M-POWER Feasibility Study

The purpose of this study is to test a new weight loss intervention designed for cancer survivors. The investigators want to determine whether this approach to weight loss is feasible and acceptable to cancer survivors. All participants in the study will receive free behavioral telephone-based weight loss management in the Department of Preventive Medicine at Northwestern University. Participants must be willing and able to use their smartphone with Bluetooth and their WiFi to download Apps, set up a Fitbit account and a Google account if not already set up. Participants will use their smartphone to record food intake & physical activity over an 8 week weight loss program. This program includes recruitment of a "Buddy" that the participant will choose to support you during the 8 week study.

All participants will be asked to download a study application to use to record dietary intake each day during a "Run-In Week.". Eligible participants will then receive an 8-week weight loss program, including individual weekly sessions with health coaches. The investigators will also ask participants to complete both a baseline and follow-up session with study staff. If permitted by current university policies, these sessions will be held at the offices on Northwestern University's Chicago campus. Otherwise, these sessions will be conducted remotely via Zoom videoconference. If this is the case, as a privacy safeguard, the waiting room feature will be applied so that study staff can control who is admitted into the meeting. We expect that the participants will be in this research study for about 10 weeks.

The primary risk of participation is muscle soreness or injury from increased physical activity, as well as feelings of hunger from making changes to diet. The main benefit is that a participant may experience positive changes to their health and mood based on the study.
