Muscle milk
I have the powder. It was super expensive (in my opinion) but it taste really good. I was impressed. I don't like any protein shake i have ever tried and it kept me realy full. I also put a scoop of pb in it. Our dr said the powder is much better than the pre mixed. We also use skim milk instead of water.
This is my opinion...if you drink it in place of one meal and this does not cause you to eat more, I don't see a problem with it, but if you were to do shakes for all meals, then you are using liquid calories to get your meals and this is not how the band is suppose to work. Sometimes I just don't feel like eating but need the energy so I will have a shake but my next meal will be a dense protein meal.
