Well, I am on my pre-op diet of Slim Fast 2 times a day at 3 oz. mixed with 1 oz. of skim milk twice a day. Then one 350 calorie meal or lower. This is a 2 week pre-op diet to shrink the liver. Not bad, but hungry now and again! Smart Ones, Lean Cuisine, and Healthy Choice have become my BEST friends, lol!
