Description

Summary

The objective of this proposed study is to collect initial efficacy data on ROC and ROC + BWL compared to an active comparator (AC) and to BWL.

Official Title

Treatment of Obesity Targeting Appetite and Cue Reactivity

Details

The investigators have developed a new model for the treatment of obesity, called Regulation of Cues (ROC), which is based on Schachter's Externality Theory. The ROC program targets two theorized mechanisms for overeating in Schachter's Theory; decreased sensitivity to appetitive cues and increased sensitivity to external food cues. Considering that BWL has merit for some people, but fails to facilitate maintenance, this study will compare ROC, BWL, ROC+BWL combined and an active comparator (AC). The investigators will recruit overweight/obese adults and will assess them at baseline, mid-treatment (month 6), post-treatment (month 12), mid-follow-up (month 18) and follow-up (month 24). Assessments will include body mass index (BMI), body composition, and binge eating over the course of treatment and follow-up. This study will contribute to the study of basic behavioral mechanisms and food intake, could provide a novel model for the treatment of obesity, and could inform clinical decision making regarding obesity treatment.
