09:33 🔥 Adversity mimetics like gene mutations and intermittent fasting can activate longevity defenses and combat aging, while modern comfort and abundance have made our defenses lethargic.
- Adversity mimetics, such as gene mutations and supplements, can activate the body's defenses and control aging, as demonstrated by Cynthia Kenyon's discovery of the DAF-2 gene in worms.
- Single gene alterations can have a significant impact on an organism's lifespan, as they work on a similar circuit that starts with adversity and activates a program for survival and stress resistance.
- Genes have various sensors that control cell activity, including mTOR, AMPK, and sirtuin, while insulin acts as a signaling protein to communicate with other cells, and mutated insulin signaling can mimic the benefits of hunger without starvation.
- Constant stressors in the environment have led to the evolution of longevity defenses, but modern society's comfort and abundance of food and shelter have caused these defenses to become lethargic, so we need to trick the body into getting out of its comfort zone by eating the right foods and less often.
- Intermittent fasting with adequate nutrition allows the body to turn on defenses without suffering long-term negative consequences, tricking the body into thinking food is scarce and activating mechanisms to burn fat, increase metabolism, and defend against insults.
