    Obesity

    The rapid rise in the prevalence of obesity in recent years has been described as an epidemic. It becomes a concern all around the globe because of its implications for the health as it increases the risk of many diseases. In addition to its health impacts, obesity leads to many problems which are felt by all levels of society from individuals, to families, and to governments.

Text A

    Our Big Problem: obesity

    As obesity is spreadingand eating away at America's economy and

    health. Theodore Dalrymple reflects on how society can bite back These days, it seems, almost everyone has a habit that he can't control. For millions of people, this habit is overeating.

    Never have so many human mastodons bestridden the earth as now. At

    one time, not so very long ago, such mastodons were rare enough to be curiosities, charitably thought by others to be the victims of their "glands."

    We had such a fat boy at school: His cheeks were so adipose that his eyes

    had become mere slits. We thought that he was ill rather than a member of a cultural avant garde.

    In America, more than a third of the adult population is now obese (obesity being defined as having a body-mass index more than 30). This is nearly three times as many as in 1960, and half as many again as in 1990. But the increase has been greatest among those known as the morbidly

    obesethat is to say those with a BMI of more than 40. As a proportion of the population they have increased in America by more than six times since 1960, and three times since 1990. They are now about 6% of adults.

    The cultural meaning of obesity has changed at the same time. For most of human history, fatness has been a sign of prosperity, of having risen, socially and economically, above the day-to-day struggle to obtain enough to eat. But sadly now, in Western societies, obesity is concentrated among the poorest and least educated. In America, blacks are 50% more likely to be obese than whites, and Hispanics 20% more likely.

    I once saw the change in cultural meaning of body size happening before my very eyes, when I practiced briefly in the mid-1970s as a doctor in Zululand

    in South Africa. The women who still lived in a traditional way, in mud huts, wanted to be fattened up for their menfolk, who saw in a fat wife a sign of

    their own success and prestige. These women would ask for medicine to become even fatter than they already were. By contrast, the young women who attended university wanted medicine to make them thinner than they already were. It almost seems as if, for human beings, there is no contentment with their body size.

    If overeating is not in itself a disease, it certainly has health consequences. By now, there surely cannot be anybody left who does not know that obesity causes Type II diabetes, any more than there are smokers who do not know that smoking is bad for them. When I started out as a doctor, Type II diabetes was often known as maturity-onset diabetes, but as children have grown

    fatter and fatter, maturity has nothing to do with it.

    The economic consequences of fat are enormous, if health economists are to be believed. Obesity-related medical costs were 9.1% of all annual medical costs in 2006, up from 6.5% in 1998, according to a study released last year from the Centers for Disease Control and Prevention and RTI

    International, a nonprofit research institute. The annual health-care costs of obesity in America have risen from $74 billion in 1998 to $147 billion in 2008.

    According to a paper presented at the Obesity Society's annual conference last year, fat people are less productive than thin. They take more time off work because of their various ailments, and when they are at work the

    morbidly obese produce less, equivalent to 22 days of lost production per year. The health-care costs and lost production caused by obesity are driving American manufacturers to locate to countries where the population, for the time being, still has a lean and hungry look.

    The fiscal consequences of obesity for America have also just increased, with the recent passage of the health-reform bill. Obesity is disproportionately

    concentrated among those previously uninsured, who will now presumably

    have access to more care, possibly including expensive bariatric surgery.

    Indeed, obesity is associated causatively to so many expensive diseases (rather as smoking is) that the health-care costs of treating the impoverished obese are likely to be enormous. Since treatment is unlikely

    by itself to make this sector of the population more employable or productive, America has just assumed an economic cost without an economic benefit. Truly, economics is the dismal science.

    Is there no hope, then? In one rather peculiar sense there is. The whole world is becoming fatter, not just America. Not long ago in Bangkok I observed some children, obviously of the elite, emerging from a school. There are not many fat people in Thailand, but these children were fat.

    Like so many of their counterparts in the West, they seemed unable, or

    unwilling, to progress further than a few yards without refreshing themselves with sweetened drinks and fast fatty food. And they were being collected by chauffeurs or adoring parents so that they might be spared the rather minimal exercise afforded by going home by public transportation. As yet in Thailand, the poor mostly cannot afford to be fat, but that time will come, and then the great reversal will occur: The elite will abandon its fattening habits, and take seriously the advice of the late Duchess of Windsor: that one can be neither too rich nor too thin.

    In the West, the march (or waddle) of obesity is in step with other social (or antisocial) developments. Obesity in Britain, for example, has increased pari

    passu with the splintering of families: and now it is never too early to teach children lack of self-control.

    The connection between the fragmentation of the family and obesity is easy

    to understand. Of course, there is no one-to-one correspondence between the two phenomenain human affairs there never is such a close fitbut

    there is nevertheless a strong and comprehensible correspondence. For much of the population, family meals are a ritual of the past: Thirty-six percent of British children never eat a meal at a table with another member of their family or household (we have now passed the milestone long desired by radical social reformers, more children being born illegitimate than

    legitimate). In the homes of the poor, the unemployed and the single parents that I used to visit as a doctor, I would find no evidence of cooking ever having been done there. Fatty take-away meals and ready-prepared foods heated in the microwave were the diet, together with almost constant snacks. There was not even a table to eat at: an absence that was not the

    consequence of raw poverty, since the flat-screen television would have been large enough, turned horizontal, to serve as a dining table.

    In these circumstances, children graze or forage; but unlike previous hunter

    gatherers, they do not come up against a scarcity of food, but rather a surfeit

    of it. Nothing is easier for them than to overindulge, and the appetite grows with the feeding. Their tastes never develop beyond the most instantly gratifying types of food, sugary and fatty, and they eat like children for the rest of their lives; they never learn the discipline of subordinating their appetite to the exigencies of family life and social convention. They are like Pooh Bear, for whom it is always time for a little something. It is hardly surprising if, like Pooh Bear's, their waistlines expand until they can't fit into a normal seat.

    Family and social meals are among the most powerful teachers of self-control in the human repertoire. They teach that the appetite of the moment is not, or rather ought not to be, the sole determinant of one's behavior. The pattern of grazing or foraging independently of everyone else teaches precisely the opposite lesson. It is hardly surprising that those who do not experience family or social meals early in life exhibit the lack of self-control that underlies so much modern social pathology in the midst of plenty.

    These social, or antisocial, developments have taken place precisely at a time when electronic means of entertainment have become available to all. For the uneducated, the world is an intolerably dull and slow-moving place by comparison with the excitement available at the press of a button or the flick of a switch. Why, then, move off your couch and risk the ennui of the real

    world? You can satisfy your appetite and occupy the vacuum of your mind at the same time, at most wriggling like a maggot in sawdust. The

    availability of constant entertainment is one of the causes of obesity. By taking on responsibility for the health consequences of obesity, the government has given itself the locus standi to interfere in many aspects of

    human existence. If obesity kills, is it not the government's duty to prevent it? He who pays the doctor decides the prophylaxis. Positive encouragement of

    healthy eating won't work, nor mere printed warnings that some foods are unhealthy (people who are prepared to eat doughnuts with pink and blue icing are unlikely to desist on learning that they contain nothing good for the

    bowels or any other organ).

As usual, therefore, prohibition beckons. Regulation of the sugar and fat

    content of ready-prepared and fast foods is likely to be proposed and perhaps eventually accepted, though not without a very fierce rear-guard action by the food industry. If John Doe will not eat his greens, Uncle Sam will make

    him, if necessary by restricting the availability of other foods. No one will raise moral psychology of the question of obesity, for fear of sounding

    uncompassionate and reactionary.

    In search for an amelioration, the temptation is to an intemperate

    authoritarianism, forgetting that the avoidance of obesity, pace the

    Duchess of Windsor, is not the whole purpose of life. But teaching children to cook and eat together might help overcome the crudity of their eating habits: the price of more refined, and in this instance nonfattening, pleasures always being effort.

    To reduce the attraction of fast food, prepared meals and soft drinks, and to save the planet from polystyrene dishes, a system of returnable deposits on

    packaging might be tried. This would slow down fast food a little, and tip the balance in favor of home preparation.

    No doubt the government will also promote sports as a remedy for and preventive of obesity. This, of course, would be an extremely irresponsible solution, for sports are already, even with the slothful population that we have, by far the most common cause of injury in Western societies. If the obese were suddenly to start exercising, emergency rooms would not be able to cope. For the sake of our health, let us have no sports.

Text B

    Can you be both obese and healthy?

    Countless epidemiological studies have shown that as you move from a

    normal body weight towards obesity the risk of many chronic diseases increases exponentially. However, more and more research suggests that the relationship

    between body weight and health is much more nuanced than previously thought.

    Recent estimates suggest that approximately one in three obese individuals

    remain metabolically healthy (displaying normal blood glucose, blood

    lipids, blood pressure, and a healthy cytokine profile) despite their excess

    weight. These same individuals may have a similar risk of developing heart disease and diabetes as their skinny counterparts and they may actually become less healthy by losing weight!

    Thus, as we shall see below, there is certainly more to health than the number on one’s bathroom scale.

    Historical background:

    It all started in 1965. Two researchers, Albrink and Meigs, were performing a general investigation into the health of factory workers, and noted a rather counterintuitive result: that many obese men had healthy levels of triglycerides in their blood.

    In 1982, Ethan Sims first included the designation of "healthy obese" subtype in

    his classification of obesity, thereby first identifying a unique subset of obese individuals that appear to be at least partially protected from the development of the metabolic disturbances generally attributed to obesity.

    Unfortunately, despite awareness of the metabolically health obese phenotype

    for close to 30 years, there currently exist no established criteria by which to define these individuals.

    What defines a metabolically healthy obese individual?

    The defining characteristics of the metabolically healthy obese phenotype, in contrast to obese individuals with metabolic risk, include limited abdominal, particularly visceral fat accumulation, an earlier onset of obesity (<20 years) and high levels of physical activity. Additionally, black obese individuals have a greater tendency of being metabolically healthy in contrast to white obese.
