Graze Eating and Obesity: A Conceptualization Within the Spectrum of Disordered Eating

Area of Science:

• Behavioral Science
• Clinical Psychology
• Public Health

Background:

• Grazing is a distinct problematic eating behavior.
• It encompasses compulsive grazing (CG) and non-compulsive grazing (NCG).
• Understanding grazing is crucial for managing obesity and related health issues.

Purpose of the Study:

• To review recent literature on grazing behaviors.
• To examine compulsive (CG) and non-compulsive grazing (NCG) using consistent definitions.
• To assess the psychometric properties of instruments used to measure grazing.

Main Methods:

• Literature review of recent studies on grazing.
• Analysis of studies using consistent definitions and validated instruments.
• Synthesis of findings on prevalence, associations, and outcomes.

Main Results:

• Grazing is prevalent across diverse demographics and linked to socioeconomic status and cultural factors.
• Higher body mass index, poor weight loss, and metabolic control are associated with grazing, especially post-bariatric surgery.
• Compulsive grazing (CG) strongly correlates with psychological distress, eating disorder psychopathology, impulsivity, and reduced quality of life.

Conclusions:

• Grazing is a significant problematic eating behavior within the spectrum of disordered eating.
• It is associated with loss of control eating and negative health consequences.
• Assessing and addressing grazing behaviors is vital for obesity mitigation and improving associated medical risks.
