What this trial studies

This pilot study investigates the feasibility of implementing a Fasting-Mimicking Diet (FMD) specifically tailored for Asian Americans diagnosed with prediabetes. Participants will follow a calorie-restricted nutrition regimen over a 5-day period, and the study aims to assess recruitment, adherence, and attrition rates, as well as the diet's effects on fasting blood glucose levels and physical measurements. Participants will undergo pre- and post-diet evaluations, including surveys and blood tests to measure glucose and ketone levels.

Why it matters

Potential benefit: If successful, this approach could provide an effective dietary intervention to help manage prediabetes in Asian American populations.

How similar studies have gone: While the Fasting-Mimicking Diet is a novel approach, similar dietary interventions have shown promise in managing metabolic conditions.
