在冬眠季节、孵化、蜕皮和保卫领土或后宫期间，各种物种在食物存在或无法寻找食物的情况下吃得很少。在这些时候，喂养与其他更重要的活动竞争。避免进食和这些其他活动之间冲突的一种方法是降低体重或体脂设定值。对哺乳动物冬眠动物和孵化鸟类的实验提供了证据，证明设定点确实降低了。未能吃在这两个例子取决于厌食症，食欲不振。对其他例子的回顾表明，降低设定点的概念化为理解动物王国中许多自然发生的禁食提供了一种统一的、可检验的方式。最后，自发的动物肥胖症与人们减肥的尝试形成对比。
Eating very little in the presence of food or failure to search for food has been documented in various species during the hibernation season, incubation, molting, and defense of the territory or harem. At these times feeding competes with other, more important activities. One way to avoid conflicts between feeding and these other activities is to lower the programmed weight or set-point for body fat. Experiments on mammalian hibernators and incubating birds provide evidence that set-points are indeed lowered. Failure to eat in these two examples depends on anorexia, loss of appetite. A review of other examples suggests that conceptualization in terms of lowered set-points provides a unified and testable way of understanding many naturally occurring instances of fasting in the animal kingdom. Finally, spontaneous animal anorexias are contrasted with attempts by people to lose weight.
