A comparison of a behavioral weight loss program to a stress management program: A pilot randomized controlled trial

Abstract Background Effective non-surgical long-term weight loss solutions remain elusive. Objective To compare a behavioral weight loss program (BWL) with a stress management-based program (Emotional Brain Training, EBT) on weight loss, blood pressure, depression, perceived stress, diet and physical activity. Participants/setting Individuals with a body mass index (BMI) of > 28 and < 45 kg/m2 were recruited in Lexington, Kentucky in January 2014 and randomized to a behavioral weight loss program (BWL) or a stress management program (EBT) for a 20 week intervention. Of those recruited, 49 participants were randomized to EBT or BWL. Randomization and allocation to group were performed using SAS software (v 9.3, 2011, SAS Institute Inc.). Weight, blood pressure, depression, perceived stress, dietary intake and physical activity were measured at baseline, 10, and 20 weeks. Main outcome measures Weight and Body Mass Index (BMI) Statistical analyses Linear models for change over time were fit to calculate 95% confidence intervals of intervention effects. Results BWL produced greater changes in BMI than EBT at both 10(p=0.02) and 20 weeks (p=0.03). At 10 weeks, both EBT and BWL improved BMI, systolic blood pressure, depression and perceived stress (p
