New research on circadian nutrition highlights the transformative potential of meal timing in alleviating fatigue. Nutrition Insight speaks to the study’s lead researcher, who underscores the role of circadian rhythm in muscle endurance and cognitive functions. The study in Science Bulletin reveals that time-restricted feeding, particularly night-restricted and day-restricted feeding, can enhance metabolic flexibility, restore muscle strength and reduce fatigue in rodent models. Time-restricted feeding creates an intermittent feed-fast cycle by restricting daily food intake to a particular window.
