In response to a reference dropped in a comment on a private entry.
This book does not argue that there is no relationship between weight and health. It argues, rather, that the health risks associated with higher-than-average weight have been greatly exaggerated, while all sorts of related but far graver risks have been ignored. In particular, this book emphasizes that poverty, poor nutrition, and a culture that makes it easy for Americans to be sedentary are important public health issues in America today. We should be encouraging Americans to be physically active, to eat well, and to provide reasonable access to medical care for those among us who lack it. What we should not be doing is telling Americans that they will improve their health by trying to lose weight. As we shall see, there is very little evidence that attempts to achieve weight loss will improve the health of most people who undertake them, and a great deal of evidence that such attempts do more harm than good.
The point that I feel is relevant from the entire shpiel shows up clearly only at the end. There’s a great deal of finger pointing and moralizing being done by someone who is condemning finger pointing and moralizing.
Rising technology has led to some problems. Ready transportation and mechanical technology reduces the exercise that the average person puts forth. Great rises in agricultural productivity increase the ready availability of food. Taken together, these trends lead to both a decline in health and increased quantities of body fat.
Some people stay physically active. Another, partially overlapping, group of people consume similar quantities despite the increased availability. Some do both, some do neither. And some adopt unhealthy behaviors such as anorexia in response to the perceived pressure to “eat right”.
I did find the article to which you linked interesting. I also found it harshly critical with few references to back it up.
I do not advocate turning back the technological clock. That is ridiculous. However, we can work on incentives to encourage and facilitate increased athleticism while discouraging and de-incentivizing the consumption of “unhealthy” or highly processed food. There are things we can all do on an individual basis to make it easier for ourselves as individuals, but as this is a systemic problem, I think a systemic response is more appropriate.
If one in a thousand people is doing something we’d rather they didn’t, personal character may be a reasonable explanation. If two out of three are behaving in detrimental fashions, perhaps other explanations, and correspending interventions, are called for.
