My hypothesis is increased consumption of fat and decrease in physical activity.

I don't disagree that cheaper and less healthy food has become more abundant if that is what you are asking.

OK. Cool.

We
might be.
I say that the cause is to do with people not considering the
total (monetary, non-monetary, direct and indirect) costs of eating "cheap unhealthy foods" (as well as getting less exercise) and therefore making poor choices about diet and exercise.

No I don't. I think corporations primarily respond to customer demand.

Yes. That is the responsbility a corporation has to its investors.

If, as individuals, we choose to let them, yes. But again...the reason some place like McD's sells a gajillion burgers a year is because people
want to buy them. As soon as people want to buy a gajillion salads a year, that's what they will sell.

In the long run people will see the ill-effects of eating high fat and sugar foods and getting no exercise and choose (if it is important to them) to change their buy, eating and exercising habits.

I think we see it happening already. Not for everyone mind you. But for many indeed.

I take the approach that people should be free to choose to eat what they wish. I take the approach that no one has the right to force another to eat (or not eat) some particular thing. I take the approach that we will (and do) have people (outside of government) that are concerned enough about these issues research them and to inform all of us about them.

Of course I care. But I don't consider it my right to tell people what to do.

Influence? Probably. But really only to the extent that we
choose to be influenced.
Control? Not so much.
Bottom line? People are not generally
forced into the choices they are making. They are
choosing them
freely.
Those that are greatly concerned about those choices are free to use their freedom of expression to inform and educate all of us about the risks and then we can all make better informed choices (if we
want to). I am also free to actively educate and inform myself (and family and friends). But I am not free to force anyone (well...I guess I can
make my kids eat their veggies before their ice cream

) to do anything about it.
