Inpatient treatment has been found to cause significant reductions in BMI between 6 and 12 months after treatment. At 3 to 6 months following treatment, abstinence rates were 44% with a total weight loss of 5.6 to 6.3kg. However, this reductions in BMI and binge-eating lost significance past the 12-month mark. As such, while inpatient treatment is acutely effective in reducing body weight, it does not appear to promote lasting improvement among binge eating disorder patients.
