Human alimentary behavior deals with a threefold need: energetic, hedonic and sociocultural. Among the clinical constellation offered by obese patients it could be worthwile to distinguish: 1. Some constitutional and organic obesities, pathogenesis of which does not imply an abnormality of alimentary behavior; 2. Conversely, in some other cases, psychological induced behavioral abnormalities are able to lead to an overstepping of the so called "normal" weight; 3. In other instances, the alimentary behavior reflects the elevation of the set point for weight. All these mechanisms are mutally reinforcing and could act simultaneously or successively accounting for the great variability of the individual situations. In any case environmental conditions are operating and play a pathogenic role more especially as the anatomic, physiologic and psychologic background is predisposed.
能量需求、享乐需求和社会文化需求。在肥胖患者呈现的临床症候群中，或许值得区分以下几种情况：1. 某些体质性和器质性肥胖，其发病机制并不意味着饮食行为异常；2. 相反，在其他一些情况下，心理诱发的行为异常能够导致超过所谓的“正常”体重；3. 在其他情形中，饮食行为反映了体重设定点的升高。所有这些机制相互强化，可能同时或相继起作用，这就解释了个体情况的巨大差异。无论如何，环境条件都在起作用，并且尤其在解剖学、生理学和心理学背景易患肥胖的情况下发挥致病作用。
