Summary

The purpose of this study is to examine whether adding phone coaching to an Internet-based weight loss program can improve weight loss outcomes at 4 months and 1 year. All individuals will receive a 4-month, Internet-delivered weight loss program followed by an 8-month Internet-delivered weight loss maintenance program. Some individuals will also be selected to receive either 3 weeks or 12 weeks of phone coaching. Assessments of weight, diet, physical activity, and psychosocial factors will occur at baseline, 4 months, and 1 year.
