Influence of short-term dietary weight loss on cortisol secretion and metabolism in obese men

Abstract

Weight loss with VLCD in obesity reverses up-regulation of hepatic A-ring reductases and normalises cortisol production rate; in contrast, starvation produces acute stress and further activation of cortisol secretion. We suggest that activation of cortisol secretion is not an irreversible intrinsic abnormality in obese patients, and speculate that dietary content has an important influence on the neuroendocrine response to weight loss.
