Voluntary weight loss in obese patients consistently reduces negative emotions such as depression and anxiety in the short term. Dieting by persons of normal weight is associated with low self-esteem and depressive symptoms. Dieting is linked to the development and maintenance of eating disorders such as anorexia nervosa and bulimia nervosa, although the precise nature of this association is unclear. Dieting cannot be a sufficient causal condition and must combine with other still undetermined vulnerabilities to cause eating disorders. Identification of these risk factors must precede the development of effective programs to prevent eating disorders.
肥胖患者主动减肥在短期内能持续减轻抑郁和焦虑等负面情绪。正常体重者节食与自卑及抑郁症状相关。节食与神经性厌食症和神经性贪食症等饮食失调症的发生和维持有关，尽管这种关联的确切性质尚不清楚。节食并非充分的因果条件，必须与其他尚未明确的易患因素相结合才会导致饮食失调。在制定预防饮食失调症的有效方案之前，必须先识别这些风险因素。
