I saw a new NutriSystems ad the other night. It has some plan for diabetics. Not sure if they're targeting Type I or Type IIs but it doesn't really matter. They make the claim that following their plan can lower your a1c by .9% They mention this several times.
So the math problem is: If your last a1c was 10.0 (to make it easy) and you followed their plan and it worked as they say (and that was the ONLY THING to affect your a1c), what would you're next a1c be?
Submit you answer and show your work (just kidding).
I think I know the answer and just want to see if anyone else concurs ... I'll also explain why, if I'm right, it seems to be deceptive.
