The shakes can cause some people to stall, so use with caution. As an occasional treat they shouldn't be to bad. I prefer the taste of the EAS ready made to Atkins, but thats a personal opinion

You might add a bit of heavy cream or something else to up the fat percentage. If you take psyllium husks you can throw them into the shake too to hide them, just make sure to not let your shake sit or you will have pudding.
