Research regarding the definition and consequences of dieting has generated controversy for years. This controversy has spilled over into the public domain, especially as eating disorders and obesity have become more prevalent. One of the earliest and longest-lasting controversies involves the restrained eating framework, which was originally developed by Herman and Polivy and also strongly influenced the development of the cognitive-behavioral model of bulimia nervosa. An alternative framework for understanding the role of dieting in nonclinical and clinical groups, called the Three-Factor Model of Dieting, took a sharply different approach to defining, and understanding the impact of, dieting. This paper provides a brief historical review of the development of these divergent perspectives and updates the Three Factor Model's critical distinction between restraining eating to prevent over-consumption and dieting to lose weight. We suggest that three historical trends impacted the development of Restraint Theory in ways that unfairly impugned dieting for weight control: the emergence of the new eating disorders of bulimia nervosa and binge eating disorder, a population-based increase in loss of control eating and a population-based increase in obesity. This update is aimed in part at encouraging new research to reconcile ongoing, unresolved issues between Herman and Polivy's restrained eating model and the Three-Factor model of Dieting model. Such research might also contribute to the public's understanding of the pros and cons of dieting and to new approaches to treating eating disorders and obesity.

多年来，关于节食的定义和后果的研究引起了争议。这种争议已经蔓延到公共领域，特别是随着饮食失调和肥胖症变得更加普遍。最早和持续时间最长的争议之一涉及限制饮食框架，该框架最初由 Herman 和 Polivy 开发，也强烈影响了神经性贪食症的认知行为模型的发展。另一种理解节食在非临床和临床组中的作用的框架称为节食三因素模型，它采用了截然不同的方法来定义和理解节食的影响。本文对这些不同观点的发展进行了简要的历史回顾，并更新了三因素模型 节食以防止过度消费和节食以减轻体重之间的关键区别。我们认为，三个历史趋势以不公平地指责节食来控制体重的方式影响了克制理论的发展：神经性贪食症和暴食症等新饮食失调症的出现、基于人群的饮食失控增加和- 基于肥胖的增加。此更新的部分目的是鼓励新的研究，以协调 Herman 和 Polivy 的节食模型与节食模型的三因素模型之间正在进行的、未解决的问题。此类研究还可能有助于公众了解节食的利弊，并有助于开发治疗饮食失调和肥胖症的新方法。
