I refer you all to Gina Kolata's "Rethinking Thin".
From Publishers Weekly
Starred Review. New York Times reporter Kolata may be the best writer around covering the science of health. Here she offers an eye-opening book that questions all our received wisdom about why we get fat and the health hazards of those extra pounds. In chapters equally entertaining and dismaying, Kolata (Flu) traces the history of dieting fads back to the 19th century; discusses our changing ideas about the ideal body (thinner and thinner); and, most importantly, explains how genetic and biochemical understanding has (at least among researchers) replaced the view of obesity as a lack of self-control. Most dramatic is Kolata's recounting of Jeff Friedman's groundbreaking search at Rockefeller University for the "satiety factor," a hormone he called leptin that tells our brains when we're full. The science alternates with moving chapters in which Kolata follows a group of people in a weight-loss study who are trying desperately to get thin—a quest that, as Kolata makes increasingly clear is sadly futile. In her final—and perhaps most surprising—chapter, Kolata blasts those in the obesity industry—such as Jenny Craig and academic obesity research centers—who are invested in promoting the idea that overweight is unhealthy and diet and exercise are effective despite a raft of evidence to the contrary. This book will change your thinking about weight, whether you struggle with it or not. (May)

HC, This is ignoring an elephant (no pun) in the room, while looking at something esoteric that people will use to support the claim that good diet and exercise is futile. What I'm about to post are somewhat old stats I had from some work I did.
We have an obesity epidemic in the United States. 58 million people overweight. 40 million OBESE, which means that it is not just the few extra pounds and an unrealistic body image problem that society has thrust on people. Eight out of 10 people over the age of 25 are overweight. 78 percent of Americans don't get even the most basic levels of activity to promote good cardiovascular conditioning. A quarter of the population is completely sedentary. And we have seen a 76 percent increase in Type II diabetes in adults 30 to 40 since 1990. 80 percent of the diabetes we are seeing is related to obesity. 70 percent of the cariovascular disease we have seen in the last 50 years--a similar epidemic--is related to obseity. 42 percent of breast and colon cancer that is diagnosed is among obese individuals. 30 percent of gall bladder surgery is related to obesity. 26 percent of obese people have high blood pressure, which contributes to a host of health problems, including potentially, stroke.
It's horrifying when it comes to children. In 1982, 4 percent of American children were overweight. In 1994, it was 16 percent. By 2001 it was 25 percent--or a quarter--of our children. The numbers are sadly much higher when it comes to minorities. 33 percent of African American Hispanic children overweight in 2001.
In 1979, hospital costs associated with childhood obesity--forget the billions adult obesity is costing us and taxing our health care system, I am just talking about children--amounted to about 35 million. In 1999 it was $127 million. Today, it is even higher, although I don't have the number.
In children, again, those one in four overweight children are showing early signs of diabetes in most studies addressing it. It is a health epidemic and we are doing it to ourselves. 60 percent of those children alrady have at least one risk factor for heart disease.
As recently as 1990, 4 percent of childhood diabetes was Type II. That number has risen beyond 20 percent.
I could go on and on. So looking at some obscure book that looks at a study on leptin and then concluding that people can't help themselves to live healthier by dieting and exercise really misses the point, in my opinion. They can. Leptin and satiety factors aren't the problems for all of those obese people, who have become more and more obese over the last 50 years. The fact that they eat unhealthy and don't exercise enough is what accounts for it. The health problems and the costs associated with them that we've seen are self explanatory.
It's really as simple as most people not wanting to face obvious truths. That pint of Haagen Daz is not good for you -- especially when you are eating it all the time. That fast food is not good for you -- especially when it is a great deal of what you eat. That box of twinkies is not good for you. And not getting enough exercise is not good for your body. People KNOW this intuitively. They just have lived increasingly lived lifestyles contrary to what they know intuitively, because the fatty foods taste good and are almost like opiates. It's a hard habit to kick. And it's hard work to run and lift weights and exercise every day. It's easier to sit on the couch and play X box while blowing through a bag of Doritos. That's a generalization, of course, but when you are seeing obesity numbers skyrocketing the way we have, the generalization is not completely out of line. It's behavior related, not something beyond most people's control.
