Sleeping less may be related to weight gain

11.01.2005


Lack of sleep could make you fat. In an editorial published in the Jan. 10 issue of the Archives of Internal Medicine, two Northwestern University researchers stress the need to better understand the growing epidemic of obesity in the United States by studying how loss of sleep alters the complex metabolic pathways that control appetite, food intake and energy expenditure.



Commenting on two obesity studies also published this week in the journal, Joseph Bass, M.D., assistant professor of medicine, and Fred W. Turek, Charles E. and Emma H. Morrison Professor of Biology and director of Northwestern’s Center for Sleep and Circadian Biology, write: "In recent years, a new and unexpected ’obesity villain’ has emerged, first from laboratory studies and now, as reported by Vorona et al in this issue of the Archives, in population-based studies: insufficient sleep. However, while there is a growing awareness among some sleep, metabolic, cardiovascular, and diabetes researchers that insufficient sleep could be leading to a cascade of disorders, few in the general medicine profession or in the lay public have yet made the connection."

As younger and older Americans alike struggle with an inability to get enough sleep and to control weight, the authors stress the need to investigate whether intervention in sleep disorders could help reduce obesity’s negative effects on metabolism and health. In commenting on a second article appearing in the same issue of the Archives, Bass and Turek note that even school age American children are not obtaining enough sleep and that sleep loss during the formative years of life could be putting our youth on a trajectory toward obesity and the metabolic syndrome.


Obesity is associated with metabolic and cardiovascular disorders often referred to as the metabolic syndrome, which increases an individual’s risk of developing a serious disease, say Bass and Turek. In addition to excess body weight, factors include high blood pressure, high insulin levels and one or more abnormal cholesterol levels. According to the Mayo Clinic, as many as one in four American adults and 40 percent of adults age 40 or older have metabolic syndrome, an increase of 61 percent over the last decade.

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
