MyGI Diet for Colorectal Cancer Prevention
United States240 participantsStarted 2023-06-13
Plain-language summary
This study evaluates three different approaches that could help people eat in healthier ways. The study seeks to enroll 240 overweight and obese persons who have risk factors for colorectal cancers such as a family or personal history of colorectal cancers or adenomatous polyps. The study website is www.MyBestGI.org .
Participants in the study will be asked to follow one of three eating plans, as best they can, for 12 months. Study participants can choose the foods they prefer within healthy food groups. Two of the eating plans involve ten brief telephone support calls and use of a web-based app (MyBestGI App). The study primarily evaluates improvements in eating and any weight change that may result. Secondary goals for the research are to evaluate how changes in eating affect metabolic pathways.
All study participants will receive written materials that encourage making room for preventive foods in your daily eating. All participants also receive the results of their own diet analyses, and results of their own measures at study visits. The measures are the Veggie Meter skin reflectance test, Ketoscan breath test, and body composition measures. Study visits also involve providing a small blood sample from the arm. Study visits are in Ann Arbor at the start of the study, and at 6 and 12 months.
The long-term goal of this research is to provide better options for supporting individuals who seek to achieve and maintain a preventive style of eating.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
