There's always ye old rice cakes..blech. I lost 45 lbs in a bout 3 months using a program called Isagenix. Healthy, no side affects for me, and they have several prepackaged snack options that don't have to be refrigerated.
Some of those snack options are very similar in construction to candy bars, but they are a little blander than candy bars. The side affect of the "candy bars" is a compound that helps curb the need for the snack.
I've been off the program for about 2 months and I haven't gained the weight back either.
My tu cents.
