I did not follow her diet, but I did try to keep up with the weight gain. I gained 60lbs. started at 140lbs (I'm 5'6"), and tried to eat a protein shake every day, but I have no idea how many grams or anything. My babes were born at 39w3d and weighed 6lbs 12oz and 6lbs 14oz.
I had them at 39w5d and I think I might have gained around 30 pounds. I was overweight to begin with, though, and had hyperemesis. I pushed the protein like crazy after 32 weeks after switching to a MW, on her recommendation. I think it really did help, my husband proudly tells everyone I kept them in so long because they were so well fed :
full time, single, slightly soggy WOHM to Juliet (12.31.2004 @ 36w5d) and Willow & Adam (2.22.2007 @ 39w5d, HBAC transfer) and... expecting my little womb warrior Eowyn Susanne in September
My guys were both 5 lbs 6 oz and were born at 36w1d. Both completely healthy and we left the hospital the next day. I gained 31 pounds. I read a little of the diet, but found that it made me feel guilty if I wasn't following it. So I just tried to make everything I ate count. I didn't eat junk, sugar or fast food. My snacks were healthy and full of protein. I made protein smoothies and just tried to get as much good food in me as possible. And also tried to drink as much water as possible.
