I generally enjoy Jimmy Joy's shakes and I think it is a good way to have a complete meal in case of emergency. My favorate flavors are vanilla and chocolate; I tried others (banana and apple with cinnamon), but they didn't hit the mark for me. However, they are not a sustitution for a healthy diet and after having one I feel hungry after a short period of time. This is an issue for all these kinds of shakes, regardless of the brand. I normally drink a shake to substitute dinner once or twice a week and it works fine for me. Nevertheless I enjoy the shakes of this brand, if you buy the powder it is way more budget friendly than any of the shakes you will find in the supermarket.
