Title: The Effect of a Stepped-care Approach to Long-term Weight Loss
Brief Summary: The number of overweight and obese adults in the United States is increasing at a rapid rate. A "stepped-care" weight loss program, which at key times increases the frequency of contact between an individual trying to lose weight and the program staff, may be beneficial for achieving long-term weight loss. This study will compare a standard behavioral weight loss program with a "stepped-care" weight loss program in their abilities to help people who are overweight or obese to lose weight.
