Feasibility and Preliminary Effects of Fasting-Mimicking Diet in Asian Americans With Prediabetes

This is a pilot study to determine the feasibility of studying the Fasting-Mimicking Diet (FMD), a dietary approach that involves the consumption of a specifically formulated, calorie-restricted nutrition regimen with a customized macronutrient composition, ratio, and quantity over a 5- day period, on a larger scale in Asian Americans with prediabetes and to examine the preliminary effects of the diet in study participants. The main questions the study aims to answer are: 1. What are the recruitment, adherence, and attrition rates of eligible participants into the study? 2. Does one FMD cycle result in changes in fasting blood glucose levels and physical measurements in study participants? Participants will be asked to undergo one cycle of FMD (for 5 days), fill out surveys, and come in for a pre-FMD and post-FMD study visit, during which physical measurements and fasting blood glucose and ketone levels will be measured.
