Impact of eating behavior on 24‐month weight change after treatment of severe obesity—A clinical prospective cohort study
Main finding · Weight lossResult — go to the resultDifference in weight loss 3.5 kg 95% CI 0.02–6.9Authors' conclusion
The association between pretreatment eating behaviors and weight change was found to be generalizable and not restricted to any specific treatment. Certain eating behaviors may affect weight loss as well as attrition. Identifying eating behaviors that may impair treatment efficacy are suggested in the treatment of severe obesity.
