The nutritionist at my center said things like ensure, boost, and slim fast were just unacceptable because of the sugars, carbs and fat content. She said any protein shake that was made with whey protein was desirable and at least 20 Grams per serving of protein. She said try any brand as long as it meets that requirement. Also to try and keep carbs to 16 Grams per serving or per meal. I use Unjury as does Pat but have also used the EAS. She said if any of us were vegans she would make some different recommendations (none of us in that class were vegans though). Later on I talked with a friend who had RNY and she drinks the EAS that has like 43 Grams of protein. When I asked about that I was told that your body could only absorb or use about 20 Grams of protein at one time and that is why they want only 20 Grams at one time or per meal. I now get most of my protein from my food and drink at least one shake a day (either mid afternoon if I am home or for a bedtime snack). Sometimes when my band is tight in the mornings I will mix a smoothie and sip on that to get me going. 6-8 ounces of skim milk, one scoop of vanilla unjury, and I throw in some fruit like strawberries, blueberries, or one half a banana. Let it sit for a bit to get the air bubbles out. Unjury protein mixed with different flavors of crystal light are really good. I like orange sunrise and the fruit punch the best.
