NUT and Protein shakes

I am 6 months post op as of today, and I still do protein shakes.  I found that I lose quicker when I consume around 800-1000 calories.  The only way for me to do that and reach a 60-80 grams of protein is the shakes.  I stopped coffee and was really missing that taste.  I have been drinking the Atkins Advantage Mocha Latte protein shakes and I'm a very happy lady.  HW 399  SW 339 CW 236
