Resolution #3: Lose 5 to 10 pounds
This is by far the most popular resolution people make. The key here is to take it off, and keep it off for three months.
Let's start with the worst-case scenario: At the slowest rate, you only have to lose half a pound to one pound a month. That's 30 days to lose not very much weight. You can do that! Once you get started, you'll build momentum. At its fastest, you can probably take off all the pounds in two months. And it probably involves fairly easy solutions. (You know where you overdo it!) If you already eat a fairly sensible diet, just add more exercise. If you don't exercise at all, talk to your doctor about starting.
Why the three-month plan? In the resolution-keeping game, says Dr. Norcross, it takes 90 days to solidify a new behavior—like switching out that evening bowl of chips for air-popped popcorn.
