Sociocultural theory of ED
Cultural views of body image promote eating disorder behaviours because individuals are trying to achieve what society values
Pressure from media, peers, and family cause people to internalize the thin ideal causing someone to engage in eating disorder behaviours
Affect and emotional regulation of ED
Dual-pathway model of BN: affect regulation model: pressure to be thin and thin ideal internalization leads to body dissatisfaction which leads to dieting or negative affect and causes person to engage in behaviours to cope with mood
Weight suppression
difference between highest previous weight and current weight
As this number increases risk for eating disorder increases
Weight sUppression reduces leptin (which tells us whether we’re hungry or full, appetite hormone produced by fat)
This increases reward sensitivity and decreases reward satisfaction increasing likelihood of binge eating
Treatment of ED
Inpatient or partial hospitalization: for medical stabilization for AN weight restoration
Psychotropic medications: SSRIs are effective for BN and BED in combination with psychotherapy
No approved meds for AN - preliminary efficacy for Zyprexa/Olanzapineis front line treatment for BN but
CBT is used to treat BN but only world for about 50%
2 phases of breaking disordered eating habits
Phase 1: break binge purge cycle
Monitor eating habits

Avoid situations leading to binging
Develop better ways of coping with stress
Phase 2:
