One of the nice things about products like Jake is that they have a verity of applications.
Personally, I eat Jake as an aid to weight management. I love the certainty of knowing I have had enough when I have had my three Jakes. Sometimes the monotony makes me fall off the wagon though.
Sometimes I add unsweetened coco powder to jake, which is delicious.
However, I find I miss savoury flavours. It would be awesome if there was a way to give Jake a spicy or tomatoy flavour but I don't think that would work given the overpowering sweet vanilla flavour...
