Soon it will come to how many calories you are allowed to purchase. Any over that and you either pay a sin tax or are not allowed to have it. But the “sin” tax is the logical alternative, since Liberal/Socialism needs increased revenue to come up with more ideas.
Like Cap and Trade, you could also be able to purchase additional calories from someone who eats nothing but uncontaminated vegetables (No dressings) and drinks government approved water. The possibilities are vast and unlimited for the future of Liberals and government.
The logical next step was food. Now they're ramping that up. Amazing how many Freepers seem to be in agreement with them.
One can't control one's own eating habits so one has to have the Gov't help regulate one's own passions.
