Brief Summary

Recent research suggests that overweight persons who are physically active may be significantly less likely to develop health complications and less likely to die early when compared even with lean persons who are not physically active. Previous treatment programs for people who have struggled with their weight have focused almost entirely on weight loss as the main goal of treatment. Our research program has a different focus. We hope to improve health and healthy self esteem independent of body weight by focusing instead on increasing physical activity as the main goal of treatment. This is a small study designed to see if this approach would be appealing to persons who are struggling with their weight who are currently sedentary. It is designed for people who are otherwise fairly healthy for whom exercise is reasonably safe. Participants are randomly (by chance) assigned to participate in the experimental treatment program or instead to meet with their regular primary care doctor. Those who are assigned to meet with their regular doctor can access traditional weight loss resources such as Weight Watchers, Jenny Craig, Fitness centers etc... After the experiment is complete, these participants will have the opportunity to participate in the experimental treatment program.
