title: New evidence for a thermogenic defect in human obesity.
abstract: A reduced thermogenic response to food ingestion may contribute to the dynamic phase of weight gain in obesity. A defect in diet-induced thermogenesis has been reported in about one third of an unselected group of obese women. After inducing weight loss with a hypocaloric diet, the thermogenic defect does not disappear. Since basal metabolic rate decreases with weight loss, the overall postprandial energy expenditure of 'post-obese' individuals can be lower than that of lean controls. As a consequence, post-obese subjects must reset energy intake to a lower level than the previous maintenance food consumption in order to avoid relapse of body weight gain.
