Up to a million obese people will be offered weight-loss surgery on the NHS, under controversial new guidelines.
The National Institute for Health and Care Excellence (Nice) has ruled that all obese people who have been given a diagnosis of type 2 diabetes in the past decade should be considered for stomach bands and bypasses. …
Patient groups questioned how the health service would cope with the up-front cost, potentially running into billions of pounds, at a time when waiting lists for treatment have topped three million, the highest for six years. …
Last year, Google realized that its employees were eating too much free candy — M&Ms, specifically. So the company conducted a little experiment, and carefully tracked the results. Cecilia Kang, writing in the Washington Post, summaries:
What if the company kept the chocolates hidden in opaque containers but prominently displayed dried figs, pistachios and other healthful snacks in glass jars? The results: In the New York office alone, employees consumed 3.1 million fewer calories from M&Ms over seven weeks. That’s a decrease of nine vending machine-size packages of M&Ms for each of the office’s 2,000 employees.
The company has conducted similar experiments in an effort to reduce consumption of sugary drinks and encourage employees to consume less calories in the company’s cafeterias. “With a company as big as Google, you have to start small to make a difference. We apply the same level of rigor, analysis and experimentation on people as we do the tech side,” says Jennifer Kurkoski, a member of Google’s HR team.
We’ve blogged before about America’s rising obesity rate and how to fight it, but the battle may have just gotten a little easier. A new report from the Centers for Disease Control (CDC) shows obesity rates dropping for low-income preschool children in 19 states between 2008 and 2011. From the Wall Street Journal:
The obesity analysis, by the federal Centers for Disease Control and Prevention in Atlanta, was based on data from 11.6 million children age 2 to 4. The survey group included children eligible for federally funded programs of maternal and child health and nutrition, such as the Special Supplemental Nutrition Program for Women, Infants and Children, known as the WIC program.
The decline was greatest in the U.S. Virgin Islands, where the obesity rate in such children fell to 11% in 2011 from 13.6% in 2008. Drops of more than one percentage point were also seen in Florida, Georgia, New Jersey, Missouri, and South Dakota.
Thomas Frieden, director of the CDC, called the results a “bright spot” and a “tipping point.”
“For the first time in a generation, we’re seeing it go in the right direction in 2- to 4-year-olds,” he said on a conference call with reporters, calling the changes “small but statistically significant.” He was quick to add, “We’re very, very far from being out of the woods.”
Of the 43 states measured, obesity rates for preschool children rose in 3 states and remained the same same in 21 states.
We’ve blogged before about the obesity epidemic, and whether or not it is a recent phenomenon; John Komlos and Marek Brabec have argued that obesity rates actually began rising in the early 20th century. A new study (abstract; PDF) by Paul von Hippel and Ramzi Nahhas looks at 60 years of data on child obesity and finds that the increase in obesity rates started with children born in the 1970s and 1980s. Von Hippel wrote to us in an email:

Intrigued by the conflicting extrapolation results, Ramzi Nahhas and I decided to look at measurements that were actually taken before 1960. We analyzed the heights and weights of children in the Fels Longitudinal Study, an ongoing study that since the 1930s has measured children from shortly after birth until age 18. Most of the children come from the area near Dayton, Ohio, which is not a mirror of the nation but has an obesity rate that is close to the national average.
“Our findings suggest that increases in the real price of one calorie in food for home consumption and the real price of fast-food restaurant food lead to improvements in obesity outcomes among youths. We also find that an increase in the real price of fruits and vegetables has negative consequences for these outcomes.”
Our recent Freakonomics Radio podcast “100 Ways to Fight Obesity” looked at some of the social costs of America’s increasing rate of obesity. One airline in Samoa is experimenting with defraying some of those costs. It will soon start charging passengers by the kilogram. From The Sydney Morning Herald:

Samoa Air has become the world’s first airline to implement “pay as you weigh” flights, meaning overweight passengers pay more for their seats.
“This is the fairest way of travelling,” chief executive of Samoa Air, Chris Langton, told ABC Radio. “There are no extra fees in terms of excess baggage or anything – it is just a kilo is a kilo is a kilo.”

I just listened to your podcast on 100 ways to fight obesity and while I think there were many quality ideas presented, too many neglected the bodybuilder or strength athlete. I am a lightweight strongman competitor and sometimes eat 10,000 calories in a span of 3-4 hours after training for 5+ hours. These meals are generally high in sugar to support the lost muscle glycogen from my day’s training. I am concerned that once you begin classifying foods as “good” or “bad” you burden people who you did not intend to. The government also does such a poor job with their diet recommendations; I wouldn’t trust them with anything regarding food and diet.
I do love the idea of teaching families and children at school about being malnourished. Unfortunately, I see this as just another way for junk food to add in some vitamins and tell you that you can meet your daily intake just eating their products. Ultimately, people need to wake the hell up and realize that they need to do their own research (not just read a magazine) and determine the right diet for their family.

Steve Levitt runs a consulting firm called The Greatest Good. It is occasionally hired by a philanthropist or foundation to look into societal problems. That’s what happened recently, when the Robert Wood Johnson Foundation asked The Greatest Good to put together a brainstorming session on childhood obesity. Stephen Dubner moderated the event. In this podcast, you get to be a fly on the wall as a dozen participants explore the biological, behavioral, political and economic angles of obesity. Read More »
