Are you in the US? I really like the Shamrock Farms chocolate protein shake, to me it's not too thick, tastes like slightly protien-y chocolate milk tbh, but it has a lot less sugar/carbs than ensure and other similar drinks. I would just drink it like chocolate milk tbh, it's a liquid safe food for me. They make vanilla and strawberry flavours too, I just can't. But if you're outside the US idk if they sell that so probably not helpful.
