The idea of stress as the cause of the majority of modern abdominal obesity is really pretty silly IMHO. Unless, of course, you're willing to include obesity and inactivity as prime stressors! (which they certainly are).
The link between observed cortisol levels and abdominal obesity shows that obese people actually have IMPAIRED cortisol production in the liver (where it is normally produced at the highest levels). In a lean person this might lead to hypocortisolism. Fortunately for obese people, adipose tissue is also a great source of cortisol production, and their body more than compensates for the reduction in liver production by ramping up adipose production.
To put it bluntly, obesity causes elevated cortisol production and not the other way around in the vast majority of overweight people. I think that if they were not so fat, they would be less 'stressed' on many levels!
This does not mean that drugs which can reduce cortisol (prolly by inhibiting the enzyme in adipose tissue that converts cortisone to cortisol) are not beneficial to someone trying to lose fat. But there is no evidence that relacore does this, and it is erroneous to believe that the cortisol made you fat in the first place. Too much food makes you fat. Less food makes you lose fat.
And as spatts said, genuine stress that causes illness should be stopped at the source. A bandaid will not help long term.......
