My doc is only making me do a 10 day liquid diet, and he says it's becuase of the diet we are restricted to. We are restricted to only 3 shake choices for the liver shrink- bariatric fusion- bipro or wegmans. Bipro or wegmans brand you have to add 5g of fiber too, and bipro is perfect for people like me who can't do aspartame or sucralose. We are allowed as much sugar fee jello, fat free broth, and sugar free drinks as we want, but are limited to one cup of caffeine a day, and none the day before surgery. We are also only allowed one 1/2 cup of nonstarchy veggies daily, so I will crunch on some carrots or toss them in broth to make soup.
Sorry for the long post, just trying to help.
