How Night Eating Syndrome Is Linked to Body Weight

Eleven studies have examined the association between night eating syndrome (NES) and body mass index (BMI).

• Five studies indicated a positive relationship between NES and BMI, while five others found no relationship.
• One study produced mixed findings regarding the association.
• Emotional eating and age may influence the relationship between NES and BMI.
• Twelve studies assessed BMI differences between individuals with and without NES, with only five reporting significant differences.
• The majority of the recent literature is cross-sectional, limiting insights into causality.
