The overall aim of the proposed study is to determine the effectiveness of a 3-month yoga program on increasing compliance and improving weight loss while participating in the Sanford Profile program. Participants are randomized to one of three groups: in-class yoga, yoga by digital video disk (DVD), stretching by DVD. Changes in weight loss and stress levels are monitored.
The overall aim of the proposed study is to determine the effectiveness of a 3-month yoga program on increasing compliance and improving weight loss while participating in the Sanford Profile program. The 6-month study includes a 3-month randomized, controlled trial using in-person yoga, a yoga DVD, and a stretching DVD (control group) followed by a 3-month post-intervention follow-up. The study will be conducted to test the hypotheses that both in-person yoga classes and DVD yoga participation will result in 1) greater compliance with the Profile program, 2) greater weight loss during the yoga intervention, and 3) greater weight loss 3 months following completion of the intervention compared to the stretching intervention. Compliance will be investigated using percent of days that dietary intake was entered online and percent of days that online records indicate that the program was followed. Changes in weight will be measured using data transmitted from electronic scales that are provided as part of the Profile program. In order to assess weight change after participation in the intervention we will ask participants to continue weighing themselves daily for 3 months following completion of the intervention regardless of whether they completed the Profile program or not. Participants will complete online questionnaires on behavioral and appetite perceptions related to eating, food intake, stress levels, compliance with diet recommendations given to them by Sanford Profile, and perceived benefits of their intervention. We will use these measures to determine the effect of yoga participation on eating behaviors and stress levels.

Weight loss
All participants are enrolled in a weight loss program. This outcome will tell us whether yoga increases weight loss during the intervention.
Time frame: 3 months
Weight loss
This outcome will tell us whether yoga participation results in long-term weight loss 3 months after the intervention stops.
Time frame: 6 months
Stress levels
Stress levels are measured using the Perceived Stress Scale (PSS). This outcome will tell us whether yoga participation reduces stress levels during intervention.
Time frame: 3 months
Stress levels
Stress levels are measured using the Perceived Stress Scale (PSS). This outcome will tell us whether yoga participation has a long-term (3 mo) effect on reducing stress after intervention stops.
Time frame: 6 months
