Eating behavior in bulimia nervosa: multiple meal analyses.

Ten bulimic individuals were admitted to an inpatient unit and for 7 consecutive days eating behavior was observed and recorded. Age, sex, and weight-matched control subjects (n = 10) were admitted to the same unit for 4 d. All food and fluid intake, frequency of binge eating and purging, and ratings of appetite and mood before and after eating were recorded every 24 h. Bulimic patients demonstrated chaotic eating patterns that varied within as well as between individuals. Total daily energy intake was significantly higher for bulimic patients (41982 +/- 113 kJ; 10,034 +/- 2701 kcal) than for control subjects (8050 +/- 0427 kJ; 1924 +/- 102 kcal). On average, patients binged 1.6 times, purged three times, and ate one snack or meal without purging daily. Macronutrient analyses of intake revealed significantly less energy from protein and more energy from fat in bulimic patients compared with control subjects. Some improvement of mood was noted after binges, the magnitude of which was greatest after purging.

Eating pathology in bulimia nervosa.

Degree of eating pathology in bulimia nervosa was assessed using the Eating Behavior Rating Scale (EBRS) across three videotaped eating sessions. Twelve bulimic and 12 non-eating disordered subjects participated in this study. All subjects were filmed during a baseline meal (ad libitum), a high-calorie meal, and a low-calorie meal (both fixed amounts). Mean EBRS scores were significantly higher for bulimics (12.6 +/- 1.7) than for controls (3.9 +/- 0.9), suggesting a higher degree of eating pathology in these patients. Affect during eating was significantly more negative in the bulimic patients. EBRS and affect scores were significantly correlated [r (11) = .813, p < .01]. Bulimics had a slower rate of eating than controls and took significantly longer to initiate eating. Scores of pathological eating correlated with scores on the Eating Attitudes Test and the Bulimic Investigatory Test-Edinburgh, indicating a relationship between objective measures of pathological eating and self-report measures of eating disorder symptoms.

Decrease in resting metabolic rate during abstinence from bulimic behavior.

Among eight normal-weight bulimic women studied during 1 week of binge eating and vomiting and 7 weeks of abstinence without weight loss, resting metabolic rate and T3 and T4 levels fell significantly during abstinence. These data suggest that a physiological consequence of binge eating and vomiting is an increase in metabolic rate, in part due to increased thyroid hormone activity.
