The purpose of this study is to examine how walking may influence the bacteria living in the gut of people with prediabetes. Researchers from the University of Minnesota are recruiting adults in the Twin Cities metro area to participate in this study.

This research study is being conducted in the Twin Cities Metro Area Drs. Ryan Demmer and Mark Pereira at the University of Minnesota’s School of Public Health with funding from the National Institute of Diabetes and Digestive and Kidney Diseases at the National Institutes of Health.

You may be eligible if:

  • You have, or think you may have, pre-Diabetes
  • You are between the ages of 30 – 64 years
  • You have a BMI between 26-40.
  • You are not currently engaged in a regular exercise routine
  • You are able to speak and understand English

If you are determined to be eligible, you would be asked to:

  • Attend 4 study visits, varying in length from 15-25 minutes; 2 of these visits would involve fasting blood draws.
  • Complete 6 phone calls where you would be asked about what you ate the day before.
  • Wear a Fitbit for 11-weeks

For more detailed information on the visit schedule, see page 2 of the ActiveGUT Participant Fact Sheet (PDF).

If you are eligible and choose to take part in the study,

  • You can choose to either keep your Fitbit Inspire2 watch or choose to receive up to $80 for completing study activities.

You will be also provided with your personal study data, along with the overall study results at the end of the study.

If you have questions about the study, feel free to email us at or call/text 612-655-2133.

Sure! We’d love your help in recruiting eligible people.

Feel free to post the link to this website to your social media accounts (Facebook, Nextdoor, Twitter, etc), or post a flier (PDF) on a community posting board. People must be able to come to in-person visits in Minneapolis, MN.

This NIH-funded study was made possible through the work that we did in previous pilot studies. Pilot studies are small-scale, preliminary studies that are conducted in an effort to determine whether a full-scale project would work. They look to test things such as feasibility, participant burden, and scientific validity. Funding for pilot studies is often scarce which can lead to delays in getting great research projects off the ground. Philanthropic donations enable researchers at the University to make these small steps that can lead to large scale studies that can lead to dramatic impacts on the public’s health.

If funding more research related to the gut microbiome is important to you, consider making a tax deductible donation to show your support.
