"Grazing": a high-risk behavior

Area of Science:

• Bariatric Surgery
• Eating Disorders
• Obesity Medicine

Background:

• Pre-existing disordered eating patterns in gastric bypass patients pose a risk for postoperative relapse.
• Binge eating is prevalent in obese individuals pre-surgery and post-surgery, linked to poorer outcomes.
• "Grazing" is identified as another high-risk eating pattern requiring investigation.

Purpose of the Study:

• To describe and investigate postoperative eating patterns in gastric bypass patients.
• To identify high-risk eating patterns, including binge eating and "grazing."
• To understand the transition of eating behaviors after bariatric surgery.

Main Methods:

• Patients completed pre-surgery self-report questionnaires and underwent mental health evaluations focusing on eating patterns.
• High-risk patients (binge eaters, "grazers") were identified for further study.
• Postoperative eating patterns were assessed via follow-up questionnaires and therapy group attendance.

Main Results:

• Many high-risk patients reported recurrent loss of eating control and some experienced weight regain.
• "Grazing" emerged as a common postoperative eating pattern, observed 6 months or more after surgery.
• Patients could no longer consume large quantities but continued to "graze."

Conclusions:

• Assessment of overeating in gastric bypass patients should focus on subjective loss of control, not just quantity.
• "Grazers," even without meeting strict binge eating disorder criteria pre-surgery, represent a high-risk group.
• Interventions are crucial for at-risk patients, as former binge eaters may transition to "grazing" post-surgery.
