Metformin may reduce food intake and body weight, but the anorexigenic effects of metformin are still poorly understood. Under normal physiological conditions, Prof. Zheng Zhao and his team from the Key Laboratory of Brain Functional Genomics, Ministry of Education, China observed the changes in food intake after administration of metformin. They found that the central administration of metformin significantly reduced food intake and body weight gain, and a reduction of neuropeptide Y...

New research in the FASEB Journal suggests that the neuropeptide Y in plasma and its Y2 receptor in visceral fat play an important role in obesity A new report involving mice suggests that a relationship exists between maternal metabolic or psychological stress and the development of obesity, type 2 diabetes, and metabolic syndrome in her offspring. What's more, the report shows that if the stress cannot be reduced or eliminated, manipulating the neuropeptide Y (NPY) system in visceral fat...

Feeling full involves more than just the uncomfortable sensation that your waistband is getting tight. Investigators reporting online on July 5th in the Cell Press journal Cell have now mapped out the signals that travel between your gut and your brain to generate the feeling of satiety after eating a protein-rich meal. Understanding this back and forth loop between the brain and gut may pave the way for future approaches in the treatment and/or prevention of obesity. Food intake can be...

(Ivanhoe Newswire)-- A ravenous appetite may be what causes many overweight people to be obese. Researchers have found a mutation in a single gene is responsible for the inability of neurons to effectively send out appetite suppressing signals from the body to the correct area of the brain. A study suggests that there might be a way to stimulate expression of that gene to treat obesity caused by uncontrolled eating. Researchers found that a mutation in the brain-derived neurotrophic...

[ Watch the Video ] A male, his affections spurned by a female that he's attracted to, is driven to excessive alcohol consumption. The story may be familiar, but in this case, the lead characters aren't humans -- they're fruit flies. Researchers from the University of California, San Francisco (UCSF), have discovered that like their Homo sapiens counterparts, male members of the species Drosophila melanogaster tend to, for lack of a better term, "get drunk" after being rejected by...

Although the study was done in rats, scientists suggest the findings could help explain why many users of the therapy report health benefits Acupuncture significantly reduces levels of a protein in rats linked to chronic stress, researchers at Georgetown University Medical Center (GUMC) have found. They say their animal study may help explain the sense of well-being that many people receive from this ancient Chinese therapy. Published online in December in Experimental Biology and...
