Many children are obese these days, but what can be done about it? Research-proven treatments for obesity exist, but they rely on regular one-on-one meetings with a trained health coach. So these "behavioral" treatments are seldom available outside of research studies in specialty medical centers. It's feasible and acceptable to give this same kind of behavioral treatment to … [Read more...]

An imbalance of female sex hormones among men in Western nations may be contributing to high levels of male obesity, according to new research from the University of Adelaide.

A new study from Uppsala University demonstrates that elderly humans carrying a common variant of the fat mass and obesity gene FTO also have a shifted endocrine balance. Low blood concentrations of the satiety hormone leptin and high blood concentrations of the hunger promoting hormone ghrelin makes carriers of the FTO gene put on weight. The findings are published in the … [Read more...]

Excess abdominal fat can be a precursor to diseases such as cardiovascular disease, type 2 diabetes and cancer. A person's measure of belly fat is reflected in the ratio of waist circumference to hip circumference, and it is estimated that genetics account for about 30-60 percent of waist-to-hip ratio (WHR). Kira Taylor, Ph.D., M.S., assistant professor, University of … [Read more...]

Fast food restaurants take a lot of heat for the rise in obesity in the United States, but is it really their fault?

Eating a diet rich in whole grains, polyunsaturated fats and nuts -- and low in red and processed meat, refined grains and sugary drinks -- is associated with a lower risk of chronic lung disease (chronic obstructive pulmonary disease or COPD), finds a study published in The BMJ this week. The finding supports the importance of a healthy diet to promote lung health. COPD … [Read more...]

Freiburg researchers demonstrate that LSD1 plays a key role in metabolic processes The human body reacts to environmental influences like cold or nutritional imbalance through adaptation. There is a change in metabolic processes in white adipose tissue in mammals. This results in the development of brown-like or beige fat cells, which are located in white fat depots and … [Read more...]

The transition from adolescence to adulthood presents individuals with many challenges. Perhaps none are as important as those relating to health and quality of life. Young adults, aged 18 to 25, are at high risk for weight gain. Being mild to moderately overweight during this period substantially increases the likelihood of obesity at age 35 to 37. To prevent weight gain and … [Read more...]

A new study from the University of Copenhagen's OPUS Research Centre reports that being overweight makes children less active. The findings underscore that parents of overweight children have an obligation to keep their children active, as physical activity is vital for the general health of all children. The study also shows that slender children do not become overweight due … [Read more...]

Eating breakfast causes obese people to be more active, according to the latest research published from researchers at the University of Bath (UK). The study, from health scientists based within the University's Department for Health and published in the leading diet and nutrition journal the American Journal of Clinical Nutrition, analysed the links between breakfast and … [Read more...]

In the fight against teenage obesity, some researchers have proposed targeting popular teens, in the belief that such kids would have an outsize influence on their peers. But in a Loyola University Chicago study, researchers were surprised to find that this strategy would be only marginally more effective than targeting overweight kids at random. Results are published in … [Read more...]

A new prescription weight-loss medication that combines a popular antidepressant with a medication for addiction will be reviewed by the Federal Drug Administration (FDA) for potential approval.

For years, scientists have failed to locate the DNA variants that control the weight-regulating hormone, leptin. However, new research has enabled the identification of four genes associated with leptin levels, which is particularly relevant within an obesity context. The study focuses on the powerful hormone leptin, which regulates humans' long-term energy balance by informing … [Read more...]

A new study led by Boston University School of Medicine (BUSM) demonstrates that the abnormal metabolism linked to obesity could be regulated in part by the interaction of two metabolic regulators, called the NAD-dependent deacetylase SIRT1 and fibroblast growth factor 21 (FGF21). Using experimental models, the researchers found that a lack of SIRT1 protein in the liver led to … [Read more...]

The calorie-burning triggered by cold temperatures can be achieved biochemically -- without the chill -- raising hopes for a weight-loss strategy focused on the immune system rather than the brain, according to a new study by UC San Francisco researchers. The team determined that two signaling molecules secreted by cells of the immune system trigger the conversion of … [Read more...]

Taxing sugar – before it’s added to processed foods – would reduce obesity-related disease in America, and cut medical costs to boot, according to research at Cornell and Stanford universities. “Nutrient-specific taxes could have an important effect in inducing healthier purchasing behavior among consumers,” Cornell’s Michael Lovenheim and Stanford’s Matthew Harding write in … [Read more...]

Weight loss surgery might have more value than simply helping morbidly obese people to shed unhealthy extra pounds.
