can i use meal replacement shakes

Can I use meal replacement in place of protein shakes? Thank you 

You should check with your surgeon or nutritionist.

If you mean HMR or Optifast or Medifast, those might work.

If you mean ensure, or others, they may be too high in sugars and calories and too low in protein to be ok.

It may also depend on which surgery you have.

Most regular MRS have to many sugar and not enough proteins specially at the beginning of our post op diet.  I can tolerate up to 10gr of sugar in real food - dense foods, but 5 gr in liquid form makes me sick most of the time. 

Yes, as already indicated, it depends on which one, but very few of them are going to provide enough protein at an acceptable calorie level.

• My program called for three weeks of sugar free carnation instant breakfast for three weeks before progressing to pureed foods.  After that, protein drinks were OK.

if you know someone who is a consultant for Isagenix, their Isalean shakes are similar nutrient composition to diabetic boost, except higher protein. they also have isalean pro which is even higher protein (36g/serving). that's probably a good meal replacement shake option. no artificial sweeteners and low GI.

If they contain the protein you need and not too much sugar, I don't see why not.
