Study: Fasting Affects Peripheral Circadian Clocks, Improves Overall Health

Kinouchi et al reveal that fasting affects peripheral circadian clocks in the liver and skeletal muscle. Fasting operates by influencing the circadian clock and fasting-sensitive transcription factors, thereby cooperatively achieving fasting-specific temporal gene regulation.
