Here's how I figure:
2,000,000 people ate an almost 800 calorie breakfast.
For the sake of argument I'm assuming that such a breakfast will cause most who consumed it to have exceeded their daily calorie needs by at least 400 calories.
2,000,000 x 400 calories / 3500 calories per lb = 228,571 lbs.
Oh, and each free breakfast also provided the recipient with more than a day's worth of sodium (almost 10,000lbs of the stuff for the nation!).
Thanks?
