Furthermore, they said health and longevity improved with increased fasting time no matter what the mice ate or how many calories they consumed.
"This study showed that mice who ate one meal per day, and thus had the longest fasting period, seemed to have a longer lifespan and better outcomes for common age-related liver disease and metabolic disorders," coauthor Richard J. Hodes said in a statement. "These intriguing results in an animal model show that the interplay of total caloric intake and the length of feeding and fasting periods deserves a closer look."
While the researchers do not fully understand why fasting is associated with longevity, they hypothesize that “extended daily fasting period enables repair and maintenance mechanisms that would be absent in a continuous exposure to food.”
The analysts now hope to continue their investigations with other strains of mice to explore how time-restricted eating patterns might help humans to maintain their health.
