Objectives: Poor adherence to diets and other weight-loss interventions is key to failure to achieve and maintain weight loss goals. In this study we evaluated the effects of a novel program incorporating cognitive-behavior therapy (CBT) and mindfulness-based stress reduction (MBSR) on weight loss and metabolic health.
Methods: In the 12-week CogniDiet® program, participants were taught to use CBT and MBSR techniques to help reframe thoughts and modify food-directed behaviors. No specific diet or calorie-counting regimen was imposed, although nutrition and exercise counseling were provided. Women ≥40 years of age who were chronic, unsuccessful dieters participated in this single-arm study. Primary outcomes were change from baseline at 12 weeks in body weight (BW), body fat mass (BFM), percent body fat (PBF), and waist-to-hip ratio (WHR). Blood lipoprotein analyses were also conducted. Paired t-tests were used to assess the change in study measures.
Results: Of the40 women enrolled in the study, 34 completed all assessments and comprised the per protocol population, here reported on. Participants were largely white (76.5%), college-educated or higher (70.6%), engaged in no or infrequent exercise (67.5%), and had a mean age of 55.7 years. Mean baseline BW, BFM, PBF, and WHR were 200.9 (±35.7) lbs, 83.8 (±20.9) lbs, 41.3 (±3.6)%, and .95 (±.05), respectively. At 12 weeks, we observed a significant decrease in mean BW, to 188.9 (±35.7) lbs (mean difference, 12 [±7.5] lbs, P P P
Conclusions: The results provide support for the efficacy of CBT and mindfulness training techniques, in tandem with nutrition and exercise counseling, in promoting weight loss and improving metabolic parameters. The 6-month results suggest durability of the observed effects. Further follow-up is planned.
