Article: A low-protein diet blocks development of hyperphagia and obesity in rats with hypothalamic knife cuts

ABSTRACT The objective of this study was to examine the influence of dietary protein levels on development of hyperphagia and obesity in rats that had been given surgical knife cuts between the ventromedial and lateral areas of the hypothalamus. Under normal conditions, rats with this type of surgery exhibit hyperphagia and become obese when given unlimited access to dietary energy. Earlier studies indicated impaired adaptive diet-induced thermogenesis in response to excess energy intake in this animal model of obesity. Because low protein diets can also stimulate diet-induced thermogenesis, we conducted four experiments which examined how diets containing different levels of protein affect ...
