Women with weight problems were more impulsive than average in a food-related psychology test, a new research paper has shown.
This suggested that they are more instinctively stimulated by images of food as well as lacking contemplative will power. Further, some women reported food craving even if they had eaten recently, a symptom of possible food addiction.
“All addictions are similar in that the sufferer craves to excess the feel-good buzz they receive from chemical neurotransmitters produced when they eat, gamble, smoke, have sex or take drugs,” commented Claus Voegele, Professor of Clinical and Health Psychology at the University of Luxembourg.
In this original test, images of fatty or sweet food (a burger, cake, pizza etc.) and non-food items (a sock, a mug, a shoe etc.) were flashed at random on a computer screen. The women were instructed to click as fast as possible on either the food or non-food pictures. The women with weight problems performed less well than the average.
Tests were run either three hours after eating or just after meals. The researchers at the University of Luxembourg and the University of Würzburg (Germany) found that several women with weight problems said the test had provoked food craving, regardless of how recently they had eaten.
“This suggests that some people may have an instinctive, psychological predisposition to binge eating,” Prof. Voegele said.
He pointed to other research which indicates both nature and nurture are at the root of this condition. “People may over-eat to comfort themselves, because they are bored or just out of habit,” he said. At the other end of the spectrum, those with excessive control may suffer disorders such as anorexia nervosa.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
