Scientists pinpoint protein link to fat storage
September 18, 2009
A protein found present in all cells in the body could help scientists better understand how we store fat. Researchers at the University of Edinburgh have found that the protein invadolysin, which is essential for healthy cell division, is present in lipid droplets - the parts of cells used to store fat.
The study also found that lower levels of invadolysin were linked to reduced amounts of fat deposits.
The findings, published in the Journal of Cell Science, could ultimately help scientists to better understand obesity-related complications, which can include diabetes, blood clotting and heart disease.
Professor Margarete Heck, at the University's Centre for Cardiovascular Science, said: "The presence of this protein in lipid droplets may suggest that it has a role in obesity. What we would like to understand is whether its presence is related to obesity, and if so, whether the protein's activity aggravates obesity and its consequences. Understanding its role will help us to better understand how the body stores fat."
Invadolysin was first identified by Professor Heck's laboratory in fruit flies. The latest study looked at the protein in human cells, pinpointing its presence in the part of cells used to store fat.
The researchers also found that when invadolysin was absent in fruit fly larvae, fat storage was impaired.
Further studies will look at how the protein affects metabolism to better understand its role in obesity-related disorders.

Fat Politics: The Real Story behind America's Obesity Epidemic
by J. Eric Oliver (Author)
It seems almost daily we read newspaper articles and watch news reports exposing the growing epidemic of obesity in America. Our government tells us we are experiencing a major health crisis, with sixty percent of Americans classified as overweight, and one in four as obese. But how valid are these claims? In Fat Politics, J. Eric Oliver shows how a handful of doctors, government bureaucrats, and health researchers, with financial backing from the drug and weight-loss industries, have campaigned to create standards that mislead the public. They mislabel more than sixty million Americans as "overweight," inflate the health risks of being fat, and promote the idea that obesity is a killer disease. In reviewing the scientific evidence, Oliver shows there is little proof that obesity...

The Obesity Epidemic: Science, Morality and Ideology
by Michael Gard (Author)
The Obesity Epidemic adds a much-needed voice of skepticism to the increasingly alarmist debate about weight and health. Gard and Wright show that "obesity" is above all a deeply problematic cultural and political concept, making clear that the social meaning of fat is determined largely by moral and ideological agendas -- agendas that are all the more powerful because they cloak themselves in the mantle of objective science and public health. Indeed, this book demonstrates how and why concepts such as "science" and "health" are themselves far more problematic than those who invoke them like to admit. THE OBESITY EPIDEMIC is a superb contribution to the sociology of knowledge, and an essential text for anyone who wants to understand the current moral panic over fat.

Killer at Large
Starring: Bill Clinton, Arnold Schwarzenegger, Michael Pollan, Mike Huckabee, Tom Harkin Directed By: Steven Greenstreet
Obesity rates in the United States have skyrocketed over the last twenty years, with no end in sight provoking former Surgeon General, Richard Carmona to state that "obesity is a terror within. It is destroying our society from within and unless we do something about it, the magnitude of the dilemma will dwarf 9/11 or any other terrorist event that you can point out..."
As this epidemic of obesity reaches out into even the most remote corners of the globe, only one thing seems clear, the issue is more complex than you could ever imagine.
Seeking to trace the problem to it's root, we find ourselves in the African Savannah 4 million years ago where we discover how our hunter gatherer ancestry, when mixed in with our modern environment of convenience, stress and abundance has...

The Evolution of Obesity
by Michael L. Power (Author), Jay Schulkin (Author)
In this sweeping exploration of the relatively recent obesity epidemic, Michael L. Power and Jay Schulkin probe evolutionary biology, history, physiology, and medical science to uncover the causes of our growing girth. The unexpected answer? Our own evolutionary success. For most of the past few million years, our evolutionary ancestors' survival depended on being able to consume as much as possible when food was available and to store the excess energy for periods when it was scarce. In the developed world today, high-calorie foods are readily obtainable, yet the propensity to store fat is part of our species' heritage, leaving an increasing number of the world's people vulnerable to obesity. In an environment of abundant food, we are anatomically, physiologically,...

Cognitive-Behavioral Treatment of Obesity: A Clinician's Guide
by Zafra Cooper DPhil DipPsych (Author), Dr. Christopher G. Fairburn DM FMedSci FRCPsych (Author), Deborah M. Hawker PhD DClinPsy (Author)
The first cognitive-behavioral treatment manual for obesity, this volume presents an innovative therapeutic model currently being evaluated in controlled research at Oxford University. From leading clinical researchers, the approach is specifically designed to overcome a major weakness of existing therapies: posttreatment weight regain. The book details powerful ways to help patients not only to achieve weight loss, but also to modify the problematic cognitions that undermine long-term weight control. Drawing on strategies proven effective with such problems as binge eating, the manual contains everything needed to implement the treatment: intervention guidelines, case examples, and reproducible handouts and forms.
