The doctors do not make tax policies. Doctors thought it would be cool to give twins various diseases to see how different treatments affected them. Doctors should not be making choices on liberty. They should operate within the constraints of liberty for all.

Also in the UK the gov. pays for our healthcare, obese people suffer more ailments so the government pays for there treatment, if they need a mobility scooter, benefits if they can't work, help in the home if they are severely overweight. So by reducing consumption of unhealthy foods they could hope to reduce expenditure in some sectors and increase elsewhere.

This is exactly the mentality that nationalized healthcare brings, and is the basis for my argument here:
[link]You proved my point with your statement. Nationalizing healthcare gives government the power to dictate the free rights of individuals to live how they want when it only should be effecting themselves. Moreover, you place a few non-elected people (board of doctors) responsible for restricting the liberty of everyone.
Again, why stop at fast food or soda? Why not make the one approved diet for all and any wavering is unlawful? Why not make sofas illegal? Your television only works for 30 minutes a day. You only get 30 minutes of video games and 15 of those have to be brain-enriching puzzles. Homosexuality is gone. In fact, sex at all is gone unless it is at a government approved lab and can be monitored so disease transmission is minimized. Cars that go over 40kph will be outlawed so traffic accidents will go down.
People should have the liberty without penalty to choose what they want to eat. People should have the liberty to sell whatever food they want without unfair taxes being levied on their business simply because uptight liberals don't approve of your choices. Making the individual responsible for their health makes the liberty of their own choices reasonable.
