Weight-loss maintenance is widely accepted to be a difficult and often elusive process. The transtheoretical model (TTM) provides a useful description of five stages of change. Applied to weight management, weight loss occurs during the action stage and weight-loss maintenance occurs during the maintenance stage. Despite its broad utility, the TTM does not adequately explain the complexity involved with a shift from action to maintenance. Based on Engel's (G. L. Engel, 1977, The need for a new medical model: A challenge for biomedicine, Science, Vol. 196, pp. 129-136) biopsychosocial model and family systems theory, a shifting processes model is proposed to describe the potential differences and shift that occurs between weight loss and weight-loss maintenance processes within relational contexts.
人们普遍认为，维持体重减轻是一个困难且常常难以实现的过程。跨理论模型（TTM）对五个改变阶段进行了有益的描述。应用于体重管理时，体重减轻发生在行动阶段，而体重维持则发生在维持阶段。尽管跨理论模型具有广泛的实用性，但它并未充分解释从行动阶段转变到维持阶段所涉及的复杂性。基于恩格尔（G.L.恩格尔，1977年，《对新医学模式的需求：生物医学面临的挑战》，《科学》，第196卷，第129 - 136页）的生物心理社会模型和家庭系统理论，提出了一个转变过程模型，以描述在关系背景下体重减轻和体重维持过程之间发生的潜在差异和转变。
