    Areas of high exposure of Dioxin in Vietnam found to have associated elevated salivary cortisol, cortisone, and DHEA.  Now, this can only be seen as an association, but they did find these elevations only in the "hot spots" and not in low exposure areas.

  • f greater than 10, it demonstrates there is a degree of leptin resistance contributing to an inability to lose weight
  • that it is difficult to lose weight with leptin resistance. High carbohydrate diets and in particular high-fructose corn syrup is shown to significantly increase leptin resistance and is a likely mechanism that high fructose corn syrup is associated with obesity

  • inactive thyroid hormone called thyroxine
  • it is problem inside the cell that the inactive T4 is not converted to T3 but rather to a mirror image of T3 called reverse T3. The reverse T3 has the opposite effect of T3, blocking the effects of T3 and lowering rather than increasing metabolism.
  • Studies are showing that stress and dieting (especially yo-yo dieting) can set this hormone into action as well as chronic illness such as diabetes, chronic fatigue syndrome and fibromyalgia.
  • As soon as the body senses a reduction in calories, the production of reverse T3 is stimulated to lower metabolism
  • With chronic dieting or stress, the body often stays in this "starvation mode" with elevated levels of reverse T3 and decreased levels of T3, which is a major reason for the regaining of lost weight with dieting as well being the mechanism behind stress induced weight gain (it is not due to increased cortisol).
