How Do Fasting and Rapamycin Improve Longevity?

TL;DR

Fasting and rapamycin promote longevity by activating autophagy, reducing inflammation, and enhancing mitophagy, which removes damaged mitochondria. Both also suppress senescent cells that contribute to aging. Though rapamycin is used as an immune suppressant post-organ transplant, its potential for longevity remains largely underexplored in medicine.

Transcript

the only two things that seem to uniformly if done more or less correctly impose longevity are rapamycin and some degree of fasting so you then start looking at well what do those two things have in common well what they both have in common is they would certainly turn down mtor mechanistic Target of rapamycin and there are lots of other effects th...

Questions & Answers

Q: Why is rapamycin not commonly used in a pharmaceutical context?

Rapamycin is currently used as an immune suppressant in patients who have undergone organ transplants. Its potential longevity benefits have not been widely explored due to its side effects and the fact that it was initially approved for a different purpose.

Q: What is the connection between rapamycin and fasting?

Both rapamycin and fasting activate autophagy, reduce inflammation, promote mitophagy, and suppress senescent cells. These shared effects contribute to potential longevity benefits.

Q: How was rapamycin discovered?

Rapamycin was discovered in the 1970s during an expedition to Easter Island. A bacterium found in the soil produced a chemical that was later named rapamycin. It was initially explored as a treatment for athlete's foot before being repurposed as an immune suppressant.

Q: What research has been done on the longevity effects of rapamycin?

Studies in mice have shown that rapamycin administration can extend lifespan by around 9-13%. These results have been replicated in multiple species and have sparked further interest in rapamycin's potential for longevity benefits.
