If you have a medical reason, verified by a doctor, you should be exempt from the tax.

But if you just eat too much, and/or eat the wrong foods, you should pay more for health care than those who are disciplined.

But the gov't should not be able to tax specific foods because they are fattening. Why? If the sugar lobby gives a candidate for office a million dollars in campaign funds (tacit bribe), what are the chances of a sugar tax? And what would be the chances of a fat tax? After all, sugar and fat equal flavor.

Since being obese makes your health care cost more, shouldn't the obese by choice pay more?
