My Best GI Eating Study

Summary

The MyBestGI 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.
