Mine wasn't really a secret.

When I first started this way of life almost a year ago I made two print outs that read:

Tempted? You are only cheating yourself.

I attached them to my frig and the freezer. Everytime I started to cook dinner, get a snack, or anything else it was an upfront reminder that it is ME that makes the difference on if I succeed or fail. If I failed to lose weight, it was me to blame and not anything else.

It's worked 46 pounds and still counting.
