Would it be so bad to ban advertising for unhealthy foods? Anybody who wanted to eat them would still be able to, they just wouldn't constantly be bombarded with the temptation when they may not otherwise have been thinking about it.

I'll reply with a popular joke that should apply to the three current replies about "why would that be bad":

"The doctor told me to stop drinking, smoking and having sex. I asked him if it would make me live longer and he said: no, but the time will feel longer."

So just optimise for what you want, but forbidding these sort of things forces others to leave the same dull life you want to live.

Right, but forbidding advertising them is very different to forbidding them. The idea is to allow people to make a freer choice about what they truly want rather than being influenced into doing them.

Indeed. Instead of seeing it all the time and getting unhealthy due to this, i would only get it when I think about it.

I'm lost on why you don't like that? Do you stop buying sugar water if the stop advertising them?

In all seriousness, i would prefer that. Good thing that at least some countries have added taxes on sugar.
