Intermittent fasting alters circadian gene expression in hepatocytes independently of caloric restriction

Scientists showed that the timing of meals — not just how much is eaten — reprograms metabolic gene activity in liver cells, providing a molecular explanation for why intermittent fasting may have health benefits separate from weight loss.
Abstract
Isocaloric comparison of time-restricted feeding versus continuous caloric intake in C57BL/6J mice demonstrated distinct patterns of CLOCK, BMAL1, and CRY1 expression in liver tissue, suggesting that meal timing drives metabolic reprogramming beyond caloric content.
