The 2007 National Body Challenge has begun over at Discovery Health. They offer customized meal plans, expert fitness and weight loss information, chances to win $1,000,000 (cough. there’s some motivation!) and a free health club pass. They also have assessments available, if you just want to see where you are from last year. 
I signed up last year and there’s a ton of really great info there - plus the before & after pics are pretty motivating!
