If you overeat once a week for three months, lacking self-control and experiencing over-fullness afterward, and are distressed, embarrassed, and disgusted with yourself, you are diagnosable. Apparently, people who feel bad about not being fully controlled in their eating when confronted by weekend buffet-style feasts are disordered.
（1）饮食失调：如果你在连续三个月内每周过量进食一次，进食时缺乏自我控制能力，进食过后感觉过饱，并有沮丧，尴尬和厌恶感，那么就可以诊断为饮食失调。很显然，那些在面对周末大餐而无法完全控制自己的人是机能失调的。
