What's the big deal, put the calories of the dough, sauce and cheese for each size (12, 14, 16 inch) then list the toppings and the calories of each, the consumer can do the rest an add it up. I suspect this whole thing has to do with keeping trade information private, as if you could. Know how many calories of peperoni they have on the pizza, you can convert it to weight. Same for dough, cheese and sauce.
And $3,000 to $5,000 per sign? I calculate the calories of every meal I make, it takes 5 minutes and I do it on a computer so I could print it out for nothing. I'm a Reagan Conservative but I agree with the feds on this one, I use these charts in Subway, fast food places (if I can find them).
Additionally, this has uses beyond dieting. I'm a type II diabetic and must limit my intake of starch, American style pizza is almost lethal to me, but, a good New York style (0.8 Thickness Factor) is just fine. I would like to know how many calories of starch are in a slice of their pizza just to see if I can have more than 1 slice. I almost set a record on blood sugar after eating Jets one night.
