Are you one of the zillions who made a New Year’s Resolution to lose weight? Well Paul Campos, “a professor of law at the University of Colorado, Boulder” has written a book entitled The Obesity Myth: Why America’s Obsession With Weight Is Hazardous to Your Health
“ACCORDING to the United States government, nearly 7 out of 10 American adults weigh too much. (In 2010, the Centers for Disease Control and Prevention categorized 74 percent of men and 65 percent of women as either overweight or obese.)
But a new meta-analysis of the relationship between weight and mortality risk, involving nearly three million subjects from more than a dozen countries, illustrates just how exaggerated and unscientific that claim is.”
“The meta-analysis, published this week in The Journal of the American Medical Association, reviewed data from nearly a hundred large epidemiological studies to determine the correlation between body mass and mortality risk. The results ought to stun anyone who assumes the definition of “normal” or “healthy” weight used by our public health authorities is actually supported by the medical literature.
The study, by Katherine M. Flegal and her associates at the C.D.C. and the National Institutes of Health, found that all adults categorized as overweight and most of those categorized as obese have a lower mortality risk than so-called normal-weight individuals. If the government were to redefine normal weight as one that doesn’t increase the risk of death, then about 130 million of the 165 million American adults currently categorized as overweight and obese would be re-categorized as normal weight instead.”
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems. People are considered obese when their body mass index (BMI), a measurement obtained by dividing a person’s weight in kilograms by the square of the person’s height in metres, exceeds 30 kg/m2
Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications or psychiatric illness. Evidence to support the view that some obese people eat little yet gain weight due to a slow metabolism is limited; on average obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass.
Dieting and physical exercise are the mainstays of treatment for obesity. Diet quality can be improved by reducing the consumption of energy-dense foods such as those high in fat and sugars, and by increasing the intake of dietary fiber. Anti-obesity drugs may be taken to reduce appetite or inhibit fat absorption together with a suitable diet. If diet, exercise and medication are not effective, a gastric balloon may assist with weight loss, or surgery may be performed to reduce stomach volume and/or bowel length, leading to earlier satiation and reduced ability to absorb nutrients from food.
Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children, and authorities view it as one of the most serious public health problems of the 21st century Obesity is stigmatized in much of the modern world (particularly in the Western world), though it was widely perceived as a symbol of wealth and fertility at other times in history, and still is in some parts of the world.
Cha Cha Cha.
“To put some flesh on these statistical bones, the study found a 6 percent decrease in mortality risk among people classified as overweight and a 5 percent decrease in people classified as Grade 1 obese, the lowest level (most of the obese fall in this category). This means that average-height women — 5 feet 4 inches — who weigh between 108 and 145 pounds have a higher mortality risk than average-height women who weigh between 146 and 203 pounds. For average-height men — 5 feet 10 inches — those who weigh between 129 and 174 pounds have a higher mortality risk than those who weigh between 175 and 243 pounds.”
“Now, if we were to employ the logic of our public health authorities, who treat any correlation between weight and increased mortality risk as a good reason to encourage people to try to modify their weight, we ought to be telling the 75 million American adults currently occupying the government’s “healthy weight” category to put on some pounds, so they can move into the lower risk, higher-weight categories.”
“In reality, of course, it would be nonsensical to tell so-called normal-weight people to try to become heavier to lower their mortality risk. Such advice would ignore the fact that tiny variations in relative risk in observational studies provide no scientific basis for concluding either that those variations are causally related to the variable in question or that this risk would change if the variable were altered.”
“This is because observational studies merely record statistical correlations: we don’t know to what extent, if any, the slight decrease in mortality risk observed among people defined as overweight or moderately obese is caused by higher weight or by other factors. Similarly, we don’t know whether the small increase in mortality risk observed among very obese people is caused by their weight or by any number of other factors, including lower socioeconomic status, dieting and the weight cycling that accompanies it, social discrimination and stigma, or stress.”
“In other words, there is no reason to believe that the trivial variations in mortality risk observed across an enormous weight range actually have anything to do with weight or that intentional weight gain or loss would affect that risk in a predictable way.”
“How did we get into this absurd situation? That is a long and complex story. Over the past century, Americans have become increasingly obsessed with the supposed desirability of thinness, as thinness has become both a marker for upper-class status and a reflection of beauty ideals that bring a kind of privilege.”
“In addition, baselessly categorizing at least 130 million Americans — and hundreds of millions in the rest of the world — as people in need of “treatment” for their “condition” serves the economic interests of, among others, the multibillion-dollar weight-loss industry and large pharmaceutical companies, which have invested a great deal of money in winning the good will of those who will determine the regulatory fate of the next generation of diet drugs.
Anyone familiar with history will not be surprised to learn that “facts” have been enlisted before to confirm the legitimacy of a cultural obsession and to advance the economic interests of those who profit from that obsession.
Don’t expect those who have made their careers on fomenting panic to understand that our current definition of “normal weight” makes absolutely no sense.”
IOW, what we’ve got here is a revamped rendition of “The MYth of Heerosexual AIDS” (Yes I noticed what was on the blackboard behind Campos in the photo too.)
