I am considering VSG surgery, and I want to know if I will be able to continue to drink Green Smoothies (greens and fruit in blender); I drink one every day and don't know how to live without them! Also, I want to know why the surgeons say people lose 70 - 80% of their weight. I don't want to do something this drastic unless I have a chance to lose all my weight! (53 year old female, 150 lbs overweight). And do I have to do protein shakes? I hate them...but love greek yogurt. I am willing to do some things I don't like of course. I have tried everything and am tired of being obese.
