My vote goes for EAS!
I add a tablespoon or two of heavy or reg cream and mix the ready made shakes with a little cup blender tool (battery operated gizmo). I find them to be easy on the stomach, and taste pretty good. I can't stomach the atkins or other low carb canned ones (The soybean oil I think makes mae nauseous and they taste too sticky sweet)
Just my humble opinion. The Strawbery Cream flavor is great.
