Inclusion Criteria:
18 to 70 years old with overweight/obesity (BMI of 25-45 kg/m2) who were willing to use electronic resources for weight loss if assigned to SMART.
Exclusion Criteria:
Currently in another weight loss program; taking weight loss medication; weight loss of >/=5% of body weight during the past 6 months; currently pregnant, lactating, less than 6 months postpartum, or plans to become pregnant during the next 18 months; report of a heart condition, chest pain during periods of activity or rest, or loss of consciousness on the Physical Activity Readiness Questionnaire (15); report of a medical condition that would affect the safety of participating in unsupervised PA; inability to walk two blocks without stopping; history of bariatric surgery; or report of conditions that in the opinion of the investigators would render the participant potentially unlikely to follow the protocol, including terminal illness, plans to relocate, a history of substance abuse, bulimia nervosa, or other significant uncontrolled or untreated psychiatric problem.
Research Purpose:
To test whether a primarily smartphone-based behavioral obesity treatment with electronic self-monitoring and feedback, as well as monthly clinic weigh-ins, would produce mean weight losses at 18 months that were at least as good as the more intensive gold standard treatment delivered via group sessions with paper diaries for self-monitoring and feedback.
