Obesity

Persistent exposure to light at night may lead to weight gain, even without changing physical activity or eating more food, according to new research in mice. Researchers found that mice exposed to a relatively dim light at night over eight weeks had a body mass gain that was about 50 percent more than other mice that lived in a standard light-dark cycle.

With the obesity rate rising for American adults and children, health concerns such as diabetes and cardiovascular disease are a frequent reality. Although obesity itself is a major risk factor for disease, most of the threat may be associated with a cluster of risk factors called the metabolic syndrome (MetS). Losing weight can improve health and reduce these risk factors, but many people have difficulty keeping the weight off.

Although obesity is a major risk factor for disease, much of the threat may be associated with the metabolic (or cardiometabolic) syndrome, a cluster of risk factors related to diabetes and heart disease. Losing weight can improve health and reduce many of these risk factors. However, many people struggle to keep the weight off long-term. Now, researchers at the University of Missouri have found that people who perform resistance training while regaining weight can help maintain strides in reducing their risks for chronic disease.

Although the whole population can benefit from a physically active lifestyle, in part through reduced obesity risk, a new study shows that individuals with a genetic predisposition to obesity can benefit even more.

The first study to demonstrate that obesity can directly accelerate the progression of acute lymphoblastic leukemia (ALL) has been conducted at The Saban Research Institute of Childrens Hospital Los Angeles and will be published in Cancer Prevention Research, on October 5, 2010.

Many people have experienced the frustration that comes with regaining weight that was lost from dieting. 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.

Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism.

An international study has discovered the reason why some people who eat a high-fat diet remain slim, yet others pile on the weight. The study, led in Australia by the Monash Obesity and Diabetes Institute (MODI) at Monash University, found a high-fat diet causes brain cells to become insulated from the body preventing vital signals, which tell the body to stop eating and to burn energy, from reaching the brain efficiently.

When a person is losing a significant amount of weight, they expect to notice changes in their body. However, they may overlook changes happening in their bones. During weight loss through calorie-restricted diets, bones are being remodeled - breaking down old bone and forming new bone - at an accelerated rate.

A higher-protein diet that emphasizes lean meats and low-fat dairy foods as sources of protein and calcium can mean weight loss without bone loss--and the evidence is in bone scans taken throughout a new University of Illinois study.

Researchers at McMaster University have developed a cocktail of ingredients that forestalls major aspects of the aging process. The findings are published in the...

A detailed study conducted by a team from the University of Athens on the Aegean island of Ikaria has demonstrated that moderate consumption of coffee by hypertensive elderly individuals can lead to improvements in aortic distensibility, according to a presentation at the European Society of Cardiology's Congress 2010 in Stockholm.
