I think you are right in terms of the ultimate effect (more weight gain). People are already taken in by the various psuedo-mythologies concerning fats, and so they will be scared into eating more empty carbs. Somewhat orthogonally, I think the government is overstepping its bounds. That said, as someone who actually has a reasonable idea of what is "healthy," I'll be quite happy see what is in the food I may or may not be ordering. Say, for instance, what kind of oil is going into a salad, or searing some fish...
