This study is being conducted to better understand how increasing dietary fiber intake may affect blood sugar levels and overall health in young adults with prediabetes. Researchers are also exploring whether a fully remote program that provides fiber-rich groceries, continuous glucose monitoring, and mobile health education is a practical way to support healthy lifestyle changes.

You may be eligible for this study if you meet the following criteria.

Inclusion Criteria:

• Ages 18–39
• Adults who are at risk for diabetes
• Not currently taking a GLP-1 medication

Overall Duration

This study lasts about 4 months total. The study includes two in-person visits and a remote program completed from home.

In-Person Activities

Participants will attend two in-person study visits, one before the program begins and one after it ends.

During these visits, participants will:

• Have their height and weight measured
• Provide blood samples through a blood draw
• Complete tests about how they perceive bodily sensations

At-Home Activities

The main part of the study is completed remotely over 3 months.

Participants will:

• Receive weekly deliveries of high-fiber groceries to their home
• Wear a continuous glucose monitor (CGM) to track blood sugar levels
• Use a smartphone app to receive nutrition and health education

Participants may receive up to $283 for completing study activities. Participants will also receive weekly deliveries of high-fiber groceries, a continuous glucose monitor (CGM) to track blood sugar levels during the study, and nutrition education through a smartphone app.
