Pre op diet

SO im on the liver shrink diet.... I was curious, why arent egg beaters on this menu? theres no carbs, no sugar no sodium just protein and only 25 calories per serving... anyone have any ideas?

All pre op diets are different. Some are all liquid, but mine is less restrictive. I am to have three protein drinks a day and one "real" meal consisting of 4oz lean protein, 2 c selected veggies, one small serving of dairy, carb, fat on the list. I am allowed egg beaters on my program.

The idea is to get your liver to do as little as possible. I seem to remember egg whites being on my pre-op diet. But egg beaters must have something other than eggs in them.
