Extending sleep duration may help to reduce overeating A new study suggests that increasing the amount of sleep that adults get could lead to reduced food intake, but the hormonal process differs between men and women. "Restricting sleep in healthy, normal weight participants has limited effects on metabolic risk factors and may affect food intake regulating hormones differently in men and women," said Marie-Pierre St-Onge, PhD, FAHA, the study's principal investigator. "We were...

Obesity is a chronic metabolic disorder that affects half a billion people worldwide. Managing obesity is difficult, as many patients rebound to their pre-treatment weight. There is a hypothesis that chronic weight gain causes the body to adopt a state that supports excess weight. In a study published in the Journal of Clinical Investigation, researchers led by Malcolm Low at the University of Michigan challenged this hypothesis by developing a mouse model of obesity where the...

Swimming With Hormones Ancient Urges That Drive The Social Decisions Of Fish Unraveled

Researchers have discovered that a form of oxytocin–the hormone responsible for making humans fall in love–has a similar effect on fish, suggesting it is a key regulator of social behavior that has evolved and endured since ancient times. The findings, published in the latest edition of the journal Animal Behaviour, help answer an important evolutionary question: why do some species develop complex social behaviors while others spend much of their lives alone? "We know how...

Researchers at The Scripps Research Institute have found new links between a protein that controls our urge to eat and brain cells involved in the development of alcoholism. The discovery points to new possibilities for designing drugs to treat alcoholism and other addictions. The new study, published online ahead of print by the journal Neuropsychopharmacology, focuses on the peptide ghrelin, which is known to stimulate eating. “This is the first study to characterize the effects...

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...

Prenatal exposure to the environmental contaminants polychlorinated biphenyls, or PCBs, causes long-term changes to the developing brain that have adverse effects on reproductive function later in life, a new study finds. Results will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston. The study used rats, whose genes and molecules in the hypothalamus–the region of the brain important for reproductive function–are virtually identical to those in...

A pre-diet measurement of two hormones related to weight regulation can help predict which dieters will be more likely to maintain their weight loss and who will not, according to a new study. The results will be presented Sunday at The Endocrine Society's 94th Annual Meeting in Houston. With obesity rates in many countries steadily climbing, more people are turning to diets to lose weight. But, for many people, maintaining the weight loss can be extremely difficult, leading to a...

A new study suggests that the appetite-inducing hormone ghrelin increases the incentive for humans to eat high-calorie foods, even on a full stomach. The results will be reported Sunday at The Endocrine Society's 94th Annual Meeting in Houston. In the study, rats lacking the ghrelin receptor gene ate less of a sweet treat after a full meal than did rodents whose ghrelin receptor gene was intact. "Combined with an increasingly sedentary lifestyle, overconsumption of reward-driven foods...

Normally, male California mice are surprisingly doting fathers, but new research published in the journal Physiological and Biochemical Zoology suggests that high anxiety can turn these good dads bad. Unlike most rodents, male and female California mice pair up for life with males providing extensive parental care, helping deliver the pups, lick them clean, and keep them warm during their first few weeks of life. Experienced fathers are so paternal that they'll even take care of pups that...

Labor Induction is a process of giving an artificial start to birth with medical intervention or other methods. When an induction is not performed for emergency or other medical reasons, the method is considered an elective process. The decision to induce labor has increased in recent years due to its convenience or because it easily accommodates busy schedules. The American College of Obstetricians and Gynecologists, however, say that labor should only be induced when it is more risky...
