Consistency/Smoothness = Good. This is a pre-made shake so it's very well blended. One lump.
Protein Content = Good. The pre-made high protein slim-fast has 20 grams of protein which is considerably higher than their mix.
Smell = Higher protein equals weird protein smell. Hence, the yuck.
Taste = Passable. Sort of a weird, watery, overly sweet taste. Who started calling these things shakes? Thick, brown water is more like it.
Overall rating = Not awful, which for a protein shake may in fact be high praise.
In the interest of full disclosure, I didn't do so well with my protein shakes over the weekend so the taste test challenge lapsed. Back on the wagon today. Real pre-op protein shake diet starts Sunday.
