Prediabetes is a metabolic condition associated with increased risk of type 2 diabetes and cardiovascular disease. Intermittent fasting (IF) has emerged as a potential dietary intervention to improve metabolic health, yet comparative evidence among different IF patterns remains limited.
This randomized controlled trial aims to evaluate the effects of three intermittent fasting regimens-5:2 fasting, alternate-day fasting, and time-restricted feeding-compared with a control diet on metabolic parameters, inflammatory markers, body composition, and nutrigenomic profiles in adults with prediabetes.
