A new study suggests that eating your food at a fast pace blocks the body's natural appetite-control process. "Most of us have heard that eating fast can lead to food over consumption and obesity, and in fact some...studies have supported this notion," Dr. Alexander Kokkinos, the lead researcher on the study, said in a written statement. According to Kokkinos and his colleagues at Athens University Medical School in Greece and the Imperial College London in the U.K., what has been missing is...

According to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM), eating a meal quickly, as compared to slowly, curtails the release of hormones in the gut that induce feelings of being full. The decreased release of these hormones, can often lead to overeating. "Most of us have heard that eating fast can lead to food overconsumption and obesity, and in fact some observational studies have supported this notion," said...

The link between obesity and osteoarthritis may be more than just the wear and tear on the skeleton caused by added weight. A Duke University study has found that the absence of the appetite hormone leptin can determine whether obese mice experience arthritis, no matter how heavy they are. "We were completely surprised to find that mice that became extremely obese had no arthritis if their bodies didn't have leptin," said Farshid Guilak, Ph.D., director of orthopaedic research in the Duke...

Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain, according to a recent study published in Cell by Yale School of Medicine researchers and colleagues at Columbia University. This new finding contradicts the view that leptin acts primarily in the hypothalamus. "Our study challenges the view that the hypothalamus is the...

Leptin-serotonin pathway offers new clues for obesity and osteoporosis prevention New research from Columbia University Medical Center has illuminated a previously unknown leptin-serotonin pathway in the brain that simultaneously promotes appetite and bone mass accrual. The research, which explains how leptin "“ well-known appetite-suppressing hormone "“ acts in the brain, is published in the Sept. 4 issue of Cell. When the leptin-serotonin pathway is turned on in mice, the...

Some of the first information about how fat causes hypertension have been identified by researchers who say the findings should one day help identify which obese people "“ and maybe some thin ones too "“ are at risk for hypertension and which drugs would work best for them.Medical College of Georgia researchers have found that deleting or mutating the gene PTP1B puts mice at risk for hypertension by interfering with an endogenous mechanism that should help prevent it. The findings...

As we all know from experience, people eat not only because they are hungry, but also because the food just simply tastes too good to pass up. Now, a new study in the August 6th Cell Metabolism, a Cell Press publication, helps to explain how leptin, a hormone produced by fat tissue, influences that motivation to eat.The researchers describe for the first time a new bunch of leptin-responsive (LepRb) neurons in the brain's lateral hypothalamic area (LHA). Those LHA neurons feed directly into...

Having trouble losing weight and keeping your type 2 diabetes under control? A key enzyme in the brain may be behind the difficulties. A new study shows decreasing the levels of the brain enzyme prolylcarboxypeptidase (PRCP) led to weight loss and a decreased risk of type 2 diabetes. Researchers studied mice and found  PRCP is located in the hypothalamus. PRCP regulates levels of the alpha-melanocyte stimulating hormone alpha-MSH, which is a peptide known for inhibiting food intake and...

In a major advance in obesity and diabetes research, Yale School of Medicine scientists have found that reducing levels of a key enzyme in the brain decreased appetites and increased energy levels.Reductions in the levels of the enzyme prolylcarboxypeptidase (PRCP) led to weight loss and a decreased risk of type 2 diabetes in mice, according to research published in the August issue of the Journal of Clinical Investigation. The team found that PRCP is located in the hypothalamus and regulates...

The peptide alpha-MSH works in a region of the brain known as the hypothalamus to suppress appetite. A team of researchers, at Yale University School of Medicine, New Haven, and the University of California Davis, has provided new insight into the way in which levels of the active form of alpha-MSH are regulated in mice. Specifically, genetic and biochemical analysis performed by the team, led by Sabrina Diano and Craig Warden, indicated that the protein PRCP is expressed in the hypothalamus...
