Dial Now Study

Internet-based weight loss and weight loss maintenance program for 1 year with the possibility to receive phone coaching.

Study Type
Weight loss study
Study Purpose
The purpose of this study is to examine whether the addition of phone coaching to an Internet-based weight loss program improves weight loss.
Study Design

All individuals who are eligible and who enroll in this study will receive a 4-month, Internet-based behavioral weight loss program followed by an 8-month, Internet-based weight loss maintenance program. As part of this program, individuals are asked to view video lessons and log calorie intake, weight, and physical activity on the study website weekly. In addition to the Internet program, some individuals will also receive phone coaching. Individuals may be randomly assigned to either 3 weeks of phone coaching, 12 weeks of phone coaching, or no phone coaching. You cannot choose whether or not you receive the phone coaching, rather it is determined by a method similar to flipping a coin. It is estimated that approximately 50% of individuals will receive phone coaching.

In addition, we will also ask that you complete assessments at baseline, 4 months, and 12 months so we can evaluate various aspects of the program. These assessments are very important and include measures of weight, diet, physical activity, and several questionnaire measures.
