Not eating enough

So I've hit a bit of a plateau and decided to take Weight Watchers up on their free trial offer. I posted on the board that I felt 32 points was too much because it'd be more calories than I eat now. I was quickly told that obviously what I'm doing is no longer working, probably because I'm not eating enough for my body to keep going. I find this hard to believe because I don't feel that I'm not eating. I even made myself start snacking. I think I need to eat more at breakfast and less at dinner. This is my plan for the next week. I'll let you know how it turns out.
