Sounds like a good idea to me - having a buddy with similar goals and ready to kick my butt is just what I need!
What plan are you following? To be more specific, I'm following the 4-3-2-1 food pyramid (4 servings fruit/veg, 3 protein, 2 whole grain, 1 extra calories) in the Bigger Loser book and so far, I'm happy with it. My main issues with this are binging. If I've had a bad day, I will eat everything in the apartment (granted, I try not to keep junk food in the apartment - but still, eating a whole bag of rice cakes isn't exactly healthy either - that's like, 600 calories! I know because I've done it. On multiple occasions.).
What I'm really bad at? Working out. I hate it. And I swear, the only reason I even attempt that Cardio Max Biggest Loser DVD is because I can pretend to punch Bob in the face during his kickbox sequences.
What do you, my new buddy, need pushing on?

I'd be happy to help!
