Do BMI letters help?

A us state experimented with sending parents letters about their child’s body mass index in an effort to fight obesity.

SIXTH-GRADE (equivalent to Year Six) boys were lining up to be measured in the Mann Arts and Science Magnet Middle School library in Arkansas, United States.

As they took off their shoes and emptied their pockets, they joked about being the tallest. “It’s an advantage,” said one. “You can play basketball,” said another.

A taller dude can get more girls!” a third student offered. Everyone laughed.

What they didn’t joke about was their weight.

Anndrea Veasley, the school’s registered nurse, had them stand one by one.

One boy, Christopher, slumped as she measured his height. “Chin up slightly,” she said. Then Veasley asked him to stand backward on a scale so he didn’t see the numbers.

She silently noted his height as just shy of four feet, seven inches (139.7 centimetres) and his weight as 115.6 pounds (52.4 kilogrammes).

His parents would later be among thousands to receive a letter beginning, “Many children in Arkansas have health problems caused by their weight.”

The letter includes each student’s measurements, as well as their calculated body mass index (BMI), an indicator of body fat.

The BMI number categorises each child as “underweight”, “normal”, “overweight” or “obese”.

Christopher’s BMI of 25.1 put him in the range of obesity.

> Is it really useful?

In 2003, Arkansas became the first US state to send home BMI reports about all students as part of a broader anti-obesity initiative.

> But in the 20 years since, the state’s childhood obesity rates have risen to nearly 24% from 21%, reflecting a similar, albeit higher, trajectory than national US rates.

During the Covid-19 pandemic, the state obesity rate hit a high of more than 26%.

Still, at least 23 US states followed Arkansas’ lead and required height and weight assessments of students.

Some have since scaled back their efforts after parents raised concerns.

One school district in Wyoming used to include a child’s BMI score in report cards, a practice it has since stopped.

Ohio allows districts to opt in, and last year, just two of 611 school districts reported BMI information to the state.

And Massachusetts stopped sending letters home.

Even Arkansas changed its rules to allow parents to opt out.

Multiple studies have shown that these reports, or “fat letters” as they’re sometimes mockingly called, have had no effect on weight loss.

And some nutritionists, psychologists and parents have criticised the letters, saying they can lead to weight stigma and eating disorders.

BMI as a tool has come under scrutiny too, because it does not consider differences across racial and ethnic groups, sex, gender, and age.

In 2023, the American Medical Association called the BMI “imperfect” and suggested it be used alongside other tools such as visceral fat measurements, body composition and genetic factors.

Meant for awareness

All that highlights a question: What purpose do BMI school measurements and letters serve?

Nearly 20% of American children were classified as obese just before the Covid-19 pandemic – up from only 5% some 50 years ago – and lockdowns made the problem worse.

It’s unclear what sorts of interventions might reverse the trend.

Dr Joe Thompson, a paediatrician who helped create Arkansas’ programme and now leads the Arkansas Center for Health Improvement, said BMI letters are meant to be a screening tool, not a diagnostic test, to make parents aware if their child is at risk of developing serious health issues such as heart disease, diabetes and respiratory problems.

> Sharing this information with them is critical, he said, given that many don’t see it as a problem because obesity is so prevalent.

Arkansas is also a rural state, so many families don’t have easy access to paediatricians, he said.

Dr Thompson said he’s heard from many parents who have acted on the letters.

“To this day, they are still our strongest advocates,” he said.

The programme also led to new efforts to reduce obesity.

Some school districts in Arkansas have instituted “movement breaks”, while others have added vegetable gardens, cooking classes and walking trails.

One district sought funding for bicycles.

The state does not study whether these efforts are working.

Researchers say the BMI data also serves an important purpose in illuminating population-level trends, even if it isn’t helpful to individuals.

Parents are generally supportive of weighing children in school, and the letters have helped increase their awareness of obesity, research shows.

At the same time, few parents followed up with a healthcare provider or made changes to their child’s diet or physical activity after getting a BMI letter, several other studies have found.

In what is considered the gold standard study of BMI letters, published in 2020, researchers in California found that the letters home had no effect on students’ weight.

Dr Hannah Thompson, a University of California-berkeley assistant professor who coauthored the study, said most parents didn’t even remember getting the letters.

“It’s such a tiny-touch behavioural intervention,” she said.

Practical advice needed

Arkansas now measures all public school students in even grades annually, except for 12th graders (equivalent to Form Six or pre-university) because by that stage, Dr Thompson said the students are “beyond the opportunities for schools to have an impact”.

The change also came after many boys in one school wore leg weights under their jeans as a prank, he said. 

Kimberly Collins, 50, remembers being confused by the BMI letters sent to her from the Little Rock School District in Arkansas, stating that all her children were considered overweight and that one daughter was classified as obese.

“It offended me as a mama,” she said. “It made me feel like I wasn’t doing my job.”

She didn’t think her children looked overweight and the family paediatrician had never brought it up as a concern.

 Assist Prof Thompson said that’s the biggest problem with BMI letters: Parents don’t know what to do with the information.

Without support to help change behaviour, she said, the letters don’t do much. >

“You find out your child is asthmatic, and you can get an inhaler, right?” she said.

“You find out that your child is overweight and where do you even go from there? What do you do?”

Dr Kevin Gee, a professor at the University of Californiadavis, who has studied BMI letters, said the mailings miss cultural nuances.

In some communities, for example, people prefer their children to be heavier, associating it with comfort and happiness.

Or some eat foods that they know aren’t very nutritious, but are an important way of expressing love and traditions.

“There’s a lot of rich contextual pieces that we know influences rates of obesity,” he said.

“And so, how do we balance that information?” &

Collins’ daughter, now 15, said that as she’s grown older, she increasingly feels uncomfortable about her weight.

People stare at her and sometimes make comments. (Collins’ mother asked that her daughter’s name not be published because of her age and the sensitive nature of the subject.)

“On my birthday, I went to get my allergy shots and one of the nurses told me, ‘You are getting chubbier’,” she said.

“That didn’t make me feel the best.”

Collins said it pains her to see her soft-spoken daughter cover herself with her arms as if she’s trying to hide.

The teenager has also begun sneaking food and avoids the mirror by refusing to turn on the bathroom light, Collins said.

The girl signed up for tennis, but stopped after other children made fun of her, her mother said. (See From teen to adult: Weight stigma lingers on p8)

Looking back, Collins said, while she wishes she had paid more attention to the BMI letters, she also would have liked practical suggestions on what to do.

She said she had already been following the shortlist of recommended healthy practices, including feeding her children fruits and vegetables, and limiting screen time.

She isn’t sure what else she could have done.

Now everyone has an opinion on her daughter’s weight, Collins said.

One person told her to put a lock on the fridge.

Another t old her to buy vegan snacks.

Her mother bought them a scale.

“It’s a total uphill climb,” Collins said with a sigh. – KFF Health News/tribune News Service

Not the best for weight

 Although BMI is widely used as a measure of weight, it is not very accurate and can lead to the mistreatment of obesity and eating disorders.

Obesity is more complex than just overeating , Not just fat

 In conjunction with World Obesity Day yesterday, we take a look at how the understanding of this condition of excess weight has evolved.

We need to avoid weight bias where we make the assumption that people are obese solely because of their own choices. — Photos: 123rf.com

For as long as she could remember, Jane had always been plus-sized.

As a child, her family doted upon her as she was never picky about food and would eat anything given to her.

In school, she was always physically bigger compared to the rest of her peers.

She was often teased by her friends for her body size, but she was constantly reassured by her family that she was just “big-boned”, just like the rest of her siblings and family members.

However, by the time she reached young adulthood, she started feeling more self-conscious about her body size and embarked upon multiple cycles of crash dieting and exercise regimes.

She successfully lost weight a few times; however, each time she lost weight, she would eventually lapse into bouts of uncontrollable binge-eating.

As a result, she constantly struggled to keep the weight off and would always gain back the weight she lost, if not more.

With time, she became resigned to the fact that she was probably fated to be fat for life.

This led to body image issues, self-blaming, and even clinical depression that negatively affected her life and relationships.

The scale of the problem

Jane is not exactly a real person, but her story is very real – a coalescence of the lives of many people struggling with weight issues everywhere.

The global obesity epidemic, aptly coined “globesity”, is arguably one of the most important public health concerns of the late 20th and early 21st century.

As of 2016, the World Health Organization (WHO) estimated that 650 million adults worldwide were obese.

According to the World Obesity Atlas, these numbers are expected to increase, with the global obese population projected to breach the one billion mark by 2030.

It is also no longer news to us that Malaysia is effectively the fattest country in the region.

The 2019 National Health and Morbidity Survey (NHMS) reported that one in two Malaysian adults were either overweight (30.4%) or obese (19.7%), and one in three Malaysian children were overweight (15.0%) and obese (14.8%).

On top of this, if we account for the rampant weight gain seen during the Covid-19 movement control order, the current true numbers of obese people in Malaysia is likely even higher.

Traditionally, being overweight and obese has been viewed as a risk factor that increases an individual’s chances of developing metabolic diseases such as type 2 diabetes, hypertension (high blood pressure), cardiovascular (heart) disease, obstructive sleep apnoea, and musculoskeletal disorders such as osteoarthritis, among others.

This fact still very much holds true today.

However, in 2014, the American Medical Association declared obesity as a disease state in itself.

This actually had very far-reaching implications.

It effectively changed the way we view obesity – as more than just excessive fat deposition contributing to other diseases.

Obesity itself is now seen as a disease state that requires formal medical attention, proper treatment plans and prevention efforts.

The complexity of obesity

Experts worldwide have been calling for measures to be taken to curb this growing issue for decades, but the rates of obesity have continued to rise regardless.

The idea that obesity is a disease of the brain is gaining traction among scientists as the hypothalamus (in yellow) plays a key role in regulating our appetite and metabolism..The idea that obesity is a disease of the brain is gaining traction among scientists as the hypothalamus (in yellow) plays a key role in regulating our appetite and metabolism.>>

This is because obesity is a very complex issue with a lot of interconnected causes.

In the past, it was assumed that as our society became richer, we had to physically work less to get our food and this led to over-nourishment.

However, we now know that it is overly simplistic to think that obesity develops as a result of an individual just “eating too much”.

Instead, there are often multiple factors beyond our control that contribute to an individual developing obesity.

For example, people who come from disadvantaged socioeconomic backgrounds may not have the financial privilege of accessing healthy food options.

They may also not be educated enough to choose better quality food with their available resources.

Children born into these families with a history of obesity have higher chances of developing obesity later on in life.

This is partly contributed by genetic factors, as well as enduring lifestyle habits inculcated from a young age that may be difficult to change.

Obesity is also closely linked to the development of mood disorders such as depression and anxiety.

People suffering from depression also have a higher chance of developing eating disorders that subsequently lead to obesity.

A lot of these factors form vicious cycles that span generations.

On a population scale, we are living in an increasingly “obesogenic environment”.

This refers to the multiple physical, economic and sociocultural factors that collectively contribute to the development of an obese population.

For example, our built environment promotes a sedentary lifestyle.

Our roads are hardly pedestrian or bicycle-friendly.

Our public transportation system is not optimised, as the lack of last-mile connectivity remains a major hindrance for many.

As a result, most Malaysians are heavily dependent on motorised vehicles to get around, rather than walking or cycling.

Globalisation and industrialisation of the food supply chain have made ultra-processed foods more common now than ever.

Ultra-processed foods refer to those that have gone through a series of industrial processes, often with ingredients like high-fructose corn syrup, modified oils, food colouring and other additives to make the final product hyper-palatable.

These foods are commonly high in calories and easily over-consumed.

They are generally mass-produced and marketed by large companies, and are often much cheaper and more readily available compared to whole, nutritious food options.

As we start to understand more about obesity, it has become increasingly clear that it is, in essence, a disease of the brain.

The hypothalamus located in the brain plays a key role in regulating our appetite and metabolism.

The satiety centre in the hypothalamus is largely responsible for controlling our sensation of hunger.

When an individual develops obesity, the accumulation of excessive fat tissue actually leads to a host of hormonal changes within the body.

These hormonal changes not only suppress the satiety centre and increase hunger, but also slow down our metabolism rate.

Essentially, our body has a weight “setpoint”, and will try to revert to this setpoint despite our best efforts.

These underlying biological mechanisms are largely out of our voluntary control.

They also explain why people with obesity who embark on lifestyle changes to lose weight tend to hit a plateau after an initial weight loss.

In fact, after some time, they may regain some of the weight they lost initially.

Weight bias

The easy availability and affordability of ultra-processed foods is part of the obesogenic environment that makes it easy to gain excess weight. — TNS 
The easy availability and affordability of ultra-processed foods is part of the obesogenic environment that makes it easy to gain excess weight. — TNS

It is precisely because of these underlying complexities that we should be careful not to indulge in weight bias.

Weight bias, or weight stigma, refers to negative attitudes, beliefs and judgments toward individuals who are overweight and obese.

In other words, we have to avoid the over-simplistic assumption that people with obesity are the way they are as a result of their “poor life choices”.

This stigma is very common because body weight is a physical characteristic that is visible and is often the first thing we notice about a person.

Studies have shown that even doctors are guilty of weight bias.

These can range from explicit behaviours, such as outright fat-shaming and teasing, to implicit beliefs, such as seeing someone who carries excessive weight and immediately considering them to be lazy, undisciplined or unmotivated.

Shaming individuals with weight-related issues does not motivate positive behavioural changes.

Instead, it often leads to the development of unhealthy behaviours such as compulsive exercise, as well as eating disorders such as cycling between extreme fasting or dieting, and episodes of binge eating.

Worse still, when this becomes internalised, an individual believes that they deserve the stigma and discriminatory treatment because of their weight.

Internalised weight bias is strongly associated with unhealthy eating patterns, poor body image, low self-esteem and depression.

Striking a balance

Conversely, this by no means indicates that we should normalise obesity or dismiss the deleterious health effects associated with it.

Instead, an individual’s body fat excess needs to be objectively taken into context as one part of their overall health.

The body positivity movement promotes acceptance of all body types, shapes and sizes, and not assigning self-worth solely to outward appearances.

This need not be mutually exclusive with taking obesity seriously as a public health emergency requiring urgent attention.

Over the last few decades, there have been major advances in the medical treatment of obesity.

Bariatric surgery has long been proven to be very effective, but it comes with its own set of complications.

New medications have been developed to specifically target the hormonal changes in obesity and induce very effective weight loss.

However, these medications are still very expensive and may not be widely available.

It also does not take away the fact that prevention is still better than cure.

Once established, obesity is very difficult and arduous to treat due to the reasons explained above.

Preventing obesity requires a concerted effort.

Government policies need to be drafted holistically, keeping in mind that economic and structural development often have indirect population-wide health consequences in the long run.

The food industry needs to be regulated for responsible manufacturing and marketing practices.

Society as a whole also has a collective responsibility to recognize that obesity is a disease and consciously adopt a healthy culture to address and prevent it.

The theme for World Obesity Day 2023 is “Changing Perspectives: Let’s Talk about Obesity”.

It is apt that we keep the conversation going, correct misconceptions, end stigma, and collectively shift towards a rational and sustainable strategy to tackle this perennial issue.

Supersized and overweight civil servants

The public waiting their turn for services at a government department. - Filepic

When those two words describe a nation's public sector, it means it's truly a burden on taxpayers.

POOR civil servants! If you watched Disney’s animated film Zootopia, you would have caught the hilarious scene where the heroes, a rabbit and a fox, rushed to the Department of Motor Vehicles to check out a licence plate, only to get very, very slow service from the sloths manning the counter.

It would appear this stereotyping of civil servants’ work ethic is universal, which is why the parody tickled audiences everywhere.

Now Malaysians have another reason to make fun of their civil servants: they’re too fat. At least the ones in Putrajaya are, according to the 2015 National Health and Morbidity Survey (NHMS) which showed it has the highest rate of overweight and obese citizens.

It’s an established fact that Putrajaya is populated overwhelmingly by government employees, which means those living and serving in the very heart of the nation’s administrative capital are rather unhealthy.

That’s a bummer because, design-wise, Putrajaya got it right. It was a winner in the 75,001­ to 150,000-population category for the Whole City Award under the International Awards for Liveable Communities 2012.

In the paper submitted for the awards, Putrajaya boasted of having “lush greeneries surrounding buildings, infrastructure, (12) parks and gardens.” What’s more, the same paper took into account the need to keep Putra­jaya folks fit and healthy.

It noted that 28% of the residents had a normal BMI (Body Mass Index), 36.3% were overweight, 27.4% obese and 8.3% were even underweight. That was in 2011.

Just four years later, 37% of Putrajayans are said to be overweight and their obesity rate is 43%, according to the NHMS findings.

These are alarming jumps and more so when there were efforts like the Healthy Parks, Healthy People programme to get the residents to exercise to stave off lifestyle diseases like hypertension and diabetes. Among the activities was the Putrajaya Inter-Park Ride monthly cycling event.

So what gives? Why are Putrajayans and Malaysians on the whole so fat? We hold the title of Fatties of South-East Asia; some reports say the whole of Asia.

Some people may, in a perverse way, hail having an overly well-fed population as a sign of a nation’s prosperity. After all, the fattest people in the world are the Americans.

A How’s Life? 2015 Report by the Organisation for Economic Coopera­tion and Development ranked the United States as the nation with the most obese population. It also had the fattest children and the unhealthiest teenagers by a wide margin.

The findings are said to be a blow to the Obama administration and First Lady Michelle Obama because they have been championing this cause for years, including reducing sugar and salt from school lunches.

So if both the US and Malaysian Governments couldn’t stem the fat tide in their respective countries, who can? I would say it’s still the government and we the people.

What we have is a terribly bloated public sector. The Star, quoting Prime Minister’s Office statistics, pointed out that at 1.4 million employees, it’s the largest civil service in South-East Asia.

Supersized and overweight. That’s a double whammy and the kind of Malaysian Book of Records we don’t need. So for a start, how about really downsizing the civil service? After all, why do we need so many civil servants to serve a population that’s way smaller than those in neighbouring countries like Indonesia, the Philippines and Thailand?

Next, I support calls to make it mandatory for civil servants to lose the fat and stay healthy. This is especially so for those who have yet to develop serious illnesses like diabetes. If need be, withhold promotions and salary increases if they don’t meet this KPI.

The reason why I am pushing for this is because civil servants get free medical services in government hospitals and clinics, even after retirement.

That’s a longstanding benefit which I don’t object to, since my retired police officer father is a beneficiary. But with a large, unhealthy government workforce, you can imagine the humongous medical bill we taxpayers are burdened with.

If nothing is done, it will become a bigger burden because, as doctors have warned, 20 years from now, those overweight and obese citizens will be suffering from all sorts of illnesses from stroke, heart disease and kidney failure to diabetes.

All that “will increase the health budget to an unsustainable level,” Malaysian Medical Association president Dr Ashok Zachariah Philip told The Star.

Thanks to my role as the primary caregiver to my elderly parents who suffer from various illnesses, I know how scarily expensive medical care can be for those without access to free treatments.

As a private sector employee, I am grateful to be working for a company that gives me good medical coverage. But I have also bought my own health insurance to prepare for the day when I retire and lose my safety net. In the meantime, I work at staying healthy and medication-free.

As I said, I do not begrudge the medical benefit for government servants. What I do begrudge are those who take it for granted, instead of taking responsibility for their own well-being.

If the Government can work on getting its workforce in shape, non-public sector citizens too can do their part by eating less and more healthily and getting off our butts.

Admittedly, it’s hard now to go out for a run or even a stroll because of the current heat wave and haze. But we can try taking the stairs instead of the lift, drink more water than teh tarik and yes, eat less of our beloved nasi lemak.

Proud as we are that Time magazine ranked it as the ninth healthiest breakfast in the world, we know better. A dish that tastes that good cannot be healthy!

I leave this thought with you: The OEDC report, which measures the personal and economic health of nations, found that the United States indeed topped the chart in personal wealth and even the number of rooms in American homes.

So yes, they have the wealth but where’s the health?

Putrajaya the obese-city! Address obesity urgently

Two men cycling in front of the Palace of justice in Putrajaya

Malaysia has the highest percentage of overweight people in South-East Asia and the bulk of them are in Putrajaya. A survey has found that two out of five Malaysian civil servants are obese. The news is not good for the country’s health.

KUALA LUMPUR: It has been long known that Malaysia is the fattest country in South-East Asia. Now, it has been proven that the administrative capital of Putrajaya has the highest rate of overweight and obese people in the country.

Findings from the 2015 National Health and Morbidity Survey (NHMS) placed Putrajaya as the city with the highest percentage of overweight, obese and abdominally obese people in the country.

The study also suggests that the administrative capital’s population has a 37% chance of being overweight, while the obesity rate stood at 43%.

Even more startling, the NHMS said government and semi-government employees took the cake as those struggling most with obesity, with a 40.3% rate.

This could mean two out of every five of Malaysia’s civil servants may be obese.

Malaysia’s civil service has 1.4 million employees, according to the Prime Minister’s Office, and is the largest civil service in South-East Asia.

Other obesity demographics pointed out in the survey were Indians (43.5%), married adults (33.8%) and those who only studied up to secondary school (32.1%).


The findings put the Government in a rather red-faced situation, as it works on reversing the climbing number of obese and overweight Malaysians.

“As the number of people with obesity increases, the nation now is facing an upward surge of non-communicable diseases such as diabetes and cardiovascular diseases,” the survey concluded, describing the Malaysian obesity epidemic as alarming.

Although a review of public health policy was not necessary now, it opined, the Government was asked to provide more supportive environments for Malaysians to lead healthier lifestyles.

Malaysian Medical Association (MMA) president Dr Ashok Zachariah Phillip agreed, saying that the life of a typical government servant did not afford them much time or money to stay healthy.

“If you look at the strata, it’s usually the lower grade workers who are overweight because it takes money to keep fit. Government workers go to work at 7am, come back at 7pm and have no time between work and family to even think of exercising,” he said.

It doesn’t help either that basic essentials like white rice, sugar and oil are staple Malaysian diets and are unhealthy, he said.

“For us doctors, this could be a real headache 20 years down the road. We are going to have a growing population with stroke and heart disease, and kidney failures that will increase the health budget at an unsustainable level,” he added.

The Government needs to look into setting up more gyms in agencies and dish out incentives for employees to fight the bulge.

Health Minister Datuk Seri Dr S. Subramaniam said the figures were worrying.

“I don’t think the people are in the best state of health,” he said.

He said general sedentary work has a correlation to obesity, a trend which government agencies, namely the police, were trying to counter.

“The police recognised this recently and have taken some effort to make sure they have lean policemen. They will try to take action to meet this target,” Dr Subramaniam said yesterday.

Malacca and Perlis are the states with second and third highest obesity rates. Sabah and the Federal Territory of Labuan were the slimmest states.

Address obesity urgently




AMID the current heat wave, not only are we blue over the greens (The Star, April 4) with highland vegetables wilting and Ipoh’s famous pomelos shrinking in size, schoolchildren are also getting more obese with the sound advice from the authorities to stay indoors.

Presumably, many children will go in droves to air-conditioned malls and fast food restaurants for meals, which naturally will add to the problem of obesity.

Doctors say obesity is defined as the condition of being very overweight and having a body mass index, or BMI, of 30 or higher. The BMI is a measure of the weight relative to the height.

Evidently, obesity is manifested in the abdominal fat around the waist of children and adults as well.

But we should not get unduly worried with the adults because they are mature and knowledgeable enough to take responsibility for their health.

However, the innocent children’s health is undeniably our responsibility. Like it or not, we are accountable and answerable for the obesity problem in their adult life.

Today we can see the startling increase in the number of obese children across the country. Yet many parents unfortunately are seemingly too busy to check their children’s diet, let alone their daily exercise like the recommended walk of up to 10,000 steps a day.

Perhaps schools should voluntarily take up the task of creating awareness about the high risks and health hazards of obesity.

One practical way is to do routine short workouts: get students to burn calories by doing some exercises in the school assembly or in class every day – even some stretching exercises will suffice.

Certainly, this will increase their metabolic rate, thus strengthening their mental ability to learn; reducing levels of stress and depression; and suppressing the appetite.

When the heat wave is over, I would say it is the ethical and moral responsibility of the school authorities to bring back the Physical Standard Tests for all students like the good old days and mobilise all the staff to run selected athletic events such as the 100m, 200m, long jump, high jump and shot putt. Set certain standards for the events.

It would be much better if the Education Ministry’s Sports Department sets the national standards for all these events, which was done in the 60s till the 80s by using the co-curriculum 001 and 002 cards.

Next, it is also incumbent upon the Education Ministry to make it mandatory for school canteens to display the calorie counts for all the food so that the children will learn how to make healthy food choices and to calculate the total calorie intake they require for a day (about 1,600 and 2,500 calories per day depending on their age, gender and activity level).Eventually, they will “graduate” to become smart healthy consumers.

Let’s take these critical measures seriously to save our children from potential health risks like diabetes, high blood pressure, high cholesterol, heart disease and also some cancers.

This will invariably reduce the national health bill as well.

It was reported in “Putrajaya tops obese list” (see above) that we already have the highest percentage of overweight people in South-East Asia, and two out of five civil servants are obese.

Hence, invariably, the Government has to increase the health budget to cater for our increasingly ailing population if the obesity problem is not urgently addressed.

Scientists Finally Discover How the Obesity Gene Works



Scientists have finally figured out how the key gene tied to obesity makes people fat, a major discovery that could open the door to an entirely new approach to the problem beyond diet and exercise.

The work solves a big mystery: Since 2007, researchers have known that a gene called FTO was related to obesity, but they didn’t know how, and could not tie it to appetite or other known factors.

Now experiments reveal that a faulty version of the gene causes energy from food to be stored as fat rather than burned. Genetic tinkering in mice and on human cells in the lab suggests this can be reversed, giving hope that a drug or other treatment might be developed to do the same in people.

The work was led by scientists at MIT and Harvard University and published online Wednesday by the New England Journal of Medicine.

The discovery challenges the notion that “when people get obese it was basically their own choice because they choose to eat too much or not exercise,” said study leader Melina Claussnitzer, a genetics specialist at Harvard-affiliated Beth Israel Deaconess Medical Center. “For the first time, genetics has revealed a mechanism in obesity that was not really suspected before” and gives a third explanation or factor that’s involved.

Independent experts praised the discovery.

“It’s a big deal,” said Dr. Clifford Rosen, a scientist at Maine Medical Center Research Institute and an associate editor at the medical journal.

“A lot of people think the obesity epidemic is all about eating too much,” but our fat cells play a role in how food gets used, he said. With this discovery, “you now have a pathway for drugs that can make those fat cells work differently.”

Several obesity drugs are already on the market, but they are generally used for short-term weight loss and are aimed at the brain and appetite; they don’t directly target metabolism.

Researchers can’t guess how long it might take before a drug based on the new findings becomes available. But it’s unlikely it would be a magic pill that would enable people to eat anything they want without packing on the pounds. And targeting this fat pathway could affect other things, so a treatment would need rigorous testing to prove safe and effective.

The gene glitch doesn’t explain all obesity. It was found in 44 percent of Europeans but only 5 percent of blacks, so other genes clearly are at work, and food and exercise still matter.

Having the glitch doesn’t destine you to become obese but may predispose you to it. People with two faulty copies of the gene (one from Mom and one from Dad) weighed an average of 7 pounds more than those without them. But some were obviously a lot heavier than that, and even 7 pounds can be the difference between a healthy and an unhealthy weight, said Manolis Kellis, a professor at MIT.

He and Claussnitzer are seeking a patent related to the work. It was done on people in Europe, Sweden and Norway, and funded by the German Research Center for Environmental Health and others, including the U.S. National Institutes of Health.

“It’s a potential target” for drug development, said Dr. Sam Klein, an obesity researcher at Washington University in St. Louis. He called the work “an amazing study” and “a scientific tour de force.”

Dr. Rudolph Leibel, an obesity expert at Columbia University in New York, used the same term — “tour de force.” Still, some earlier research suggests the FTO gene may influence other aspects of obesity such as behavior and appetite.

“It’s possible there are several mechanisms being affected,” and that fat-burning is not the whole story, he said.
