Lifestyle, Exercise and Nutrition Study 2 (LEAN 2)

Lifestyle, Exercise and Nutrition (LEAN) Study 2

The specific aims of this study are to determine the efficacy and cost-effectiveness of a weight loss program compared with usual care (control) treatment on 6-month changes in body weight, body fat, serum hormones, and breast tissue markers associated with prognosis in breast cancer survivors.

We will conduct a two-armed study comparing a combination of an in-person and telephone weight loss program compared to usual care/wait list in 100 breast cancer survivors. Women will be randomized into one of the study arms using a random permuted block design. Research staff collecting body composition data, as well as reviewing forms and entering data, will be blinded to the participant's study group.
