Outcome Measures
Primary Outcomes (2)
Time spent in moderate-intensity physical activity
Participants will be given a closed motion sensor (Omron HJ-720 ITC Pocket Pedometers) to wear over the course of the program to measure number of steps and time spent engaged in moderate -intensity and higher physical activity. Days in which the sensor has been worn at least 10 hours only will be counted towards the seven days. The motion sensors will be downloaded onto computers at the baseline assessments and at week 9. During weeks 0 and 9 all participants will also keep a record of the self-reported physical activity.
Week 9
Television watching time
TV monitoring devices ("TV Allowances") will be hooked onto participants' home TVs by research staff. The devices will record the number of hours per week of TV the research participant is watching. Participants will also be asked to keep a record of their self-reported TV watching at 0 and 9 weeks.

Study Arms (2)
Physical Activity
ACTIVE COMPARATORA standard behavioral weight loss intervention with a physical activity prescription of 200 minutes of moderate intensity physical activity per week.
Physical Activity & TV Watching
EXPERIMENTALA standard behavioral weight loss intervention with a physical activity prescription of 200 minutes of moderate intensity physical activity per week and an additional prescription of reducing TV watching to 10 hours per week or less.
Interventions
All participants in the investigation will receive a standard 8-week behavioral obesity intervention with 8 weekly, 1 hour group counseling and education sessions. The intervention will include a reduced caloric prescription (1200-1500 kcal/day) and fat gram prescription (30% or less kcals from fat).
All participants will receive a physical activity goal of 200 minutes/week of moderate-intense physical activity.
The TV Watching + physical activity arm will receive a TV watching goal of watching less than 10 hours of TV/week.
