Because they use internal cues -- such as no longer feeling hungry -- to stop eating, reports a new Cornell study. Americans, on the other hand, tend to use external cues -- such as whether their plate is clean, they have run out of their beverage or the TV show they're watching is over.
"Furthermore, we have found that the heavier a person is -- French or American -- the more they rely on external cues to tell them to stop eating and the less they rely on whether they felt full," said senior author Brian Wansink, the John S. Dyson Professor of Marketing and director of the Cornell Food and Brand Lab in the Department of Applied Economics and Management, now on leave to serve as executive director of the U.S. Department of Agriculture's Center for Nutrition Policy and Promotion until January 2009.
The new study, an analysis of questionnaires from 133 Parisians and 145 Chicagoans about how they decide when to stop eating, is being published in the journal Obesity and is being presented this later month at an the Winter Marketing Educators conference.
"Over-relying on external cues to stop eating a meal may prove useful in offering a partial explanation of why body mass index [a calculation based on the relationship of weight to height] varies across people and potentially across cultures," said co-author Collin Payne, a Cornell postdoctoral researcher.
He stressed that further studies should following up with smoking behavior and socio-economic differences as well. "Relying on internal cues for meal cessation, rather than on external cues, may improve eating patterns in the long term.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
