OBESITY EPIDEMIC CHALLENGED BY EXPERTS


When reading an article such as the one from Pennlive.com we tend to think that perhaps there is hope that the anti-obesity campaign will not corrupt public opinion to the level the anti-tobacco fear mongering campaign did.

The article exposes exactly the same points we have been bringing up for the last three years on the obesity issue. There is a very important factor that the article doesn’t highlight however, but that must be emphasized at every opportunity because it has changed the ‘’technical’’ perception of obesity, overnight: ‘’ In 1998, the U.S. National Institutes of Health brought U.S. definitions into line with World Health Organization guidelines, lowering the normal/overweight cut-off from BMI 27.8 to BMI 25. This had the effect of redefining approximately 30 million Americans, previously "technically healthy" to "technically overweight". (source Wikipedia). As for Health Canada, they made their ‘’adjustment’’ in 2003. In Quebec alone, that ‘’adjustment’’ created an additional 1 million obese people from one day to the next.

Excerpts from the long but most interesting read: Some experts doubt obesity epidemic

LONDON (AP) — Go on, have another doughnut. According to some experts whose views are public health heresy, the jury is still out on how dangerous it is to be fat.
"The obesity epidemic has absolutely been exaggerated," said Dr. Vincent Marks, emeritus professor of clinical biochemistry at the University of Surrey.
…….

But obesity contrarians say that there's no data proving why being fat — in itself — would be dangerous. "There's no good causal connection," said Eric Oliver, author of Fat Politics and a political science professor at the University of Chicago.

Blaming obesity for diabetes and heart attacks, Oliver says, is like blaming lung cancer on bad breath rather than on smoking. Excess weight may actually be a red herring, Oliver says, since other factors like exercise, diet or genetic predispositions towards diseases are harder to measure than weight.

In addition to questioning the dangers of being fat, researchers like Marks also criticize oft-repeated alarmist projections about the rise in obesity — like the British government's warning that nearly half of Britain will be obese by 2050.

Those simply aren't based on good evidence, they say.
……..

In 2005, Katherine Flegal of the United States' Centers for Disease Control and Prevention published a study in the Journal of the American Medical Association, finding that overweight people typically live longer than normal-weight people. More than a dozen other studies have come to the same conclusion.

Outrage ensued. Prominent health experts called the research flawed and worried that people would gleefully supersize their meals.
………

Some obesity skeptics question the motives of experts who make dire predictions about obesity.
With millions of dollars for obesity researchers, an industry of anti-fat drugs, and a boom in the number of doctors offering surgeries like stomach-stapling, the more fat people there are, the more profits there will be in selling them solutions.

Experts on both sides of the obesity debate have often criticized WHO's overweight and obesity measures, saying they are too low.

When WHO defined the body mass index scores constituting normal, overweight and obese, they appeared to be the result of an independent expert committee convened by WHO.

Yet the 1997 Geneva consultation was held jointly with the International Obesity Task Force, an advocacy group whose self-described mission is "to inform the world about the urgency of the (obesity) problem."

According to the task force's most recent available annual report, more than 70 percent of their funding came from Abbott Laboratories and F. Hoffman La-Roche, companies which make top-selling anti-fat pills.

The task force remains one of Europe's most influential obesity advocacy groups and continues to work closely with WHO.

The blurred lines between pharmaceutical money and obesity groups have also caused concern in Britain. In 2006, one of the country's top obesity doctors quit the organization he founded to combat obesity, the National Obesity Forum, complaining that its goals had been skewed by drug money.

"There's not a lot of money in trying to debunk obesity, but a huge amount in making sure it stays a big problem," said Patrick Basham, a professor of health care policy at Johns Hopkins University.

Still, while skeptics insist that obesity warnings must be taken with a grain of salt, nearly all agree that while a little bit of extra padding may not be too deadly, too much almost certainly is.

"The vast majority of people who get labeled under the obesity epidemic are well under 300 pounds and probably are not facing big health consequences," Oliver said. "It's the morbidly obese people who should be worried."

MANDATORY MONITORING OF CHILDREN'S BODY MASS INDEX

On October 17, 2007 we commented on a Denver Public School District policy that weighed children and issued health report cards to their parents. We were appalled by this practice then, we are even more appalled now that it has become a state legislation in the state of Georgia.

Excess weight or even obesity does not automatically equate
to bad health or sickness. Many children are plump or fat in their childhood but lose this excess weight in adolescence or adulthood without any further complications or illnesses. The duty of all adults, whether school authorities, neighbors, relatives or friends, is to report to the child welfare authorities any sign of neglect or abuse suspected in a child. When there are no noticeable health problems or signs of neglect, routinely passing judgment on the child’s weight is totally unwarranted, especially when it cannot be predicted what damage this evaluation can cause to the child’s mental and psychological state of mind at the vulnerable age when self esteem and acceptance by their peers is of utmost importance.

Senate mandates weighing Georgia kids twice a year
New law would requires schools to track weight and BMI

Georgia's elementary school children will be weighed and measured twice a year by school officials under a bill that passed the Senate Friday.

The legislation requires schools to track kids' body mass index, a combination of height and weight used to determine whether the child is healthy. The bill, sponsored by Sen. Joseph Carter (R-Tifton) requires that schools post the aggregate BMI information on their Web sites and follow state regulations on offering physical education classes.

Carter said the bill would work much like test scores, with schools reporting their data so parents could check out how they measure up to other area schools. Children would be weighed in a confidential office setting and their personal data would not become public, he said.

"Sally, step into the office, step up on the scale, that's about as invasive as it gets," he said. More than one in three kids in Georgia is overweight, he said. "The presence of childhood obesity is staggering."

Arkansas was the first state to implement such a rule, in 2003. The bill, which mirrors legislation in several other states, passed 37 to 13 after a heated debate.

Sen. Preston Smith (R-Rome) said "the long arm of the government" should stop reaching into peoples' private lives.

He said worries that schools' will pressure children to lose weight and stigmatize them, mimicking what he worried school officials would say: "Come on, pick it up fat kid, we're not going to get money if you don't!""

As he left the podium, refusing to engage in a debate, Sen. Renee Unterman (R-Buford) who supports the bill, shouted "chicken!" at him.

It's not the first time lawmakers have tried to take up childhood obesity. Carter introduced a bill in 2006 that would have required more PE for Georgia elementary and middle schoolers, but the measure failed.

THE FAT PHOBIA

We have been trying to bring this phenomenon to the attention of the media and the health authorities, for some time. Naturally, because we don’t hold any fancy medical degrees, our worries were simply ignored.

Any campaign that goes overboard, no matter how noble the end, is bound to bring perverse side effects that can often be worse than the problem it tries to solve. Public health has to go back to the days when they were looking after infectious diseases. Lifestyle choices are not something that public health should meddle with. There are competent and qualified medical authorities that can deal with the problems on a one to one basis with patients and those who seek their advice, according to the individuals’ specific needs and ways to effectively help them.

There isn’t a ‘’one fit all’’ miracle solution. We and our children, are not automatons that can be programmed to act and react uniformly to public health’s theoretical solutions.

Obesity worries show signs of backfiring

Weight becoming an unhealthy obsession for some kids, parents

Sharon Kirkey, Canwest News Service
Fears about obesity are feeding "fat phobia," experts warn.

They're worried more healthy kids are obsessing about weight -- and more parents are projecting irrational fears about fat on their children.

Some question whether the obesity "epidemic" is even real, and whether schools have any business trying to fight obesity.

"It seems like whenever we decide there is an epidemic people run around helter skelter trying to solve the problem without really thinking about it in an organized fashion," says Dr. Leora Pinhas, a child psychiatrist and psychiatric director of the eating disorders program at Toronto's Hospital for Sick Children.

"I'm not convinced that telling kids that they're fat, or that they might get fat, is a way of solving the problem."

The hospital has seen preteens and teens who attended obesity-prevention programs at school.
They then "decide they're going to be the best kid at not getting fat, (and) then end up losing so much weight that they put themselves medically at risk," Pinhas says.

"They're little kids. They don't have to lose a lot of weight to get sick.

"We have had kids who have been weighed in the gym and then had to deal with how they felt about their weight, and these may have been kids who never weighed themselves before and it hadn't been a concern before," Pinhas says.

Children are being taught in nutrition classes how to cut all fat from their diet.

But, "who buys food, who makes the meals? It's not the eight-year-old," Pinhas says.
"All we seem to do is keep placing more unreasonable expectations on children that can be confusing for them."

Children are hearing that fat is bad. Period. And where anorexia and bulimia before adolescence was once unheard of, hospitals are now seeing eating disorders in children as young as seven.
Children are social sponges, Pinhas says.

" How many times does a kid have to overhear a conversation like, 'Wow, you look great, you lost weight,' or 'Look at my butt, it's really fat, I should cut down on what I'm eating,' or 'All that fat is going to give you a heart attack?'"

Susan Willard says a lot of the pressure to be thin now comes from home.

"It's not infrequent that we see patients who have families who are over-invested in body shape and weight," says Willard, clinical director of the eating disorders treatment centre at River Oaks Hospital in New Orleans, where many patients come from Canada.

In these families, calorie counting, fat-gram counting and exercise "become a primary focus in the home and at the table.

"Kids who grow up in families of that sort believe that it is of very primary importance that they 'eat right' and stay fit and healthy, and that ultimately can turn out to be extremely unhealthy," says Willard, a professor of psychiatry and pediatrics at Tulane University School of Medicine and co-author of the book, When Dieting Becomes Dangerous.

But parents also live in a culture that says what matters most is to be thin. "They're being told over and over again that if their kid is fat, it's like a death sentence. They're being told they're not good parents," Pinhas says.

"I think we should stop worrying about whether someone is fat or not because it's not necessarily an indicator of poor lifestyle or imminent mortality or morbidity."

Dr. Ahmed Boachie says many teens whose weight is healthy believe wrongly that they're overweight. Even campaigns to rid schools of snacks can lead to negative messages and neurosis about food.

"And when they feel that way they're more likely to be dieting," says Boachie, clinical director of the eating disorders program at Southlake Regional Health Centre in Newmarket, Ont.
But a study of nearly 15,000 girls and boys aged nine to 14 showed that dieting not only doesn't work, it actually leads to weight gain. Kids severely restrict their diet, then lose control and binge or overeat, and the cycle continues.

What's more, dieting is considered a risk factor for eating disorders such as anorexia nervosa or bulimia nervosa -- "very chronic and difficult illnesses with often fatal outcomes," Boachie says. Most people who develop eating disorders were never overweight or obese to begin with, he says.

"Eating disorders are illnesses. If any parent has any weight concerns, instead of listening to the street definition of obesity, contact the experts," Boachie says.
A recent study found that girls who eat at least five meals a week with their family are less likely to be preoccupied with dieting.

Signs that a child or teen might be engaged in extreme dieting or have an eating disorder include coming home from school and saying they have already eaten, separating themselves from family at meal times, and complaining of being cold and tired all the time.

Younger children often don't stop eating completely, but they eat less, complain their stomach hurts or say they're not hungry.

"Don't forget, they're small to start with. Losing a few kilos is enough to lose a significant proportion of their body weight," Pinhas says.

"What we end up seeing, sometimes, are kids who just stop growing."

Treating people like luggage for the sake of Highlighting the Obesity Crisis

From Australia, the trend setters for ‘’nannyism’’, comes this story about how the obese should be billed a ‘’heavy load’’ surcharge when buying their plane ticket.

In a society where everything has to make money sense, it’s not surprising, but appalling nonetheless, that a leading nutritionist would suggest that people be treated the same way as luggage. As some commentators to this story suggested, it should be pointed out to Tickell, that according to the latest international standards for ‘’normality’’ in weight, thin people are the minority. Aren’t we constantly told that majority rules and the minority should just shush up and put up? Tickell had better start piling on these calories if he wants a say in the issue!

Sorry but just couldn’t resist the sarcasm this morning.

Australia airline 'fat tax' urged

A leading Australian nutritionist has urged airlines to charge obese passengers more for their seats.

Dr John Tickell believes a "fat tax" would highlight his country's obesity crisis and make commercial sense, as heavier loads increase fuel costs.

But health groups have warned that to single out people with weight problems could cause them emotional stress.

Recent studies estimate that 67% of Australian men and over half of women aged over 25 are overweight or obese.

Experts have warned that by 2030 half of the country's children will be overweight or obese if the problem goes unchecked.

In March, Australian health officials were forced to equip their fleet of ambulances with heavy-duty stretchers to cope with the sharp rise in overweight patients.

Too precious

Dr Tickell, a leading nutritionist and author, told the BBC that society should take a more hardline stance against obesity and get tough on fat airline passengers.

He said that Australian airlines should impose charges on their overweight clients, as they do for excess baggage, because heavier loads increase fuel costs.

"I fly Sydney to Perth - five hours - and being totally disadvantaged by some huge person next to me literally flopping over into my seat. Why should I pay the same as them?" he asked.

Dr Tickell said it was important to start highlighting Australia's obesity crisis.

"I think we're a bit too nice, we're a bit too precious about minority groups. I think the majority group must have something to say too," he added.

But the chief executive of the Australasian Society for the Study of Obesity, Dr Tim Gill, said penalty charges should not be imposed on overweight passengers.

"It's not fair to single out those people who have a problem, which is already impacting greatly on their life, and make them feel like pariahs," he said.

A spokesman for the Australian budget airline, Jetstar, said it had no plans to charge larger passengers more for their seats.

Airlines are, however, monitoring long-term trends in the size and shape of their customers, the BBC's Phil Mercer in Sydney says.

IT IS TIME EPIDEMIOLOGY TAKES A FEW STEPS BACK

The ink of the latest report from the World Cancer Research Fund and American Institute for Cancer Research urging us that in order to stay healthy we should maintain a body mass index as close to 18 as possible isn’t even dry yet, that a new study is now telling us that actually cancers are not associated with being somewhat overweight and higher weights are associated with better survivals when we get sick. How can we possibly trust any of the advice these so called scientists give us about our personal health? How can governments continue to rely on epidemiological studies to legislate? Isn’t it time epidemiology takes a few steps back and performs what it was meant to perform – studies of infectious diseases?

Clean your plate: a few extra pounds won't kill you

Weight helps to beat some illnesses, study finds
SHARON KIRKEY, CanWest News Service
Deaths studied were grouped into three major categories: cardiovascular disease, cancer and all other causes.
For each cause, the team estimated excess deaths in each category of body mass index, or BMI. A BMI of 25 to less than 30 is considered overweight; a BMI of 30 and over is obese.
Someone who is 5 feet, 10 inches tall and weighs 174 to 208 pounds would be considered overweight, according to their BMI. More than that, and they're obese.
Obesity - but not overweight - was strongly associated with an increased risk of dying from coronary heart disease, stroke or other forms of cardiovascular disease, accounting for 112,159 excess deaths in the United States in 2004.
The team estimates that obesity is associated "with somewhere between nine and 13 per cent of all cardiovascular mortality," said lead author Katherine Flegal, senior research scientist at the Centres for Disease Control in Hyattsville, Md.
Overall, the team found no association between obesity and cancer deaths when all cancers, including lung cancer, were grouped together.
"We're not trying to say overweight is protective," Flegal said, but there is some evidence higher weights are associated with better survival when you get sick.
