Well, if getting back to the OP is hijacking this thread, then here goes…
As the other posts in this thread have already pointed out, what “society” embraces as the ideal image, as illustrated by popular media, constantly changes. But the constantly fluctuating images in the media are not the source of our problems, they are the manifestation of them. We are constantly grapling with self-doubt in the face of our successes, mentally re-working our own self-image, trying to find what ‘works’. And the media facilitates this.
I don’t think I am out of line saying that the “ideal” women of today are a far sight healthier looking than Twiggy. Indeed, I don’t think there is any shortage of fuller figured women in contemporary media than in the past. Christina Ricci, Jewel, hell even Anna Nicole Smith are not suffering, nor is Monica Lewinski. Geri Halliwell gets panned for LOSING too much weight. Female athletes are enjoying increased celebrity as girls are flocking away from exercise in record numbers. In addition to being intolerant, we seem to also have developed a very sharp sense of irony.
I think that Western societies are less tolerant of obesity now than in the past. And for good reason. Obesity (and I am not just talking the proverbial ‘few extra pounds’) is akin to lung cancer from smoking - a (very frequently) self-inflicted condition that can be mitigated by the afflicted individual, but most frequently is not. Being overweight is unhealthy. As medical science learns more about the effects of obesity on health and longevity, it becomes clearer that mass is inversely proportional to life span.
Add to this increased knowledge the tragic fact that chronic obesity in North America is actually increasing. No matter what TV tries to tell us, as soon as we drop back into the real world, we are confronted with it. And if that isn’t enough, North America has given us the greatest contradiction of all - obesity combined with malnourishment. A stead diet of ho-ho’s and Tab hasn’t been kind to us. And people can’t help but notice.
So what does society do about it? Put our knowledge to use? Teen pregnancy is reviled today, where as a few short generations ago it was expected. Smoking causes cancer, and has garnered quite the stigma. And now our knowledge of the effects of obesity has created a yet another stigma. Yet unlike teen pregnancy and smoking, which have decreased since the 1950’s, obesity is on the rise.
Sadly, in the case of obesity, not all cases are preventable. Some conditions exist which simply pre-dispose an individual to weight gain. But these people make up a very small portion of the population. The simple fact is that with all our successes in the west have come a myriad of excesses. In light of all the knowledge that we flaunt, the wealth we possess and the moral high-ground we take at every opportunity we seem convinced to put our knowledge behind us in favor of apathy. Unlike smoking and pregnancy, preventing obesity requires an action rather than inaction. And we have gotten very good at being inactive. While it’s intolerance we are projecting, I have little doubt that it is frustration with ourselves that we feel. We know it’s preventable, and we have the ability to do so. Yet we don’t. And that’s what really burns.
