A cousin NP suggested pea protein as easily absorbed by the body. If you can get a smoothie down, try pea protein. Brand does not matter as long as nutritional value is there. I used Arbonne FeelFit Pea Protein Shake (Chocolate) together with Arbonne Essentials Green Balance (for other nutrients). The protein power also comes in vanilla, but chocolate helps mask the taste of the greens powder. To start, I had 1 smoothie in the AM, and one in the PM. I did this for a couple of days and found it stopped the weight loss and helped me put on a few pounds. It was almost like a 'reboot' and after a few days I was able to eat more of other foods. I still have the powder, but have only had to use it a few times since the initial reboot, if my weight gets too low. I find if I can put on a couple of pounds, eating in general becomes easier. Ice cream, cakes, cookies help maintain weight.
