Identity Crisis of Satiety Neurons Leads to Obesity
Obesity -- as research in the past decade has shown -- is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular switch that controls the function of satiety neurons and therefore body weight. The findings were published in the journal Nature Metabolism. The worldwide … [Read more...]
How exercise reduces belly fat in humans
Some of you may have made a New Year's resolution to hit the gym to tackle that annoying belly fat. But have you ever wondered how physical activity produces this desired effect? A signaling molecule called interleukin-6 plays a critical role in this process, researchers report December 27 in the journal Cell Metabolism.

The center is a college-wide collaboration of researchers from … [Read more...]
Childhood obesity the major risk factor for serious hip disease
Slipped Capital Femoral Epiphysis (SCFE) is a disease that occurs amongst teenagers, affecting 1 in 2,000 children. The hip deforms, and sometimes completely collapses, causing pain and life-long disability. Early recognition and treatment of the disease is important to minimise the severity. Nevertheless, SCFE is one of the most common reasons for a hip replacement in young … [Read more...]
Among body shapes, pears are healthier than apples
For women, it usually accumulates around the hips, resulting in a pear-shaped look. In men, fat tends to build up around the abdomen, creating an apple shape.

Why zero-calorie sweeteners can still lead to diabetes, obesity
Increased awareness of the health consequences of eating too much sugar has fueled a dramatic uptick in the consumption of zero-calorie artificial sweeteners in recent decades. However, new research finds sugar replacements can also cause health changes that are linked with diabetes and obesity, suggesting that switching from regular to diet soda may be a case of 'out of the … [Read more...]
Combating childhood obesity by preventing ‘fatty liver’ in fetus
New research published in The Journal of Physiologyindicates that an obese pregnant mother and exposure to a high fat, high sugar diet during pregnancy produces a "fatty liver" in the fetus, potentially predisposing children to obesity, metabolic and cardiovascular disorders later in life. The research aims to understand the cellular mechanisms involved in laying down fat in … [Read more...]

Green tea ingredient may ameliorate memory impairment, brain insulin resistance, and obesity
A study published online in The FASEB Journal, involving mice, suggests that EGCG (epigallocatechin-3-gallate), the most abundant catechin and biologically active component in green tea, could alleviate high-fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment. Previous research pointed to the potential of EGCG to treat a variety of human diseases, … [Read more...]
Redefining obesity in postmenopausal women
There is no doubt the prevalence of obesity has increased significantly across all age groups, creating greater health risks. What exactly constitutes obesity, however, is subject to debate, especially for postmenopausal women who have a different body composition than younger women. A study published online today in Menopause, the journal of The North American Menopause … [Read more...]

The novel experimental and computational workflow involves the first use of rodent … [Read more...]
Abdominal fat a key cancer driver for postmenopausal women
Body fat distribution in the trunk is more important than body weight when it comes to cancer risk in postmenopausal women, according to a study presented at the ESMO 2017 Congress in Madrid. The findings put a new spin on weight management priorities for women in this this age-group, who are prone to abdominal weight gain, said study investigator Line Mærsk Staunstrup, … [Read more...]
Gene therapy via skin could treat many diseases, even obesity

Young adult obesity: A neglected, yet essential focus to reverse the obesity epidemic
The overall burden of the U.S. obesity epidemic continues to require new thinking. Prevention of obesity in young adults, while largely ignored as a target for prevention and study, will be critical to reversing the epidemic, says William Dietz, MD, PhD, Chair of the Sumner M. Redstone Global Center for Prevention and Wellness at the Milken Institute School of Public Health at … [Read more...]
Can smelling your food make you fat?
Our sense of smell is key to the enjoyment of food, so it may be no surprise that in experiments at the University of California, Berkeley, obese mice who lost their sense of smell also lost weight. What's weird, however, is that these slimmed-down but smell-deficient mice ate the same amount of fatty food as mice that retained their sense of smell and ballooned to twice … [Read more...]
Newly found, ‘thrifty’ genetic variant influences Samoan Obesity
The Samoas' world-leading rate of obesity is a recent phenomenon, heavily influenced by the globe's rapid shift to calorie-rich, processed foods and more sedentary lifestyles. A new study, however, suggests nearly half of Samoans have a newly identified and significant genetic variant that contributes to obesity risk; a variant that had remained undiscovered until … [Read more...]
