According to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM), the levels of appetite hormones in the body prior to dieting may serve as a predictor of weight regain after dieting. "Treating obesity with drugs or dietary programs can be very effective...

There is now another good reason to exercise. Besides burning calories, exercise restores the sensitivity of neurons involved in the control of satiety (feeling full), which in turn contributes to reduced food intake and consequently weight loss. This is the conclusion of a study led by Brazilian researchers at the University of Campinas, and the findings will be published next week in the online, open access journal PLoS Biology. This disclosure may bring hope to over 40% of the population...

A nutrient that's common to all living things can make hibernating marmots hungry - a breakthrough that could help scientists understand human obesity and eating disorders, according to a new study by a Colorado State University biologist. The study appears in the current issue of the Journal of Experimental Biology. Professor Greg Florant discovered he could slowly release a molecule called AICAR into yellow-bellied marmots that activates a neurological pathway driving food intake and...

In gastric cancer patients who have had part or all of their stomach removed, the hormone ghrelin may lessen post-operative weight loss and improve appetite, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. "It is our obligation to invent novel procedures to minimize the side effects of gastrectomy. Our study provides convincing data for the beneficial effects of ghrelin "” the only gastrointestinal...

Scientists at the University of Liverpool argue that anti-obesity drugs fail to provide lasting benefits for health and wellbeing because they tackle the biological consequences of obesity, and not the important psychological causes of overconsumption and weight gain. Dr Jason Halford, Reader in Appetite and Obesity at the University of Liverpool, points out that anti-obesity drug developers focus primarily on weight loss as their end goal, and do not take into consideration the motivational...

Universite de Montreal research team developing leptin-based pill to control hunger A Universit© de Montr©al research team is developing a pill composed of leptin, the protein that tells our brain to stop eating. "Mice deprived of leptin will not stop eating. They become so big they have trouble moving around," says Moïse Bendayan, a pathology professor at the Universit© de Montr©al Faculty of Medicine who has studied the leptin protein...

A Faculty of 1000 evaluation examines how a stomach-produced hormone that influences the desire to eat and consume alcohol could be switched off to control drinking problems. The study, carried out by Jerlhag et al. at the University of Gothenburg in Sweden, showed that the hormone ghrelin, typically released by the stomach and known to promote appetite and therefore the intake of food, also influences the consumption of alcohol. The results, published in The Proceedings of the National...

A major U.S. research study has pointed to a potential link between high levels of an appetite-curbing hormone and a lower incidence of Alzheimer's disease, offering new insights into the degenerative disease and possibly pointing out the path to new methods of treatment. The study, which was reported Wednesday in The Journal of the American Medical Association (JAMA), examined 200 volunteer patients over a 12-year period and found that subjects with the highest levels of the...

Persons with higher levels of leptin, a protein hormone produced by fat cells and involved in the regulation of appetite, may have an associated reduced incidence of Alzheimer disease and dementia, according to a study in the December 16 issue of JAMA. Previous studies have shown that overweight and obesity in mid-life are associated with poorer cognitive function in the general population and an increased risk of dementia. There has been evidence that leptin exerts additional functions on...

Ghrelin, a hormone produced in the stomach, may be used to boost resistance to, or slow, the development of Parkinson's disease, Yale School of Medicine researchers report in a study published in a recent issue of the Journal of Neuroscience. Parkinson's disease is caused by a degeneration of dopamine neurons in an area of the midbrain known as the substantia nigra, which is responsible for dopamine production. Reduced production of dopamine in late-stage Parkinson's causes symptoms such as...
