摘要
To test the hypotheses that bariatric surgery-induced weight loss: induces remission of food addiction (FA), and normalizes other eating behaviors associated with FA.Forty-four obese subjects (BMI= 48 ± 8 kg/m(2) ) were studied before and after ∼20% weight loss induced by bariatric surgery (25 Roux-en-Y gastric bypass, 11 laparoscopic adjustable gastric banding, and eight sleeve gastrectomy). We assessed: FA (Yale Food Addiction Scale), food cravings (Food Craving Inventory), and restrictive, emotional and external eating behaviors (Dutch Eating Behavior Questionnaire).FA was identified in 32% of subjects before surgery. Compared with non-FA subjects, those with FA craved foods more frequently, and had higher scores for emotional and external eating behaviors (all P-values <0.01; all Cohen's d >0.8). Surgery-induced weight loss resulted in remission of FA in 93% of FA subjects; no new cases of FA developed after surgery. Surgery-induced weight loss decreased food cravings, and emotional and external eating behaviors in both groups (all P-values < 0.001; all Cohen's d ≥ 0.8). Restrictive eating behavior did not change in non-FA subjects but increased in FA subjects (P < 0.01; Cohen's d>1.1).Bariatric surgery-induced weight loss induces remission of FA and improves several eating behaviors that are associated with FA.
