My Best GI Eating Study

Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

  • * Are within 12 months of bariatric surgery
  • * Pregnant or lactating women or women contemplating pregnancy for the duration of the protocol
  • * Taking anti-coagulants that interfere with ability to obtain a blood sample

  • * Have cancer at the present time
  • * Dietary intakes with substantial nutrient deficiencies that would require extensive counseling to correct, such as obtaining a large portion of calories from alcohol
  • * Unable to make their own daily food choices
  • * Showing evidence of lack of reliability or non-adherence to study procedures (for example, missing an eligibility screening or baseline enrollment appointment more than twice; unable to recall the previous day's diet)
  • * Reported dietary intakes reported that are not plausible or highly unusual as reported on the ASA24 (for example: \<500 or \>3500 kcal/day for women and \<800 or \>4200 kcal/day for men; or reporting too few foods eaten)
