I know I don't have a lot of experience with this kind of thing, but am wondering if that is everything you ate today, and if it is, where are your veggies? If you haven't been eating veggies I would definitely suggest eliminating the shakes, and getting your carbs and a good amount of fiber from the veggies.

I'm not at all familiar with the shakes, but have read where some things like that CAN cause stalls for some people.
