I agree with Jan. Find a way of eating that you feel you can do, hopefully, for the rest of your life. After you've done it for 2-3 months, you can reevaluate and decide if a change in plans is the way to go. I've heard from others that they were doing Atkins in the beginning because for them that was the quickest way to lose weight only to change to a different plan because it fit with their life much better. Check out the sucess stories section. Lot's of great inspiration there and lots of people here on many different plans.

Good Luck!
