About this study

You are invited to participate in a research study being conducted by Karen Gibson, Maria Morgan-Bathke, Dana Swope, Grace Huebner, Rebecca Brannan, Samuel McCormick at Viterbo University. The purpose of this research is to determine the effectiveness of using nuts and avocados as a dietary intervention on improving fasting blood glucose, lipid profile, energy expenditure, and body composition on pre-diabetic individuals compared to a control group. We hope to learn if a dietary intervention of nuts or avocado can help improve blood sugar, lipid panel and/or body composition. You were selected as a possible participant in this study because you have been diagnosed with pre-diabetes. If you decide to participate, you will be asked to complete an initial two hour appointment, follow the protocol of one of the interventions (one avocado or 1 ½ ounce nuts) and control group with only dietary counseling provided) daily for an eight week period, weekly telephone and/or email nutrition counseling, and attend a final two hour appointment. The food for the intervention (avocados and nuts) will be provided by the researchers and will not need to be purchased by the participants. The initial and final two hour appointments will consist of the following measurements: An overnight fast, blood glucose, cytokine level, and lipid panel tests will be completed by a venous blood draw. Then Maltron scan (to measure body composition, which in non-invasive and uses electrodes on the skin), waist/hip measurements, height/weight, and VioCare food frequency questionnaire will be completed. Following these screening measurements, a COSMED test to determine resting energy expenditure (REE) will be measured.

It may take approximately 10 weeks from beginning to completion of this study.

Questions about this trial

What is this clinical trial studying?

A study testing Pecan Intervention in people with Obesity & Overweight, run by Viterbo University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

body composition (time frame: 10 weeks). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07732816.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2026.
