New Year's diet 

A diet that one begins after New Year's Day. A person can either go on a New Year's diet as part of a New Year's resolution to eat healthier and/or lose weight, or simply for the purpose of losing a few holiday pounds. New Year's diets generally work best when combined with frequent, intense exercise.

I've probably gained five to ten pounds since Thanksgiving, so tomorrrow I'll be starting my New Year's diet. That means zero meat until February, as little junk food as possible, and medium-sized portions only. I also plan on hitting the gym at least three times a week.
