While caloric consumption during binge eating has been measured, it is not
known how many of the calories are retained in the gastrointestinal tract
after vomiting. In 17 normal weight bulimic patients, there appeared to be
a ceiling on the number of calories retained after vomiting. That is,
whether or not bulimic patients had small (mean = 1,549 kcal, SD = 505) or
large (mean = 3,530 kcal, SD = 438) binges, they retained similar amounts
of kilocalories (mean = 1,128, SD = 497, versus mean = 1,209, SD = 574,
respectively) after vomiting.
