Weight loss medications like liraglutide show promise for reducing binge eating (BE) episodes in obesity. While individual studies suggest benefits, meta-analyses require more consistent data for definitive conclusions on BE reduction.
Area of Science:
- Pharmacology
- Clinical Medicine
- Psychiatry
Background:
- Obesity is a complex condition often associated with binge eating (BE) disorder.
- Effective pharmacologic interventions for weight management and comorbid BE are needed.
Purpose of the Study:
- To systematically evaluate the impact of approved weight loss medications on binge eating episodes in individuals with obesity.
Main Methods:
- Systematic search of randomized controlled trials and prospective interventional studies.
- Independent, duplicate data extraction and risk of bias assessment.
- Analysis of baseline characteristics, therapies, BE scales, and study duration.
Main Results:
- Eight trials (870 participants) analyzed; most participants were women (63%), mean age 45, BMI 35-40 kg/m².
- Liraglutide showed weight loss but not statistically significant BE reduction in meta-analysis.
- Naltrexone/bupropion reduced BE in individual studies; Orlistat had no significant effect.
Conclusions:
- Liraglutide effective for weight loss in obese patients with BE.
- Liraglutide and naltrexone/bupropion may improve BE severity, but meta-analysis was limited by heterogeneous assessment tools.
- Larger, prospective studies with longer follow-up are necessary to confirm findings.
