My surgeon suggests Chike. I chose the vanilla but it comes in several flavors. It really didn't taste all that good to me so here is my solution:
In a blender:
pour 1 cup milk ( I use 2% or lower)
1/2 c ice
1/4 cup low fat, no sugar added frozen chocolate yogurt
2 scoops of vanilla Chike
mix and drink....
this cuts the strong vanilla taste while not adding alot of extra calories and without adding sugar!
