I don't have first-hand experience with them, but if they're the same as these , there doesn't seem to be too much value with them. A day's "serving" is only 240 calories, the vitamins are pretty much what you would get from any multi-vitamin tablet, and 4 grams of protein isn't a lot if you're at all active. And I honestly can't see how they would be filling.

Seems to me you could be doing the same thing, only better, with a vitamin tablet and a trail mix made up of M&M's and peanuts.
