babe, you're fooling yourself alright.

No diet will work in the long term if you have this idea that you can return to the diet and lifestyle that made you fat to begin with, and not gain/regain weight. Think about it.
No diet will work in the short-term, if you make exceptions for your favorite indulgence and continue to indulge.
Cut out the m&m's.

(I know, NOT what you wanted to hear.)
