The Israeli parliament has passed a new law which prohibits clinically underweight models from appearing in advertisements and catwalks. Lawmakers believe the presence of super-skinny models in the media and fashion parades encourages eating disorders and promotes unrealistic and unhealthy body image goals. In this new legislation, a model of either sex must have a BMI (body mass index) of at least 18.5 in order to be able to work. Proof will also need to be shown that a doctor does not find that that person is underweight. Even healthy-weight models who appear underweight are no longer allowed to be shown. Any artificial enhancements of images to make the person look thinner must be clearly stated (on the image). Dr Rachel Adato-Levy, a gynecologist and lawyer, who is also a member of the Knesset (Israeli parliament) for Kadima, said yesterday before the Bill was approved and became an Act that the new legislation should help protect young people from unrealistic beauty goals.
Researchers at Georgetown University Medical Center have revealed how a mutation in a single gene is responsible for the inability of neurons to effectively pass along appetite suppressing signals from the body to the right place in the brain. What results is obesity caused by a voracious appetite. Their study, published March 18th on Nature Medicine 's website, suggests there might be a way to stimulate expression of that gene to treat obesity caused by uncontrolled eating. The research team specifically found that a mutation in the brain-derived neurotrophic factor (Bdnf) gene in mice does not allow brain neurons to effectively pass leptin and insulin chemical signals through the brain. In humans, these hormones, which are released in the body after a person eats, are designed to "tell" the body to stop eating.
Loss Of Appetite Deciphered In Brain Cell Circuit: Therapeutic Targets Also Discovered For Potential Treatments For Eating Disorders
The meal is pushed way, untouched. Loss of appetite can be a fleeting queasiness or continue to the point of emaciation. While it's felt in the gut, more is going on inside the head. New findings are emerging about brain and body messaging pathways that lead to loss of appetite, and the systems in place to avoid starvation. Scientists have reported in Nature about a brain circuit that mediates the loss of appetite in mice. The researchers also discovered potential therapeutic targets within the pathway. Their experimental results may be valuable for developing new treatments for a variety of eating disorders. These include unrelenting nausea, food aversions, and anorexia nervosa, a condition in which a person no longer wants to eat enough to maintain a normal weight. The senior author of the paper is Dr.
Researchers at Drexel University have found that a majority of women with bulimia nervosa reach their highest-ever body weight after developing their eating disorder, despite the fact that the development of the illness is characterized by significant weight loss. Their new study, published online last month in the International Journal of Eating Disorders, adds to a body of recent work that casts new light on the importance of weight history in understanding and treating bulimia. "Most patients lose a lot of weight as part of developing this disorder, and all dedicate significant effort, including the use of extreme behaviors, to prevent weight gain, " said Jena Shaw, a clinical psychology doctoral student in Drexel's College of Arts and Sciences who was lead author of the new study.
People who suffered a stroke continued to experience eating problems and more than half still risked malnutrition after three months, even though there had been a marked improvement in most of their physical functions. That is one of the key findings of a study in the March issue of the Journal of Advanced Nursing. Researchers from the Karolinska Institutet in Sweden studied 36 patients who had had a stroke, assessing them in hospital at a median of five days. They then assessed them again approximately three months after their stroke, when they were back in the community, with the majority living in their own homes. All had experienced eating difficulties, reduced alertness or swallowing problems after their stroke. Just over half of the patients were female (58%) and they ranged from 40 to 80-years-of-age with a median age of 74.
