Obesity

The benefits of blueberry consumption have been demonstrated in several nutrition studies, more specifically the cardio-protective benefits derived from their high polyphenol content. Blueberries have shown potential to have a positive effect on everything from aging to metabolic syndrome. Recently, a researcher from Texas Woman's University (TWU) in Denton, TX, examined whether blueberries could play a role in reducing one of the world's greatest health challenges: obesity.

"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 Université de Montréal Faculty of Medicine who has studied the leptin protein extensively.

If you are looking to lose weight in the coming year, you may need help from an unexpected place: the bacteria in your gut. That's because scientists have discovered that the bacteria living in your intestines may play a far more significant role in weight loss and gastrointestinal problems than ever imagined.

In a joint study, scientists from The Scripps Research Institute and the Dana-Farber Cancer Institute at Harvard University have uncovered a novel mechanism that dramatically increases insulin sensitivity and reduces the risk of developing type 2 diabetes and cardiovascular disease.

If you're happy and you know it, thank your friends—and their friends. And while you're at it, their friends' friends. But if you're sad, hold the blame. Researchers from Harvard Medical School and the University of California, San Diego have found that "happiness" is not the result solely of a cloistered journey filled with individually tailored self-help techniques.

In a study conducted among 25 healthy individuals living in a controlled setting who were randomized to overconsumption of different levels of protein diets, those consuming the low-protein diet had less weight gain compared to those consuming normal and high protein diets, and calories alone, and not protein appeared to contribute to an increase in body fat, according to a study in the January 4 issue of JAMA.

Researchers have found what appears to be a critical tuning dial for controlling whole body energy, according to a new report in the January issue of Cell Metabolism, a Cell Press publication. When energy levels within cells drop, it sets off a series of events designed to increase the amount of calorie-rich dietary fat that the body will absorb.

People who restrict their caloric intake in an effort to live longer have hearts that function more like those in people who are 20 years younger. Researchers at Washington University School of Medicine in St. Louis have found that a key measure of the heart's ability to adapt to physical activity, stress, sleep and other factors that influence the rate at which the heart pumps blood, doesn't decline nearly as rapidly in people who have significantly restricted their caloric intake for an average of seven years.

Growing older and being overweight are not necessarily associated with a decrease in mental well-being, according to a cross-cultural study looking at quality of life and health status in the US and the UK.The study, led by Warwick Medical School at the University of Warwick, analysed lifestyle and health patterns in more than 10,000 people in both countries and their links to participants' mental and physical quality of life and health status.

Obesity is a growing problem worldwide, but proper protein consumption can help keep it at bay, according to a paper published Oct. 12 in the online journal PLoS ONE. Researchers found that, when subjects were fed a 10% protein diet, they consumed 12% more energy over four days than they did on a 15% protein diet. Moreover, 70%...

New research from Uppsala University shows that a specific brain region that contributes to a person's appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep. Poor sleep habits can therefore affect people's risk of becoming overweight in the long run.

Activating a specialized type of fat, known as brown adipose tissue, may help combat obesity as well as result in better glucose control for type 2 diabetes, according to new research conducted by scientists at the UC Metabolic Diseases Institute.
