关于“节食”一词的用法有很大的差异。节食的常见定义包括可以说是适度的行为改变(例如，增加蔬菜消费)，被认为是更极端的行为改变(例如，禁食)，以及更模糊的行为(例如，减少碳水化合物)。更令人困惑的是，研究结果表明，许多支持节食的人实际上并没有减少卡路里的摄入量。因此，“节食”指的是从适度到极端的行为，试图在没有客观热量减少的情况下减少摄入量，在没有相关痛苦的情况下减少热量。不幸的是，现有的措施与这些差异很大的经验一起崩溃了。因此，饮食失调和肥胖领域在节食建议方面的协调性很差。一些人认为节食有助于饮食紊乱和肥胖的发展；另一些人则认为节食对于减少超重和健康风险是必要的。如果没有明确定义的节食结构，饮食障碍和肥胖领域都不能朝着有效的预测、预防或治疗取得进展。我们提出了一种新的分类方案，“心理行为节食范式”，它通过区分与不同节食体验相关的行为和心理维度，并对这些领域之间的相互作用进行分类，对现有的模型进行了改进。该模型旨在对支持节食的个人进行分类，独立于节食目标。目前，这个模型只是为了描述与不同结果相关的节食模式，而不是暗示这些模式与饮食紊乱和肥胖风险之间的因果关系。下面我们将描述这一范式，并提供研究方向。
There are significant discrepancies regarding use of the term “dieting.” Common definitions of dieting include behavior modifications arguably moderate (e.g., increasing vegetable consumption), those considered more extreme (e.g., fasting), and more ambiguous behaviors (e.g., reducing carbohydrates). Adding to confusion are findings demonstrating that many individuals endorsing dieting do not actually reduce caloric intake. Thus, “dieting” refers to behaviors ranging from moderate to extreme, attempts to reduce intake without objective caloric decrease, and caloric reductions without associated distress. Unfortunately, existing measures collapse together these widely discrepant experiences. As a result, there is poor coordination between the eating disorder and obesity fields in terms of dieting recommendations. Some suggest that dieting contributes to development of disordered eating and obesity; others argue that dieting is necessary for reducing excess weight and health risk. Without clearly defined dieting constructs, neither the eating disorders nor obesity fields can progress towards effective prediction, prevention, or treatment. We propose a novel classification scheme, the “Psycho-behavioral Dieting Paradigm”, which improves upon existing models by differentiating the behavioral and psychological dimensions associated with discrepant dieting experiences and categorizing the interactions between these domains. This model is intended to categorize individuals that endorse dieting, independent of dieting goals. At present, this model is only meant to describe dieting patterns associated with different outcomes, rather than to suggest causal relationships between these patterns and eating disorder and obesity risk. Below we describe this paradigm and provide directions for research.
