Accepts healthy volunteers: no
Allocation: NA
Intervention model: SINGLE_GROUP
Intervention model description: To explore individual differences in responses to the weight loss intervention as well as mechanisms underlying its effects, additional survey measures will be administered. These measures will include: demographics, other health information, motivations for losing weight (TSR-Q), personality (BFI-10), chronic stress (Life Events Inventory) perceived stress (PSS-10), stress in past week, the positive and negative affect scale, PROMIS scale of cognitive function PROMIS scales of physical function, PROMIS scales of mental health, PROMIS scales of social health, fear of cancer recurrence, and self-efficacy for diet and exercise. PROMIS items will be assessed using computerized adaptive testing versions with items drawn from banks specific to the individual constructs assessed.
Primary purpose: TREATMENT

Brief summary: The purpose of this study is to test a new weight loss intervention designed for cancer survivors who have heart disease or cardiometabolic conditions. The investigators want to determine whether this study is feasible and acceptable to participants. The investigators also want to learn more about how cancer survivors take their medications.

Detailed description: 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.
