For Fitness Bands, Slick Marketing but Suspect Results

My Nike FuelBand read lazy. My friend’s read fit.

But we had done essentially the same thing. We spent the day walking around San Francisco together — the same number of miles, same number of hills — but for whatever reason, our FuelBands were out of step. His registered thousands of steps more than mine did.

That’s the uncomfortable truth about many of the fitness wristbands you see people wearing. They don’t really work — or at least not as well as their manufacturers would have you believe.

So maybe it is no surprise that Nike laid off a big part of its FuelBand team this month. As other companies dive into wearable devices, Nike is pulling back. Why? Nike told me the FuelBand would remain an important part of its business, but the company would be focusing on apps, not hardware.

The reality is that many devices claiming to monitor fitness and health probably overpromise and underdeliver. Jim McDannald, a podiatrist and health and fitness technology writer at The Wirecutter, a technology testing website, said many of these devices are more about marketing than medical understanding.

”People are getting fitness-tracker fatigue,” Mr. McDannald told me. In large part, it’s because many of these devices are simply inaccurate. You may have burned more — or fewer — calories than they say. Or, in my case, walked more steps.
“Even a cheap pedometer is more accurate than these wristband trackers,” Mr. McDannald said, though he acknowledged that wristbands do push people to get up off the couch.

And don’t get him started on sleep trackers. His take on those devices: “ridiculous.” The only one he has found that works well is the Basis B1 band, which has a built-in heart-rate monitor. The rest, he said, rely mostly on guesswork.
Tell me about it.

I’ve tested the Jawbone Up, which can track your movements and your sleep. While the step-counter is one of the best I have seen, after I spent a restless night searching for sheep to count, the band told me I had slept for a blissful eight hours.

The Well Guide to Activity Trackers

We tested some of the latest and most popular trackers to compare how they work and the various features they offer. Here’s what we found.

Whatever their accuracy, these monitors have plenty of takers. According to a report by Canalys, the market research firm, more than 17 million wearable devices, including smart watches and fitness bands, are expected to be sold in 2014 alone. The report estimated that hardware makers would sell 23 million by 2015 and over 45 million by 2017.

“Though currently a relatively small market serving fitness enthusiasts, wearable bands represent a massive opportunity in the medical and wellness segment,” the Canalys report predicted.

And yet.

To see if this was a hardware problem with a software solution, I recently tested two apps, Breeze and Moves, that claim to track the number of steps you take using a sensor in an Apple iPhone. One day, Moves said I had walked 3,070 steps, while Breeze said I had taken 3,363. Same iPhone, different results.

Another day, Breeze told me I had hit my daily goal — 3,500 steps — while I was sitting motionless in my cubicle. A different time, I somehow managed to reach my daily goal while I was driving.

Some devices promise more, claiming to monitor vital health signs. Healbe, for instance, says that its GoBe band can read glucose levels through the skin.

I asked the marketing team for the company, which recently raised $1 million in financing, how the wristband could accurately monitor blood sugar without drawing a drop of blood. They acknowledged that the product wasn’t completely precise.

“We’re not touting this as a medical device,” said a spokesman. “We don’t want diabetics using this product.”

Fine. But the company’s sales page makes several promises that espouse the device’s accuracy. Some people have questioned the GoBe, noting that many of its claims appear scientifically impossible.

DESCRIPTION

What Your Activity Tracker Sees and Doesn’t See

High-tech fitness and activity trackers all share one thing: an accelerometer. Here’s how they work — and don’t.

One company everyone seems to be waiting for in this field is Apple. It has been working on a wrist device that is expected to integrate health statistics and tracking.

As I reported with my colleague Brian Chen, a group of Apple executives met with directors at the Food and Drug Administration in December to discuss mobile medical applications, according to the F.D.A.’s public calendars, which list meeting participants.

Apple has also hired several people with expertise in medical sensors, including Michael O’Reilly, the former chief medical officer of the Masimo Corporation, which makes medical monitoring devices.

“These technologies will have enormous potential over time, but I think their full potential will take many years to realize,” said Dr. David Blumenthal, a former adviser to President Obama and president of the Commonwealth Fund, a New York-based foundation that focuses on health care. “In pioneer analogies, we’re just landing on Plymouth Rock.”

And for the moment, at least, the accuracy of many health wristbands is not exactly rock solid.

Shivering, Like Exercise, May Help Boost Weight Loss

When you shiver, your body converts white fat to healthier brown fat, study finds

Shivering, Like Exercise, May Help Boost Weight LossWEDNESDAY, Feb. 5, 2014 (HealthDay News) — If frigid weather is making you shiver, there’s an upside — it might also help you burn calories. Both moderate shivering and moderate exercise may convert bad white fat into healthier brown fat, a new study says.

White fat stores calories while brown fat burns them. For example, 50 grams of white fat stores more than 300 calories of energy, while the same amount of brown fat can burn up to 300 calories a day, explained researchers who conducted the study at the U.S. National Institutes of Health (NIH).

The study authors said their findings may lead to ways to activate brown fat so as to fight obesity and diabetes.

The investigators found that moderate exercise or shivering from being cold increased people’s levels of the hormones “irisin” (produced by muscle) and “FGF21” (produced by brown fat). Rises in irisin levels after 10 to 15 minutes of shivering were about the same as after an hour of moderate exercise on a stationary bicycle.

Laboratory tests showed that irisin and FGF21 turned human white fat cells into brown fat cells over six days, according to the study published Feb. 4 in the journal Cell Metabolism.

This ability to crank up metabolism has important health implications, the researchers suggested.

“Excitement in the brown fat field has risen significantly over the last few years because its energy-burning nature makes it a potential therapeutic target against obesity and diabetes,” Dr. Paul Lee, an endocrinologist from the Garvan Institute of Medical Research in Australia, said in an institute news release.

“White fat transformation into brown fat could protect animals against diabetes, obesity and fatty liver. Glucose [blood sugar] levels are lower in humans with more brown fat,” explained Lee, who conducted the study while at the NIH.

Babies have brown fat to help keep them warm. Until recently, it was thought that brown fat was lost in early infancy, but it’s now known that most or all adults still have brown fat, according to the news release. Adults with more brown fat are thinner than those with less of it.

“We speculate exercise could be mimicking shivering — because there is muscle contraction during both processes, and that exercise-stimulated irisin could have evolved from shivering in the cold,” Lee said.

FAT CITY – What can stop obesity?

Why obesity is not your doctor’s problem.

In the late 1980s I spent a year in the US as an exchange student. The exchange organisation allocated me a local support person named Emily. Emily was white and loud and the fattest person I had ever seen outside a caravan park. She looked different from the rare very fat people I’d seen in Australia. She smelt good and her climate-controlled house meant she did not sweat. She was very well dressed. Her husband was some kind of professional; I didn’t know they even made suits that big.

Emily’s family ate like the bejesus. I went to her house once a month for pizza: heavy, oily discs of cheese half a metre across. One each. Before pizza one night I watched the daughter eat a huge bowl of guacamole with a dessertspoon. I couldn’t take my eyes off her. I had no concept of calories; I’d simply never seen anyone eat so much avocado in one sitting. I wondered if it would make her vomit. I kept watching as she put down the empty bowl and turned the page of her novel.

I loved Emily. She cared for me the same way she ate: enthusiastically, generously, without restraint. Her bulk did not disgust me. But I never once ate any pizza. The thought of her pizzas made me sick. All those pools of fat. Twenty-five years later I am a physician and Australia is filling up with Emilys.


Louise was an educated 35-year-old who had recently lost her high-ranking job and was making ends meet by freelance consulting. Admitted to my ward with pneumonia, she had a high fever and a fast pulse, needed oxygen and was coughing up large amounts of purulent sputum. She was also fat, weighing about 120 kg. I knew that – barring underlying lung disease – obesity was one of the greatest risk factors for life-threatening pneumonia in young people. I felt a responsibility to tell her that her excess fat had harmed her in a way she may not have realised. Every day before my ward round I would say to myself that I was going to broach the subject with her. It seemed a good opportunity to intervene. And yet each time I stood by her bed and looked at her bedside table piled high with literary novels, open blocks of chocolate and teddy-bear biscuits, each time I lifted her pyjama top and pushed my stethoscope into her soft white flesh, I couldn’t do it. I was embarrassed to mention her weight; it felt like I was a puritan taking the high moral ground. It felt mean.

As a doctor, I no longer know what to do about the obese. Australians are getting fatter, and our society is geared towards making them that way – consumption doesn’t just drive economic growth. So is fatness a doctor’s problem? Studies show that verbal interventions during an episode of serious acute illness can result in a change in behaviour – people quit smoking, cut down on their drinking and sometimes lose weight. But usually counselling people to lose weight is hopeless. Then there are the questions of morality, personal responsibility, associated diseases, resource allocation, quality of life and aesthetics. I have moments of clarity – I think of the way Emily ate – and obesity seems simple: more in than out. Then I am engulfed once again by the high science of genetics, by the concept that obesity is a disease.


I love reading articles with titles like ‘How I Lost 25 Kilos’, even though the answer is always the same: I ate less. Barring the gravely ill and a couple of men, everyone I know wants to lose weight. We live in a society that judges people for being fat, yet has in place every possible means for making them so. Who wants to eat less – of anything – when food is so good and plentiful? It’s hard to say no to something that is right in our faces, promising a bit of easy pleasure. It is especially hard to say no when the consequences of overeating come about in such a distant, gradual and mysterious way. I find it difficult to believe that an extra scoop of ice-cream will end up as fat somewhere on my body, even though I know how it happens at the enteric, metabolic and cellular levels. Perhaps this is what happens when we reach the head of the queue and order too much: a fantasy where eating has no consequence, where that pile of French fries and the burger with extra cheese are not our future bodies.

Battles with our appetites and with our bodies are played out on television, in magazines, in the workplace, in families and in hospitals. Be fat in public and you will be weighed by strangers’ eyes. The most radical thing on television this past year Read more Wednesday 131204

Are Most People in Denial About Their Weight?

As I was walking through the gym the other day, I caught a glimpse of an overweight woman across the room. But then I did a double take, and then another. The woman was me — I had seen my own reflection in a distant mirror and, for a split second, hadn’t recognized myself.

This moment of mistaken identity was disconcerting, but it wasn’t all that unusual. Many of us are surprised by our size when reflected in the mirror or a store window — it’s like thinking that a recording of your own voice sounds off. And while psychologists have worried for years that media images of superslim starlets would put the nation’s collective self-esteem at risk, it turns out that something altogether different has happened. As the population becomes fatter, study after study shows that instead of feeling bad about ourselves, we have entered a collective state of denial about how big we’re actually getting.

A team of researchers led by a group from the University of Illinois at Urbana-Champaign recently asked 3,622 young men and women in Mexico to estimate their body size based on categories ranging from very underweight to obese. People in the normal weight range selected the correct category about 80 percent of the time, but 58 percent Read more Wednesday 120425
