Ok, so it's been well established that in our society's transition to a more sedentary lifestyle we've become a more obese people. This has caused all sorts of health problems; in fact, many of the most common health issues plaguing people today have to do with the fact that we're all just fat.
Now, the usual response is something like "we need to get less fat. Be more active, eat healthier, blah blah blah"; we all know what we need to do.
But here's my question: what if we didn't? Say we just decided we like our sedentary lifestyle, our culture of obesity, and therefore we decided we'd just live with the health risks. What would happen to people - humans as a species - if we decided that's what we wanted to do? Would we evolve to the point where being obese (by modern-day BMI standards) was no longer a health risk? Presumably there could be mutations which would allow bodies to handle fat or cholesterol, or whatever in a way that is not unhealthy. And these mutations should allow people to thrive in a sedentary culture, without the health risks that others face, thus eventually, over a long period of time, leading to a new type of persons, for whom obesity is not a health risk. They could be fat (by our standards) without any of the traditional health risks attached.
Could this happen realistically? I mean, people have certainly evolved over time, because of pressures from nature. But could we evolve because of cultural pressures? Have we in the past? I think this is fascinating stuff. Of course, I'm all for living a health life style, and would never advocate this type of idea as a solution to our world's obesity problems, but still, it's just kind of neat to think about the potential, right? Thoughts?
