It's a mix of all of the above. Another factor is the amount of jobs that are sedentary vs the amount of jobs that are active. When the computer boom hit, it created a huge amount of sit on your ass all day jobs, (programmers, help desk, tech support, etc) so instead of bricklaying, etc, you became a desk jockey.

Also, technology advanced to the point where so much stuff is automated, it's not "hard labor" anymore (unless you work for Kathy Lee.)

But yeah, all those things are factors, the main problem is that our kids aren't outside all day anymore, their inside playing video games and watching TV. THe mom and dad are tired from working, (desk jockeys get mentally exhausted) and so they veg in front of the TV. Only a small percentage of people actually "work out" to stay fit, so you get obesity in huge numbers.

Actually, I am one of these obese people (I have PCOS, so that makes it harder, but not impossible to lose weight), and one of my resolutions this year isn't to lose weight (I'm just over 300lbs now and 6'1) but to do SOMETHING for a half hour, 4 days a week. Walk, swim, exercise, whatever. I'm not going to diet, I already eat as healthy as I'm going to, but I'm resolved to get up and move my fat ass for 30 minutes. We'll see what happens.
