Feasibility of Integration of Yoga in a Behavioral Weight-Loss Intervention: A Randomized Trial.

ABSTRACT

OBJECTIVE: This study examined the feasibility and comparison of two styles of yoga within the context of a standard behavioral weight-loss intervention (SBWI). METHODS: Fifty adults with obesity (BMI 31.3 ± 3.8 kg/m2 ) participated in this 6-month study that included a SBWI and a calorie- and fat-reduced diet. Randomization was to restorative Hatha (SBWI+RES) or Vinyasa (SBWI+VIN) yoga. Yoga was prescribed to increase from 20 to 40 to 60 minutes per session across the intervention. Weight was assessed at baseline and 6 months. Perceptions of yoga were assessed at the completion of the intervention. RESULTS: Adjusted weight loss was -3.4 kg (95% CI -6.4 to -0.5) in SBWI+RES and -3.8 kg (95% CI -6.8 to -0.9) in SBWI+VIN (P < 0.001), with no difference between groups. Of all participants, 74.4% reported that they would continue participation in yoga after the SBWI. Session duration was a barrier as yoga increased from 20 to 40 to 60 minutes per day, with 0%, 7.5%, and 48.8% reporting this barrier, respectively. CONCLUSIONS: Among adults with obesity, yoga participation, within the context of a SBWI, appears to be feasible, with weight loss not differing by style of yoga. Progressing to 60 minutes per session appears to be a barrier to engagement in yoga in this population.
