Grazing and loss of control related to eating: two high-risk factors following bariatric surgery.
BACKGROUND  Gastric restrictive surgery  induces a marked change in eating behavior . However , the relationship between preoperative and postoperative eating behavior and weight loss outcome has received limited attention . OBJECTIVE This study assessed a range of eating behaviors before and 1 year after laparoscopic adjustable gastric b and ing ( LAGB )  and explored the nature and extent of change in eating patterns , their clinical associates , and impact on weight loss . METHODS AND PROCEDURES A 12-month observational study assessed presurgical and postsurgical binge eating disorder ( BED ) , uncontrolled eating , night eating syndrome ( NES ) , grazing , nutrient intake and eating-related behaviors , and markers of psychological distress .  A total of 129 subjects ( 26 male and 103 female , mean age 45.2 + /- 11.5 and BMI 44.3 + /- 6.8 ) participated in this study . RESULTS Presurgical BED , uncontrolled eating , and NES occurred in 14 % , 31 % , and 17.1 % of subjects , which reduced after surgery to 3.1 % , 22.5 % , and 7.8 % , respectively ( P = 0.05 for all ) . Grazing was prevalent before ( 26.3 % ) and after surgery ( 38.0 % ) . Preoperative BED most frequently became grazers ( P = 0.029 ) . The average percentage weight loss ( % WL ) was 20.8 + /- 8.5 % ; range -0.67 to 50.0 % and percentage of excess weight loss ( % EWL ) 50.0 + /- 20.7 % ; range -1.44 to 106.9 % ( P < 0.001 ) . Uncontrolled eating and grazing after surgery showed high overlap and were associated with poorer % WL ( P = 0.008 and P < 0.001 , respectively ) and elevated psychological distress . DISCUSSION Consistent with recent studies , uncontrolled eating and grazing were identified as two high-risk eating patterns after surgery . Clearer characterization of favorable and unfavorable postsurgical eating behaviors , reliable methods to assess their presence , and empirically tested postsurgical intervention strategies are required to optimize weight loss outcomes and facilitate psychological well-being in at-risk groups
