Part 1: LOSING the last 10 lbs.
Only do it if you are willing to do part 2. If you are, I recommend MWL. Or regular plan, if you've been on it up to now, but with less bread, more veggies, etc.
Part 2: KEEPING OFF the last 10 lbs. Stay on what got you there. If you lost via MWL and you return to the regular program you will probably gain it back. If you lost on the reg program and you start adding in non-plan items, you will regain it.
Basically, you can't expect to get to goal weight, esp. if it's a number that is harder to reach for you, and go back to anything OTHER than what got you there.
Hope that makes sense!
