Andrew Huberman・2 minutes read
Dr. David Sinclair discusses aging as a disease that can be slowed or reversed through interventions like diet, supplements, and behavioral changes, emphasizing public education on aging biology and practical tools. The 'lifespan podcast' launching on January 5th, 2022, aims to educate on aging biology, reversing aging, and providing actionable protocols for increasing lifespan, featuring discussions with Dr. Sinclair.
Insights
- Dr. David Sinclair, a genetics professor at Harvard Medical School, views aging as a disease that can be slowed or halted through intervention points identified in behavioral, nutritional, supplementation, and prescription drug methods.
- Aging is equated to the loss of information due to entropy, with genetic and epigenetic information playing crucial roles in longevity and health, emphasizing the importance of controlling gene expression for combating aging effects.
- Intermittent fasting, supplements like NMN and resveratrol, and exercise play pivotal roles in activating defense mechanisms for longevity, with personalized adjustments necessary based on individual responses and factors like microbiome composition and age.
- The potential for gene therapy to rejuvenate the body, starting with eye treatments to reverse age-related damage and blindness, showcases groundbreaking advancements in science that may have far-reaching implications for human health and longevity.
- Public health education efforts, advancements in biological age testing, and the democratization of health information aim to empower individuals to make informed decisions about their well-being, bridging the gap in understanding and offering personalized recommendations for improving overall health and lifespan.

Recent questions
How can aging be viewed according to Dr. Sinclair?
Dr. Sinclair views aging as a disease that can be slowed or halted, contrary to it being a natural consequence. He believes that aging can be combated through various methods such as behavioral changes, nutritional adjustments, supplementation, and prescription drugs. By identifying intervention points and addressing the underlying causes of aging, Dr. Sinclair aims to educate the public on aging biology and interventions to promote longevity and overall health.
What is the focus of Dr. Sinclair's 'lifespan podcast'?
The 'lifespan podcast' launched by Dr. Sinclair on January 5th, 2022, focuses on aging biology and intervention tools. The podcast aims to educate listeners on the mechanistic science behind aging, ways to reverse aging, and practical tools for daily life. Dr. Sinclair, along with his guests, discusses aging, longevity, and actionable protocols to increase lifespan, emphasizing aging as a disease that can be addressed by understanding its underlying mechanisms.
How can intermittent fasting impact longevity?
Intermittent fasting, particularly skipping a meal a day or longer fasting periods like 48 or 72 hours, can trigger autophagy, a process that cleanses the body of old and misfolded proteins. By activating sirtuins and down-regulating mTOR through fasting, the body's defense mechanisms for longevity can be triggered. Research suggests that periods of hunger, rather than actual hunger, activate defensive genes for longevity, making intermittent fasting a potential tool for promoting health and extending lifespan.
What are the benefits of NMN supplementation?
NMN supplementation impacts the sirtuin pathway and aging rates, serving as a precursor to NAD crucial for sirtuin activation and cellular functions. By taking NMN daily at a recommended dosage of one gram alongside resveratrol intake, individuals may experience improvements in insulin sensitivity and overall health. NMN supplementation, when consistent and monitored, can lead to increased NAD levels, potentially enhancing longevity and combating the effects of aging.
How can individuals monitor and improve their biological age?
Monitoring and measuring biological age is crucial to assess the effectiveness of lifestyle changes in promoting longevity and overall health. A biological age test, involving a simple mouth swab, is being developed to predict future health and lifespan. By taking the test and receiving personalized health scores and recommendations, individuals can make informed decisions about their well-being. The goal is to democratize the test, empowering individuals to understand their biological age and take steps to potentially reverse aging by making positive changes in their lifestyle.
