我们提出了一个包含生理和心理因素的动态模型，该模型预测在减肥行为干预过程中身体质量和成分的变化。该模型由三个隔室的能量平衡和受计划行为理论启发的机械心理学模型组成。它描述了行为干预中的重要变量如何影响健康的饮食习惯和随着时间的推移增加的体力活动。该方法的创新之处在于将行为干预描述为一个动态系统，并整合了心理和能量平衡模型。给出了两个模拟场景，说明了该模型如何提高对干预成分的变化和参与者差异如何影响结果的理解。因此，该模型可以用来为行为科学家设计优化的减肥和身体成分变化干预措施提供信息。
We present a dynamical model incorporating both physiological and psychological factors that predict changes in body mass and composition during the course of a behavioural intervention for weight loss. The model consists of a three-compartment energy balance integrated with a mechanistic psychological model inspired by the Theory of Planned Behaviour. This describes how important variables in a behavioural intervention can influence healthy eating habits and increased physical activity over time. The novelty of the approach lies in representing the behavioural intervention as a dynamical system and the integration of the psychological and energy balance models. Two simulation scenarios are presented that illustrate how the model can improve the understanding of how changes in intervention components and participant differences affect outcomes. Consequently, the model can be used to inform behavioural scientists in the design of optimized interventions for weight loss and body composition change.
