thoughts on trimming down

I have been having thoughts of trimming down lately. I think I now belong to the obese category if I'm going to calculate my body mass index. I know that I should loose weight because it is not healthy anymore but I just couldn't resist eating! I know that I should loose weight if I want to get pregnant but I just can't stop munching every sweet desserts that caught my eyes. I'm trying the no carbo after 6pm. Hope I make this one work!
