The stress factor in obesity: cause or consequence?

14 February 2012

The World Health Organization (WHO) has described the consumption of food high in fat, salt and sugar, combined with  low physical activity as the main cause of obesity.

Doctors then prescribed weight loss and exercise. All of which are jumped up by the media and food industries that promote advice on training, diet and lifestyle.

 Brynjar Foss, a biologist at the University of Stavanger and Sindre M Dyrstad, a sports scientist, have reviewed a number of studies that show a link between weight gain and the level of cortisol (stress hormone). This publication suggests that stress and obesity can strength from each other. Weight gain can potentially trigger a stress response, which in all, promotes further weight gain. But dieting may also stimulate the production of cortisol, which in turn can trigger a stress response and thus counter the weight loss.

"Should our hypothesis turn out to be correct, it would mean that you’ld have to break this stress pattern if you wanted to stop the weight increase » says Foss.
