by Bob Yirka, Medical Xpress Solar exposure enhances the energy intake and metabolic profile of men compared to women. a, Dot plot of the monthly energy intake (Kcal per day), from 1999 to 2001, of 2,991 men (cyan blue) and women (pink) (top). Midline represents the median. Data are presented as mean ± SD. Men’s energy consumption...

Credit: Kbradnam at English Wikipedia/Wikimedia Commons, CC BY-SA 2.5 Using four unrelated strains of the microscopic nematode C. elegans originating from different parts of the world, a group of worm biologists have developed a model system to study individual differences in metabolism. The use of C. elegans, a widely...

In brown fat cells, however, energy is dissipated as heat – brown fat thus serves as a biological heater. Most mammals therefore have this mechanism. In humans it...
by University of Basel Credit: CC0 Public Domain Even before carbohydrates reach the bloodstream, the very sight and smell of a meal trigger the release of insulin. For the first time, researchers from the University of Basel and University Hospital Basel have shown that this insulin release depends on a short-term inflammatory response that takes...
Stanford Medicine researchers and their collaborators have identified a molecule that staves off hunger post-exercise. Scientists are calling it the “anti-hunger” molecule. New research shows that a compound induced by intense exercise travels to the brain to stifle appetite. The molecule, identified by researchers at Stanford Medicine, Baylor University, and other institutions, helps demonstrate how exercise results in...
by Joslin Diabetes Center Credit: Unsplash/CC0 Public Domain More than 40 percent of American adults have obesity, a complex condition that can increase the risk of diabetes, cardiovascular disease and certain cancers. One mechanism by which obesity can lead to other health problems is by causing low-grade chronic inflammation, the accumulation of immune cells in...
by Mallory Locklear, Yale University Credit: CC0 Public Domain A new Yale study has found that the liver plays a major role in regulating feeding behavior in mice, a discovery that could have implications for people with eating disorders and metabolic diseases. The study, which was done in collaboration with colleagues in Germany, also adds...
by Columbia University Credit: Unsplash/CC0 Public Domain Columbia and MIT researchers are revealing the surprising reasons why cancer cells are often forced to rely on fat imports, a finding that could lead to new ways to understand and slow down tumor growth. The research, led by Dennis Vitkup, Ph.D., associate professor of systems biology at...
BAYLOR COLLEGE OF MEDICINE Researchers at Baylor College of Medicine, Stanford School of Medicine and collaborating institutions report today in the journal Nature that they have identified a molecule in the blood that is produced during exercise and can effectively reduce food intake and obesity in mice. The findings improve our understanding of the physiological processes that...

A study published in Nutrition, Metabolism and Cardiovascular Diseasesand conducted at the Faculty of Sport and Health Sciences of the University of Jyväskylä shows that menopausal state or blood estrogen...
