First of all, Happy Surgiversary! Mine was May7th and I'm also a couple pounds below my goal weight. I have been concerned about losing too much, too and looking sick. My family and some friends have all said I look great as I am and not lose anymore or I will look sick.
Anyway, I went for my one year check up and my surgeon and NUT were thrilled with my results! They said I'm at a very healthy weight. I asked them what to do if I don't stop losing. They said to add things like cheese, nuts, protein bars and good carbs in general. They also said that I could start eating more of other foods such as vegetables and fruit etc at meals because it's not quite as big of a deal if I don't get all my protein in every day as I'm past the stage where I'm at risk for hair loss. That being said, they didn't say don't worry about it at all, just that a day here and there where I don't hit my protein goal isn't such a big deal.
