Why should the government get in our lives you say? Well, if we don't take care of ourselves, we cannot work hard. If we do not work hard, firms cannot make money. If firms cannot make money, they piss and moan to the government so the government has to do something about it. That involves getting into our lives. Plus, getting into our lives is profitable (taxes), and not doing so loses money (income tax, as well as has to pay out money if you can't feed yourself).
On a separate note, higher prices WILL reduce the amount consumed overall, at least if you believe in mainstream economic theories. On a personal basis, sure, if you are rich and a hardcore addict, then you probably would not cut back much, if at all. But the poorer, less addicted group of people will. By how much is determined by the price elasticity of demand, which depends on how reliant you are, how much of income is spent on the good, time period for consideration, etc.
Shouldn't you (not you specifically, just people) be smart enough to decide between unhealthy foods and healthy foods? If so, then why do we need some bureaucrat in some cubicle to decide what we should be able to eat?
As for firms not being able to make money, companies fire unproductive workers all the time. You ate too much McDonalds and you've gained 50lbs which has made a negative impact on your productivity then you'll get fired. You don't have to worry about firms not being able to make money.
The only real argument from this avenue is that obesity leads to an increased strain on the health care system which raises the costs on everybody. A better alternative to taxing such foods is to tax obesity. Put a $1,000 tax on all obese people but, give healthy (a.k.a within a certain limit of BMI or similar scale) a tax break of $500. We could also extend that idea towards smokers. Just a thought
