OK, let's try to have some information.

They are attempting to ban trans-fats statewide, as I believe NYC has done. Here's the AP story:

While there's a lot of varied opinion about this, it's clear that we would all live better lives without trans-fats, there will still be plenty of fast food, and we'll all still be able to get fat.

Hooray, Pocky and Shika!

The abolition of trans-fat is sometimes connected to weight issues, too, but I'm sure you're right that this is what dragonflye heard.

Still, reducing the number of fast-food places, or rather, reducing the growth of the number of fast-food places, is hardly the same as outlawing fat.
