Without being aware of it, the researchers believe, human beings keep up with the weight of the Joneses. For a whole society, this can lead to a spiral of imitative obesity. The researchers will present their results on Friday July 25th at a National Bureau of Economic Research conference in Cambridge Massachusetts in a paper entitled Imitative Obesity and Relative Utility at the NBER Summer Institute on Health Economics.
Using data on 27,000 Europeans from 29 countries, the researchers find that nearly half of European women feel overweight. Less than a third of males feel overweight.
The authors suggest that whether for reasons of job promotions or finding a mate it is someone’s weight relative to others that matters. They show that overweight perceptions and dieting decisions are influenced by people’s comparisons with others of the same age and gender.
Highly educated Europeans hold themselves to a particularly tough standard, the research shows. For any given level of Body Mass Index (BMI), somebody with a university degree feels much fatter than someone with low educational qualifications.
Overall, the researchers believe that a person’s "utility" (an economic term roughly meaning satisfaction levels) depends on their own weight relative to the weight of those around them. They suggest that it is easier to be fat in a society that is fat.
However, the authors also found a significant gender split. Females were much more prone, for any given BMI value, to feel overweight. For European women, weight dissatisfaction and overweight perceptions depended crucially upon not just their own absolute BMI, but also upon their BMI relative to other women of exactly the same age in their country. Conversely, being overweight tended not to be a significant issue for men if many of those around them were as overweight as they were.
Professor Andrew Oswald at the University of Warwick, one of the researchers, said "Consumption of calories has gone up but that does not tell us why people are eating more. Some have argued that obesity has been produced by cheaper food, but if fatness is a response to greater purchasing power, why do we routinely observe that rich people are thinner than poor people?"
He said: "A lot of research into obesity, which has emphasized sedentary lifestyles or human biology or fast-food, has missed the key point. Rising obesity needs to be thought of as a sociological phenomenon not a physiological one. People are influenced by relative comparisons, and norms have changed and are still changing."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
