obesity

Can body weight, or weight-loss attempts for that matter, be affected by eating 3 meals daily as opposed to simply "grazing" on mini-meals throughout the day? New data from Australia suggests that for women, at least, grazers run a bigger risk of being overweight or obese.
Despite the public health warnings about obesity, since 1999 its prevalence has increased markedly. And the latest CDC stats show that the trend continued for both adults and youngsters between 2014 and 2016. But amid the otherwise depressing statistics, there is a glimmer of hope buried within.
Someone considering bariatric surgery, specifically the so-called Roux-en-Y procedure, will be glad to know that the benefits are long-lasting, according to a new study. Those who underwent it not only maintained much of their weight loss for at least 12 years, they also were less likely to develop type 2 diabetes than equally-obese people who didn't have that surgery.
There are two different types of fat: white and brown. White fat is a fat storage depot, whereas brown fat transforms energy into heat. Researchers have successfully created a patch containing a micro-needle that delivers sustained release drugs in nanoparticles, stimulating white fat to turn to brown.
Both obesity in general, and central obesity, are associated with a higher risk of some breast cancers, finds a new Chinese study. The strength of the association was affected by whether the tumors carried receptors for estrogen or progesterone.
Sleep deprivation has been associated with an increased risk of obesity in several studies. A new one, based on a large British survey, assessed whether that link could be due to over-eating by bleary-eyed people. But the data didn't support that hypothesis, so researchers will have to look harder to explain that link.
While bariatric surgery is the most effective means of dealing with extreme obesity, subjects must still exercise some degree of dietary discipline to obtain the most benefit. A new analysis finds that the degree of early weight loss predicts long-term success, and both are linked to decreases in energy intake.
It's well known that menopause incurs many negative consequences, including hot flashes, bone loss and added weight in the abdominal area (visceral fat — the worst kind). Any of these can have negative health effects, and current treatment options such as drugs to prevent/treat osteoporosis don't do anything for added fat, or vice versa. But recent research in mice suggests that blocking the hormone FSH could greatly help.
A new report supposedly gives credence to the idea that "endocrine disrupting chemicals" found in house dust can cause obesity. But the results weren't even found in animals, let alone humans.
America has about the highest proportion of overweight and obese on Earth, but the rest of the world is hot on our heels. A massive meta-analysis of global data indicates that between 1980 and 2015 the prevalence of obesity doubled in more than 70 countries.
An important question is what type of exercise — aerobic, such as walking, swimming or bike riding; or resistance, such as weight lifting — would help the older obese person who's looking to lose weight? The answer is both, particularly when done in tandem.
Many groups blame sugar and sugar-sweetened beverages for the epidemic of obesity. Some have argued that a tax on them would lower consumption, and thus decrease the prevalence of obesity. But a recent Australian study showed that decreasing intake of these drinks was actually accompanied by an increase in obesity prevalence.
