ZEPEDA RUIZ, Wendy Andrea  e  VELAZQUEZ MARTINEZ, David N.. Effects of binge eating behavior upon the preference of rats for different corn oil solutions. Acta de investigación psicol [online]. 2018, vol.8, n.2, pp.114-125. ISSN 2007-4719.  https://doi.org/10.22201/fpsi.20074719e.2018.2.10.

Binge eating behavior is a food intake disorder characterized by an overconsumption of palatable food without an energy deficit. It has been reported the induction of binge eating with vegetable shortening, but also it has been reported that differences may exist on consumption depending upon the fat presentation (as vegetable shortening or corn oil). In addition, there is limited information on whether binge eating may modulate preference for options that differ on their caloric content. Therefore, main objectives were to determine whether is possible to induce binge eating using corn oil as the palatable food and whether preference for different oil concentrations is modified after binge induction. First, we determined the preference of the subjects to different oil concentrations; thereafter subjects were assigned to control (no binge induction) or experimental (binge eating induction protocol) on the basis of their oil consumption. Binge induction lasted one month and then a second two-bottle preference test was carried. Results showed that corn oil may be used as a palatable substance to induce binge eating behavior; also, it was observed an increase in preference for higher oil concentrations induced by binge, but preference was also modulated by deprivation conditions, suggesting normal regulation of caloric intake despite binge induction.
