The number of people who are obese and suffer one or more of its associated health problems (including type 2 diabetes) is escalating dramatically. Researchers are seeking to identify new targets for therapeutics that could limit appetite and thereby obesity. A team of researchers, led by Scott Waldman, at Thomas Jefferson University, Philadelphia, has now uncovered one such potential target by studying the molecular control of appetite in mice. In the study, Waldman and colleagues found...

Researchers in the Hotchkiss Brain Institute (HBI) at the University of Calgary's Faculty of Medicine have uncovered a mechanism by which stress increases food drive in rats. This new discovery, published online this week in the journal Neuron, could provide important insight into why stress is thought to be one of the underlying contributors to obesity. Normally, the brain produces neurotransmitters (chemicals responsible for how cells communicate in the brain) called endocannabinoids that...

The act of eating may itself be a way to lose weight, according to a new study which claims that spending more time chewing your food more could cause you to eat less. Writing in the American Journal of Clinical Nutrition, Jie Li and colleagues at the Harbin Medical University in China, discovered that those who chew their food 40 times instead of a typical 15 would consume approximately 12-percent fewer calories, according to a report on the research by Eric Schultz of Reuters Health. In...

The past two decades have witnessed an epidemic spread of obesity-related diseases in Western countries. Elucidating the biological mechanism that links overnutrition to obesity could prove crucial in reducing obesity levels. In the July 26 issue of PLoS Biology, Dr. Dongsheng Cai and his research team at Albert Einstein College of Medicine describe a pathway that directs the brain to sense the body's glucose dynamics, and they find that a defect of this glucose sensing process contributes to...

(Ivanhoe Newswire) -- The past two decades have witnessed an epidemic spread of obesity-related diseases in Western countries. Elucidating the biological mechanism that links overnutrition to obesity could prove crucial in reducing obesity levels. Researchers found a pathway that directs the brain to sense the body's glucose dynamics, and they believe that a defect of this glucose-sensing pathway contributes to the development of obesity. The correction of this defect can normalize the whole...

(Ivanhoe Newswire)--For some time scientists have known the hormone leptin has acted in the brain to prevent obesity, but the mystery remains as to whether or not this is a natural weight loss treatment. Leptin has been described as our starvation hormone. It tells your brain when you have stored enough energy in your fat cells to engage in normal metabolic processes. Senior study author Dr. Bradford B. Lowell from Beth Israel Deaconess Medical Center and Harvard Medical School was quoted...

New human imaging studies implicate gut hormone in brain reward signals Research to be presented at the upcoming annual meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that ghrelin, a naturally occurring gut hormone, increases our willingness to pay for food, while simultaneously decreasing our willingness to pay for non-food items. Have you ever wondered about why you are willing...

(Ivanhoe Newswire) -- A team of scientists has found that addictive drugs may have hijacked the same nerve cells and connections in the brain that serve a powerful, ancient instinct: the appetite for salt. Their rodent research shows how certain genes are regulated in a part of the brain that controls the equilibrium of salt, water, energy, reproduction and other rhythms "“ the hypothalamus. The scientists found that the gene patterns activated by stimulating an instinctive behavior,...

Scientists find altering hormone levels changes cellular development in the brain In a study that increases the understanding of the link between fetal development and obesity later in life, researchers at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) found altering the levels of two common hormones, insulin and leptin, in utero changes the cellular development in the region of the brain that regulates appetite. Their study using fetal neural stem cells...

(Ivanhoe Newswire) -- A new molecular imaging agent that specifically targets estrogenic mechanisms in the brain to find out what effect an enzyme, aromatase, has on body mass index (BMI). Aromatase is necessary for the production of estrogen in tissues throughout the body, including the brain. According to the World Health Organization, an estimated 1.5 billion adults are overweight, and in 2010 nearly 43 million children under the age of five were overweight. "We used this imaging agent to...
