Do an expectation check to be sure you aren't looking for a Norman Rockwell Christmas when life's dealt you something from Salvador Dali. Make a contribution to an organization that feeds the hungry. Then, when passing up a treat, you can be secure that somebody else is getting a little something extra to eat on your behalf. Set reasonable goals for your weight. The weeks of Christmas and New Year's are not good times to try to lose weight.
Success breeds success.
And don't stop weighing and graphing. Spread the word. Let people know you're trying to manage your weight, and ask them to help. Portion off a small serving for yourself. Then get the rest of it out of reach and sight.
