This is good advice for your friends and family, but a bad answer to the question. "How can we solve the obesity epidemic? Stop eating so much and get some exercise." Well sure, but this misses the big picture. We built a social infrastructure that encourages a sedentary, solitary life. We shouldn't be confused by physical and emotional health implications. We can expect some people to be proactive about it, but we can't expect that of everyone.

No. Pro-exercise propaganda has been extremely strong for longer than you've been alive. Large parts of the economy is focused on exercise and health, and it is accessible to everyone.
But it sure feels better to think that every problem is "society's fault". That's the easiest and cheapest cop-out. Just takes a few seconds to type on the keyboard, instead of doing something.
I guess we need to delete the internet and tv from existence.
I think that the more people getting out and putting effort in the better, it helps create a knock on effect.
