An Analysis of the Relationship between Binge Eating Disorder and Metabolic Disorders in Adults

The incidence of binge eating disorder (BED) has dramatically increased in recent years, leading to increased rates of psychiatric and medical comorbidities such as obesity and diabetes. Metabolic disorders are a series of metabolic dysfunctions, represented by central obesity, insulin resistance, and dyslipidaemia. This literature review aims to explore the relationship between BED and metabolic disorders in adults, helping to raise early awareness of these issues. PubMed was used as the exclusive database for its comprehensive and authoritative medical content. The review includes 13 peer-reviewed articles from the past decade, excluding studies on animals and children due to significant differences in BED characteristics across age groups and species. The focus remains on adult populations, as studies on gender or age effects showed no significant impact. Overall, BED has a strong relationship with metabolic disorders; people with BED will have higher risks for visceral obesity and Type 2 diabetes, whereas the limitations of research, such as further research on the complexity of BED, should be improved, and some people have opposite opinions, indicating a need for further in-depth investigation.
