Thank you for your interest in our study! We are testing the combination of two new approaches to eating on cancer risk: time restricted eating and eating more dietary fiber. Each approach is only three months long.

What would I do?

If you take part in this study, you will come to the University of Oklahoma campus in OKC for an assessment three times in two years. At these visits, we will assess memory, weight, diet, blood, and surveys. You will also get a Fitbit and access to an app for data collection. You will also provide two stool samples, but you can do these from your home and mail them in.

Are there any risks or benefits?

Risks include discomfort from changing what you eat, risks that come from getting a blood draw, and sharing information about yourself. We will review these with you in detail. Benefits could include weight loss or other improvements in your health.

Will I get paid?

Participants in this study can get paid for completing data collection.
