这项研究旨在确定当暴饮暴食前一天的能量摄入量没有减少时，限制进食方案是否会诱导暴饮暴食。将大鼠分为四组;在整个4周研究中，所有组均连续获得食物和水。此外，如下提供了对可选缩短的访问：（1）控制（1）：不访问缩短，（2）常规缩短访问-7（RSA 7）：每天2小时访问，（3）常规缩短访问-3（RSA 3）：每周一、周三和周五2小时访问，（4）非常规缩短访问（伊萨）：不同日期的2小时访问，因此缩短访问（狂欢）会话的数量与RSA 3相同，但最后一次。三届会议每届会议间隔4天。在最后两次暴饮暴食之前的几天，RSA 3消耗的能量显著低于任何其他组（p < 0.05），但伊萨摄入量等于对照组和RSAT的摄入量。在最后两次暴饮暴食期间，RSA 3和伊萨的摄入量没有差异，并且两组消耗的能量显著高于RSA 7或对照组（p < 0.05）。这些结果表明，暴饮暴食型饮食可以通过限制获得可选的脂肪食物来诱导，并且不依赖于前一天的饮食不足。(C)2003爱思唯尔有限公司。保留所有权利。
This study was designed to determine if a limited access feeding protocol would induce binge-type eating when energy intake on the day before the binge was not reduced. Rats were assigned to four groups; all groups had continuous access to chow and water throughout the 4 wk study. In addition, access to optional shortening was provided as follows: (1) Control (1): no access to shortening, (2) Regular Shortening Access-7 (RSA7): 2-h access everyday, (3) Regular Shortening Access-3 (RSA3): 2-h access every Monday, Wednesday, and Friday, (4) Irregular Shortening Access (ISA): 2-h access on various days, such that the number of shortening access (binge) sessions equaled that of RSA3, but the last. three sessions were each separated by 4 days. On the days prior to the last two binge sessions, RSA3 consumed significantly less energy than any other group (p < 0.05), but ISA intakes equaled those of Control and RSAT During the last two binge sessions, intakes of RSA3 and ISA did not differ, and both groups consumed significantly more than RSA7 or Control (p < 0.05). These results demonstrate that binge-type eating can be induced by limiting access to an optional fatty food, and does not depend upon undereating on the previous day. (C) 2003 Elsevier Ltd.
