|Official Title:||Enhanced Behavioral Intervention to Improve Long-Term Weight Loss in Young Adults|

|Actual Study Completion Date :||November 2014|
|Active Comparator: Standard Behavioral Weight Loss Intervention||
Behavioral: Standard Behavioral Weight Loss Intervention
Subjects in this group will receive our standard behavioral weight control program that is delivered in an in-person group-based format. At month 7 subjects will also be given access to a study website to monitor eating and activity behaviors, and to have electronic access to standardized intervention materials. At month 7 subjects will also receive targeted study-related text messages that otherwise would have been provided in paper format.
|Experimental: Enhanced Weight Loss Intervention||
Behavioral: Enhanced Weight Loss Intervention
Subjects in this group will participate in a weight loss intervention that includes technology enhancements. These enhancements will include the addition of intervention specific targeted and tailored text messaging and the BodyMedia Fit System® beginning at Month 7. At month 7 subjects in EWLI will also receive the same targeted study-related text messages provided to SBWP that otherwise would have been provided in paper format.
- weight change [ Time Frame: Change from baseline to 24 months ]Body weight will be assessed on a digital scale to assess change in body weight over the 24 month intervention period.
- body composition [ Time Frame: 0, 6, 12, 18 24 months ]Body composition will be assessed using DXA. This will provide a measure of lean body mass, fat mass, bone mineral content, and percent body fat.
- cardiorespiratory fitness [ Time Frame: 0, 6, 12, 18, 24 months ]A graded exercise test on a treadmill along with indirect calorimetry will be used to measure cardiorespiratory fitness. This will provide a measure of oxygen consumption and metabolic equivalents of work at the time of test termination.
- physical activity energy expenditure [ Time Frame: 0, 6, 12, 18, 24 months ]A questionnaire and a portable device worn on the upper arm will be used to measure and quantify energy expenditure from physical activity.
- dietary intake [ Time Frame: 0, 6, 12, 18, 24 months ]A questionnaire will be used to assess self-reported food intake. This will be used to estimate calories, dietary fat, protein, and carbohydrates consumed.
- psychosocial and behavioral measures [ Time Frame: 0, 6, 12, 18, 24 months ]Questionnaires will be used to assess self-efficacy for weight loss and physical activity, barriers to physical activity and weight loss, expected outcomes resulting from physical activity and weight loss, perceived body image, depressive symptomotology, sleep patterns, weight history, dietary disinhibition and restraint, and behaviors typically related to weight loss (e.g., self-weighing, meal planning, etc.).
