How Fasting & Caloric Restriction Impact Health | Dr. Satchin Panda & Dr. Andrew Huberman
Huberman Lab Clips・2 minutes read
Researchers in Joe Takahashi's lab discovered that caloric restriction, particularly when food was distributed at specific times, led to longer lifespans in rats, with those fed during their active cycle living 20% longer. Biomarkers were unable to predict the longevity benefits of caloric restriction or time-restricted feeding, highlighting the complexity of the relationship between diet and lifespan.
Insights
- Caloric restriction, particularly when combined with time-restricted feeding during the active cycle, significantly extended the lifespan of mice in Joe Takahashi's experiment, showcasing the importance of meal timing in enhancing longevity.
- Contrary to expectations, biomarkers were unable to reliably forecast the longevity advantages of caloric restriction or time-restricted feeding, indicating that the mechanisms behind these benefits may be more complex and multifaceted than previously assumed.
