For a mom on the run (who'd like to lose, say 5 pounds), these South Beach snack bars are pretty good! I used to buy Quaker Granola bars, but in comparison I found them too sweet and not filling enough. The South Beach bars have a higher calorie count but also much more protein and I do find they keep me full much longer. I don't regularly use them as meal replacements (it's more like I pop a few in my purse when I'm going somewhere and don't want to be tempted by fast food), but I can well imagine that they'd do a decent job.

I haven't tried that many flavors yet. So far, Chocolate is my favorite. The only complaint I have is that they are quite expensive, especially compared to Quaker :(
