Is Obesity Overrated?

One of the biggest health-related stories within the past year has been concern over the growing epidemic of obesity in the US. There's no doubt that Americans are getting heavier... but now, a new group of researchers is arguing that the health risks associated with obesity are overstated, and that studies supporting those ideas are erroneous.

These researchers point to new studies that indicate increases in death rates from obesity are statistically insignificant, and argue that underweight people are at greater health risk than their overweight counterparts. They also cite studies disproving any connection between obesity and heart disease, and stress that tables such as the body mass index (BMI), which tells people their "healthy weight" based on their sex and height, are unrealistic and inaccurate measures (bodybuilders, for instance, typically have an "obese" BMI). Such charges are reflected in recent scholarly titles, including The Obesity Myth, by Paul F. Campos (Gotham Books, 2004); The Obesity Epidemic: Science, Morality and Ideology, by Michael Gard and Jan Wright (Routledge, 2005); and Obesity: The Making of an American Epidemic, by J. Eric Oliver (Oxford University Press, August 2005).

Moreover, these critics allege that much of the anti-obesity research is funded by the diet and pharmaceutical industries. "The war on fat," says author Paul F. Campos, "is really about making some of us rich."

Maybe some of the recent concerns about obesity sound paranoid, but this isn't to say that it's OK to cancel your gym membership and start super-sizing your meal portions. Somewhere, common sense has to intervene and strike a balance between starvation dieting and total neglect of one's body. Plus, much of the arguing on this subject appears to be taking on economic and even political overtones. Just as critics accuse anti-obesity researchers of being in bed with the diet industry, how closely might some of those be allied with the food and restaurant industries, who would very much like us to stop worrying about which foods make us fat?

Obesity is an important topic that requires much more study. This controversy simply marks an opening volley in what will surely be a long and brutal battle.

UPDATE: The Centers for Disease Control (CDC) has reiterated its position that obesity is indeed harmful. Specifically, the CDC wanted to clarify its position in light of one of its studies that revealed fewer obesity-related deaths than did previous studies. "What we don't want is for this debate to continue to confuse people," said CDC director Dr. Julie Gerberding. "Obesity and overweight are critically important health threats in this country. They have many adverse consequences."

Media Turn Up In Flight, and On the Menu

Electronic entertainment is turning up in some curious places these days. Or maybe not so curious...

Airlines -- even those that are cash-strapped -- are considering installing monitors for each seat, through which passengers can watch movies, play games, listen to music or even access the Internet. For a small fee, of course. Airlines see this as a profitable venture, even as they endure higher fuel prices and cut corners elsewhere. Says Song Airlines vice president Tim Mapes, "Once you put the capital onboard the plane, it's a one-time expense. It's making the investment provide the absolute best return possible."

Planes are a logical place for this kind of media. Passengers represent a captive audience who would likely find a $5 fee for a movie or the ability to check their e-mail quite reasonable. However, those looking to distribute electronic media are getting even more creative than that...

McDonald's recently launched a pilot of Blaze Net, a kiosk that allows patrons to burn CDs, download cell phone ringtones, and print digital photos. The kiosks have been deployed in several McDonald's in the Chicago area, where initial response has been "overwhelmingly positive," according to a McDonald's spokesperson. Restaurants in West Virginia and Florida are next on the pilot list.

Regardless of the success of Blaze Net, Mickey D's might want to take a cue from Nolan Bushnell, founder of Atari and creator of Pong, the great-granddaddy of all video games. Bushnell's latest venture, Media Bistro, allows patrons to watch TV, play video games and surf the Web while they eat -- providing high-tech versions of the booth-side mini juke boxes that have graced diners and soda shops since the 1950s. A few tweaks to make the games kid-friendly and feature all our favorite McDonaldland characters, and the concept sounds tailor-made for the Golden Arches.

Bushnell should know a thing or two about combining video games and food. After launching Atari, Bushnell founded Chuck E. Cheese...

A "Ginormous" List of "Confuzzling" Words

Well, maybe it's not all that ginormous, but it does contain the best words not in the Merriam-Webster dictionary. The hallowed dictionary publisher recently solicited suggestions for new and obscure words not in its pages, and the responses it received were clever, useful and fun. Among them:

  • confuzzled (adj): confused and puzzled at the same time
  • cognitive displaysia (n): the feeling you have before you even leave the house that you are going to forget something and not remember it until you're on the highway
  • phonecrastinate (v): to put off answering the phone until caller ID displays the incoming name and number
  • troddle (v): to wander around without knowing of doing so
  • snirt (n): snow that is dirty, often seen by the side of roads and parking lots that have been plowed

Maybe you won't use these words in everyday speech, but the exercise simply goes to show how language is dynamic and ever-changing.

Smart Lights

Recent advances in the application of light-emitting diode (LED) and solid-state electronics for lighting may lead to the development of "smart lights" that can adjust themselves to specific conditions and even communicate with one another.

A recent article in Science magazine describes how smart lights can save energy and money (using only 3 watts to deliver the light equivalent of a 60-watt conventional bulb), deliver optimum light quality at different times of the day, provide the best type of light to grow plants indoors, and even communicate with other devices through rapid bursts imperceptible to the human eye. For instance, brake lights on a car could send out a signal to the car behind it to slow down.

Don't look for smart lights to hit the market anytime soon, though. Researchers are still learning how to deliver quality LED light through all points on the spectrum.

Gadgets Define Kids' Social Status

There's nothing new about kids wanting to have stuff just because "everybody else" has it. Growing up in the modern world, after all, is all about trying to fit in and maintain one's social standing... and usually, doing that means having the right gear. These days, however, fitting in is a costly proposition, as gadgets like iPods, camera phones and portable DVD players become must-have fashion accessories for kids and teens.

Market researchers who study teen consuming habits have noted a significant shift in the way young people regard style. Whereas kids used to rely on clothes and hair to make a statement and define themselves, today's teens measure social status through high-tech devices. Many credit the stylish iPod for this change, but the now-ubiquitous cell phone has also surely played a role.

These marketers cite the "nag factor" in driving the purchase of these gadgets, placing much of the financial burden on parents and grandparents. Marketers also note that "gadget envy" cuts across all socioeconomic lines, affecting young people everywhere.

Are Researchers Relying Less on the Web?

Librarians, subject matter experts and professional research intermediaries who thought they might be made obsolete by the Web should be reassured by a new survey suggesting that netizens are relying on the open Web less for research. According to the survey conducted by Outsell, a firm that serves the information industry:

[P]eople who use the Internet in their jobs are starting to tire of going directly to the open Web. Just 67 percent say they go to the open Web for the information they need for the job, compared to 79 percent in 2001. They are increasingly more likely to rely on corporate intranets, colleagues, libraries, and other intermediaries.


The survey also found that users spend more time searching for information since 2001 (11 hours vs. 8 hours per week), and now spend the majority of their time (53%) searching for information as opposed to analyzing and applying it.

Granted, Outsell has a vested interest in promoting the services of professional researchers. However, they may well be on to something here. As more information becomes available on the Web, the harder it becomes to use general purpose search engines to locate specific, relevant information. Also, information workers are increasingly pressed for time, and are rediscovering tools that help them narrow their searches quickly, such as specialized databases, portals, and good old fashioned human librarians. The survey also points to potential business opportunities for researchers willing and able to help their clients locate valid information quickly.

A Nation of E-Mail Junkies

How many times a day do you check e-mail? Once, twice, several? Do you check it late at night? On weekends? On vacation?

If so, you have plenty of company. A new survey conducted by America Online and Opinion Research Corporation has found that many of us check our e-mail several times a day, after hours and even while on vacation.

The survey revealed that many of us check e-mail:

  • Several times a day (47%)
  • While on vacation (60%)
  • In the middle of the night (40%)
  • First thing in the morning (40%)
  • Right before bedtime (14%)

The survey also found that 26% of those surveyed haven't gone for longer than two to three days without reading their e-mail.

At first blush, this survey seems to reinforce the perception that America is a nation of workaholics. It makes sense, after all, as more of us enter the 24/7 workplace, and more of us work remotely. However, the survey also found that e-mail is used for personal use as much if not more so than for business. Thus, it illustrates how e-mail has become a fundamental part of our lifestyles, as much so as the phone and Web.
