Proposed is a 6-month randomized controlled trial, in 200 overweight or obese Stage I-IIIC breast cancer survivors examining 6-month changes in: 1) body weight, 2) diet, 3) physical activity, and 4)quality of life in women randomized to receive the modified LEAN intervention compared to women randomized to wait-list control (i.e., the wait-list control will receive the modified LEAN intervention after completing the 6-month study).
The purpose of the study is to evaluate the effects of modifying the LEAN intervention (NCT02110641) to make it more cost effective by reducing or eliminating the counseling sessions. To guide the modification of the intervention one or more focus group sessions with former LEAN participants will be conducted. The purpose of these meetings will be to gain input on enhancing the LEAN book.
The LEAN book will be central to the modified intervention, but the LEAN book will be modified based on feedback from the focus group(s) and experience gained from the LEAN study. The reading level of the LEAN book will also be assessed to ensure acceptability to those with a low literacy level.
Once these changes have been finalized, the efficacy of the modified program will be tested using the methods described in the Brief Summary.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| LEAN | Experimental | Participants randomized to the weight loss program will initially receive the LEAN book, as well as a CD and flash drive with the LEAN videos (and internet link), a pedometer and the Log Book for recording their food intake and physical activity. Written instructions in the LEAN book will include recording daily diet and exercise in the logs. At the end of the study, participants will return, via a stamped addressed envelope, the logs to the study office so compliance can be assessed. |
|
| Waitlist Control | No Intervention | Participants randomized to the waitlist control study arm will be mailed the six-month questionnaires, which will include reporting of weight. On return of the 6-month questionnaires each woman will be provided with the entire weight loss program packet. |

| Body weight (kg) | A standard digital scale will be mailed to each participant along with the baseline packet to allow consistent measurement of weight by participants. Participants will weigh themselves. Body weight will be collected in kilograms (kg). | 6 Months |

| Quality of Life (QOL) | QOL will be self-reported and collected at the baseline and 6-months. The Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire will be administered to assess overall quality of life. The FACT-B measures physical, emotional, social, and functional well-being as well as quality of life issues specific to breast cancer survivors. The overall score will be used for assessment. | Baseline |

| Dietary Intake | The endpoint measures of diet change will be mean, group level changes in daily caloric intake, based on a 120-item food frequency questionnaire (FFQ) which was developed for the Women's Health Initiative Study and has been validated against 4-Day Food Records and 24-hour Dietary Recalls. The FFQ is used to generate the Healthy Eating Index score (HEI). The HEI will be used to assess dietary intake. | Baseline |

| Physical Activity (Moderate) | Women will complete a physical activity questionnaire to assess their past six months of physical activity.10 Hours/week spent in different types (recreational, household, and occupation) and intensities (light, moderate, and vigorous-intensity) of activity will be computed over the past six months. Total minutes per week will be calculated from this survey for moderate and vigorous activity. | Baseline |
