Should we sleep more to lose weight?

10.07.2012
Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that sleep behavior affects body weight control and that sleep loss has ramifications not only for how many calories we consume but also for how much energy we burn off.

In recent years an increasing number of epidemiological studies have found a relationship between how long we sleep for and obesity as well as type 2 diabetes, suggesting that insufficient sleep increases the risk of gaining weight and developing diabetes.

Work carried out by researchers from the German Universities Tubingen and Lubeck and Uppsala University in Sweden has investigated the effect of short term sleep deprivation on hunger as well as on physical activity and energy used by the body. Physical activity was measured by special devices worn on the wrist that detect acceleration. Energy used by the body was assessed by indirect calorimetry, a method which estimates how much heat is produced by a person as they use oxygen.

Sleep deprivation increased how hungry participants felt and also raised the amount of the "hunger hormone" ghrelin detected in their blood. In fact, the shorter the amount of sleep a person had experienced the hungrier they were. After just one night of disrupted sleep volunteers moved around less although this was not surprising considering they also felt more tired. In addition, staying awake for one complete night reduced the amount of energy used by the body when resting. This research tells us when we are sleep deprived we are likely to eat more calories because we are hungrier. This alone might cause us to gain weight over time. However sleep loss also means we burn off fewer calories which adds to the risk of gaining weight.

Ongoing studies aim to find out if increasing sleep time might help with weight control efforts. While there is still some way to go before sleep improvement is used to treat obesity and diabetes, the available research results clearly supports the notion that sleep is involved in the balance between the amount of calories we eat and the amount we use up through activity and metabolism.

The research was funded by the German Research Foundation (DFG).

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
