Test meal intake in obese binge eaters in relation to impulsivity and compulsivity

Abstract

There was greater impulsivity in BED and BE, compared with non-BED. Moreover, impulsivity was the best predictor of TMI, and may play a larger role in BE than previously realized.

The validity and clinical utility of binge eating disorder

“…These authors speculated on the potential disinhibitory mechanism that may be stimulated by an instruction to binge eat. Consistent with this idea, Galanti et al 24 report that test meal intake for binge eating ranges widely, and is highly correlated with impulsivity.…”

“…16,17 Using a variety of different paradigms, the fundamental finding that individuals diagnosed with BED consume more calories than individuals without BED was supported in a number of early reports [18][19][20] and again in more recent studies. [22][23][24] Only rarely have researchers failed to find a BED versus obese non-BED difference in caloric consumption in a laboratory paradigm.…”

“…Supporting Information Table S2 provides a summary of a variety of laboratory-based studies [16][17][18][19][20][21][22][23][24] examining the eating behavior of individuals with significant levels of binge eating, commonly meeting diagnostic criteria for BED. Early studies of this type indicated that individuals with BED consumed more calories than weight-matched individuals without BED in several different stimulus conditions in the lab (e.g., instructions for binge eating, instructions for non-binge meal consumption).…”

Stress‐induced laboratory eating behavior in obese women with binge eating disorder

“…3 Laboratory studies show that obese patients with BED consumed significantly more calories than obese patients without BED in particular, when they were asked to simulate a binge. [5][6][7] However, it remains unclear from these studies, which characteristics of the eating style (microstructure of eating) contribute to the excessive caloric intake. There is evidence for a disturbance in satiety regulation in women with BED.…”

Appetite-Related Gut Peptides in Obesity and Binge Eating Disorder

“…15 The lifetime prevalence of other psychiatric diagnoses in those with BED is 60% to 72% as compared with 28% to 49% in controls. 39 Obese BED participants scored higher than matched non-BED obese controls on depression, anger, disinhibited eating, 40 impulsivity, 41,42 and overall psychopathology 43 and scored lower on self-esteem. 44 They had more frequent weight fluctuations and more shape-/weight-related concerns.…”
