Summary
Dr. Rhonda Patrick shares protocols for fasting, reducing dementia risk, and reversing heart aging. Discusses optimal sauna use for longevity (hotter is not always better) and supplements that actually matter. Covers cognitive aging reversal with common multivitamins.

- Supplementation becomes more important as we age
- Fasting protocols for healthspan extension
- Sauna for longevity—optimal protocols (hotter is not better)
- Strategies for lowering dementia risk
- How to reverse heart aging through lifestyle interventions
- Evidence-based supplements that actually matter
Key Moments
16:8 fasting explained: not eating for 16 hours triggers autophagy and metabolic flexibility
Patrick walks through time-restricted eating -- 16 hours fasting, 8 hours eating -- and how it promotes autophagy and metabolic adaptation. They discuss how the fasting window can shift (noon-8pm or 2-10pm) and that training at harder intensities during the eating window enables metabolic flexibility.
"You're talking about not eating food for a period of time. That period can be 16 hours, 24 hours, or longer -- in which case it would be a prolonged fast."
190F sauna for brain health: Patrick uses sauna to get lactate and prevent neurodegeneration
Patrick targets 190F for sauna use, motivated by preventing neurodegenerative disease. Hot tubs show comparable effects on blood pressure regulation. She also uses 20g of exogenous ketones before early morning talks for a caffeine-free brain boost.
"I take the 20 grams of exogenous ketones and it's like you get this brain boost, but without the caffeine. It's hard to explain."
