has 6 grams of protein and is digestible, so a piece of sprouted toast with nut butter was great. If you can't comsume a hearty amount in one sitting, the suggestion is to eat a bite of something protein rich every hour (i.e. a cube of cheese, a spoonful of nut butter, etc....) I also have to rely on lots of Paleo-stlye muffins because of the heavy reliance on eggs in the recipes.
I have been taking dessicated liver because I just can't get the organ meats down right now. I don't know if it contributes to protein in dessicated form, but I like knowing I'm getting the health boost when my taste buds are shouting, "No!"
