Under calorie restriction, the rodents self-imposed chronic cycles of two-hour feeding and 22-hour fasting, raising the question of whether if it is calories, fasting or time of the day that is the cause of this increased life span.

“Our results show that circadian interventions promote longevity and provide a perspective to further explore mechanisms of ageing,” concluded the authors.

The study authors also suggested these effects could be replicated in humans if they ate all their meals within a 12-hour time frame.

The findings chime with previous research showing that reset of the circadian clock can lead to enhanced well-being and lifespan.
