Rationale: The study investigates the association between body fat, eating behaviors, and physical activity before and after a Mediterranean diet.

Methods: 200 individuals with a high risk of metabolic disease underwent a 12-week intervention diet (ID) based on Mediterranean dietary principles1. The Three Factor Eating Questionnaire (TFEQ) and International Physical Activity Questionnaire (IPAQ) assessed eating behaviors and physical activity. Body fat was measured using bioelectrical impedance (BIA) (n=190) and dual-energy X-ray absorptiometry (DEXA) (n=140). Pearson correlations were calculated and presented as R2.

Results: Uncontrolled eating (UE) scores were correlated with waist circumference (0.03 before ID, 0.02 after ID), BIA fat mass (0.03 before ID, 0.02 after ID), and BIA fat percentage (0.06 before ID, 0.04 after ID). Similar correlations were found with DEXA fat mass (0.04 before ID, 0.04 after ID). DEXA fat percentage (0.07) and triglyceride levels (0.02) showed significant correlation with UE before ID, though this correlation was not observed following dietary intervention.

Emotional eating (EE) showed significant correlation with DEXA fat mass (0.11 before ID, 0.05 after ID) and DEXA fat percentage (0.12 before ID, 0.04 after ID). EE showed a significant correlation with BIA fat percentage only after ID (0.08). Cognitive restraint showed a significant correlation with DEXA fat mass and only after ID (0.03). Weight, visceral fat, non-esterified fatty acid, and physical activity showed no significant correlations with any eating behavior domains before or after ID.

Conclusion: Body fat may be related to uncontrolled eating in this cohort.
