This is how belly fat could increase your cancer risk
A new Michigan State University study now offers new details showing that a certain protein released from fat in the body can cause a non-cancerous cell to turn into a cancerous one. The federally funded research also found that a lower layer of abdominal fat, when compared to fat just under the skin, is the more likely culprit, releasing even more of this protein and encouraging tumor growth.

Is childhood obesity a psychological disorder?
A team of researchers, including senior investigator, Bradley Peterson, MD, director of the Institute for the Developing Mind at Children's Hospital Los Angeles, used fMRI to investigate neural responses to food cues in overweight compared with lean adolescents. (2017-08-22)

Brain's self-regulation in teens at risk for obesity
In a small study that scanned the brains of teenagers while exposing them to tempting 'food cues,' researchers report that reduced activity in the brain's 'self-regulation' system may be an important early predictor of adult obesity. (2017-08-22)

Energy dense foods may increase cancer risk regardless of obesity status
While there is a proven link between obesity and certain types of cancer, less is known about how the ratio of energy to food weight, otherwise known as dietary energy density (DED), contributes to cancer risk. To find out, researchers looked at DED in the diets of post-menopausal women and discovered that consuming high DED foods was tied to a 10 percent increase in obesity-related cancer among normal weight women. (2017-08-17)

Recently discovered brain chemical 'NPGL' controls appetite and body fat composition
NPGL, a recently discovered protein involved in brain signalling, has been found to increase fat storage by the body -- even when on a low-calorie diet. In addition, NPGL was shown to increase appetite in response to high caloric food intake, suggesting that perhaps we shouldn't feel so guilty about gorging on junk food from time to time. (2017-08-17)

Fat rats show why breast cancer may be more aggressive in patients with obesity
In an animal model of obesity and breast cancer, tumor cells in obese animals but not lean animals had especially sensitive androgen receptors, allowing these cells to magnify growth signals from the hormone testosterone. (2017-08-07)

Those behaviors, especially increased soda consumption, are important predictors of weight gain. (2017-07-31)

Dulled taste may prompt more calories on path to obesity
Cornell University food scientists have found that people with a diminished ability to taste food choose sweeter -- and likely higher-calorie -- fare. This could put people on the path to gaining weight. (2017-07-28)

Hunger-controlling brain cells may offer path for new obesity drugs
Scientists identified two new populations of cells in the brain that potently regulate appetite. The two types of cells, located in a part of the brainstem called the dorsal raphe nucleus, are potential targets for new drugs to treat obesity by controlling the hunger signals that drive the search for and consumption of food. (2017-07-28)

AAP counsels pediatricians to focus on clusters of cardiometabolic risk factors to help obese kids
Since frameworks used to identify adults at heightened risk for such complications are a poor fit for kids, the American Academy of Pediatrics now recommends that pediatricians instead focus on clusters of cardiometabolic risk factors that are associated with obesity. (2017-07-24)

Study finds obese patients don't need to lose weight before total joint replacement
There's good news from UMass Medical School for overweight people with painfully arthritic hips and knees: A new study finds that obese patients who underwent knee or hip replacement surgery reported virtually the same pain relief and improved function as normal-weight joint replacement patients six months after surgery. (2017-07-19)

Benefits of gastric bypass surgery linked to changes in sweet taste preference
Worldwide, the number of patients struggling with obesity is rapidly increasing in both adults and children.

While bariatric surgery can produce sustained and significant weight loss for most patients, not all patients experience similar benefits. (2017-07-18)

Estrogen in the brain prevents obesity and glucose intolerance during menopause in lab animal study
Researchers at the University of Cincinnati (UC) have found that adding estrogen in the brain may improve health in obese females after menopause. The study conducted by Christina Estrada, a doctoral candidate in the UC psychology graduate program in the laboratory of Matia Solomon, PhD, an Associate Professor in the UC Department of Psychiatry and Behavioral Neuroscience, used surgically-induced menopause to cause obesity in rats and identified brain areas that benefit from estrogen replacement. (2017-07-18)

Obese and overweight less likely to consider next meal when making portion size decisions
University of Bristol researchers have found that people with obesity tend to ignore how long it will be until the next meal when choosing how much to eat. In a study designed see if people consider the time interval between two meals when selecting portion sizes, the researchers found that lean people generally do (2017-07-18)

Weight gain from early to middle adulthood linked to increased risk of major chronic diseases, death
Weight gain from early adulthood (age 18 or 21 years) to age 55 was associated with an increased risk of major chronic diseases, such as type 2 diabetes, hypertension, cardiovascular disease, and death, and a decreased odds of healthy aging, according to a study published by JAMA. (2017-07-18)

Study links maternal obesity during pregnancy to behavioral problems in boys
Maternal obesity and child neurodevelopmental problems have both increased in the US and scientists have suggested a possible link. A new study has found that the heavier mothers were when they entered pregnancy, the higher the risk of behavior problems for their sons. However, it did not show the same effects in girls. The results are reported in the American Journal of Preventive Medicine. (2017-07-13)

Babies born big more likely to become obese as children, study finds

USPSTF recommendation regarding behavioral counseling for cardiovascular disease prevention
The US Preventive Services Task Force recommends that primary care professionals individualize the decision to offer or refer adults without obesity who do not have high blood pressure, abnormal cholesterol or blood sugar levels or diabetes to behavioral counseling to promote a healthful diet and physical activity. Existing evidence indicates a positive but small benefit of behavioral counseling for the prevention of cardiovascular disease in this population. The report appears in the July 11 issue of JAMA. (2017-07-11)

Stanford researchers find intriguing clues about obesity by counting steps via smartphones
A global study based on daily steps counted by smartphones discovers 'activity inequality.' It's similar to income inequality, except that the 'step-poor' are prone to obesity while the 'step-rich' tend toward fitness and health. (2017-07-10)

Muscles can 'ask' for the energy they need
Muscles require energy to perform all of the movements that we do in a day, and now, for the first time, researchers at the Texas A&M College of Medicine have shown how muscles 'request' more energy from fat storage tissues in fruit fly models. They also discovered that this circuit is dependent on circadian rhythms, which could have implications for obesity in humans. Their findings published today in the journal Current Biology. (2017-07-03)

Type 2 inflammation might be good for the belly but bad for the liver
An inflammatory response once thought to protect against obesity could exacerbate non-alcoholic fatty liver disease (NAFLD), which is why new findings suggest some targeted treatments for metabolic syndrome might need to be reevaluated. NAFLD is the most common type of progressive liver disease in developed countries and the second leading indication for liver transplantation. What's more, direct medical costs associated with NAFLD total as much. (2017-06-28)
