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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
