Fruit Fly Hormone – An Important Discovery In Battle Against Obesity

By Rob Poulos On October 12, 2012 No Comments

The discovery of an important metabolic hormone, thought only to be present in vertebrates, has been discovered in the fruit fly, according to researchers who’s findings were recently published in Cell. This hormone, known as leptin, is considered a nutrient sensor and regulates the intake and output of energy and is the primary controlling factor of the appetite. Because of this, it’s of great interest to those conducting obesity and diabetes research, from a molecular standpoint.

Before this discovery, only more complicated mammals and their use of this all-important hormone had been studied, primarily mice. But with the new results from this discovery, now fruit flies can be studied to find more insight into molecular beginnings of fat. According to one of the authors of the paper revealing these new discoveries, Akhila Rajan, the leptin hormone is a very complex entity. As they evolve, they develop more complex functionality.

October Report: Immune System Protein And The Fight Against Obesity

By Rob Poulos On October 11, 2012 No Comments

According to a report published in Immunity, researchers at Trinity College in Dublin, Ireland have found a new kind of anti-tumor immune cell that can help fight obesity and the metabolic syndrome that causes diabetes. The report, written by Marie Curie Fellow and Lydia Lynch from Trinity College, along with experts from Beth Israel Deaconess Medical Centre and St Vincent’s University Hospital, states that invariant natural killer T-cells (iNKT), immune cells that fight malignancy, disappear when humans become overweight, but can be restored once the weight is lost.

Their study showed that treatments that jump-start iNKT cells can help keep weight off and control diabetes and other metabolic diseases. The study concluded that iNKT cells, which were previously thought to be found infrequently in humans, are found in great numbers in the omental fat in humans. The study is further proof that immune system protein can help in the fight against obesity.

Recent Study: How Exercise Can Help Overweight Teens

By Rob Poulos On October 10, 2012 No Comments

While obesity is an issue that affects people of all ages, with more and more adolescents dealing with being moderately to seriously overweight, the effects are a bit more pronounced.

Obesity is associated with a litany of health issues, ranging from diabetes to chronic fatigue and hearth complications, overweight adolescents are also at an increased risk of body dissatisfaction, social alienation and low self esteem. As awkward as the teenage years can be for those who fall within the average weight range, studies have shown that those who are even slightly overweight can deal with additional mental and physical issues.

Dr. Gary Goldfield, a registered psychologist, clinical researcher at the Children’s Hospital of Eastern Ontario (CHEO) Research Institute, and Associate Professor in the Department of Pediatrics, University of Ottawa, recently set out to study how the effects of exercise may help improve the self esteem and overall body image of overweight teens
