“In this member Q&A clip, Dr. Rhonda Patrick shares four practices she uses or finds compelling for healthy aging: sauna, sulforaphane-rich foods or supplements, time-restricted eating, and high-intensity interval training.”

“Translating sleep insights into practical steps These findings highlight the possibility of using heat therapy or vigorous exercise to influence slow-wave sleep, drawing on the interplay between body temperature regulation, immunity, physical activity, and hormones.”

“Earlier long-term research in older male physicians found no cognitive benefit, and the main COSMOS trial did not significantly reduce invasive cancer, cardiovascular events, or mortality over a median of 3.6 years.”

“Visceral fat can respond to changes in energy balance and physical activity. A meta-analysis of 40 randomized trials and 2,190 adults with overweight or obesity found that both exercise and calorie restriction reduced CT- or MRI-measured visceral fat.”

“A meta-analysis of seven randomized trials involving 182 participants found that high-intensity interval training improved flow-mediated dilation by 4.31%, compared with 2.15% after moderate-intensity continuous training, with a 2.26-percentage-point advantage between groups.”

“In this clip from Dr. Rhonda Patrick's appearance on Katie Couric's Next Question, she explains why magnesium supports both immediate energy needs and long-term cellular maintenance. Magnesium serves as a cofactor for more than 300 enzymes and helps maintain DNA structure, replication, and repair systems.”

“Mouse studies of feeding during infection also found different responses across bacterial and viral models, so a minimally processed dietary pattern, regular exercise, and normal hydration and nutrition during illness provide a more useful foundation than one universal food or fasting rule.”

“In an early randomized workplace study, healthy employees who completed an eight-week mindfulness program showed a greater rise in antibodies after influenza vaccination than a waitlist group.”

“Dr. Patrick's practical takeaway is to favor a well-formulated, non-aerosol mineral sunscreen, especially zinc oxide, while avoiding inhalation and recognizing that mineral and chemical filters have different evidence and uncertainties.”

“Whereas fasting turns off multiple pathways associated with aging, such as mTOR and IGF-1, eating for optimal fitness activates these important processes. The IGF-1 pathway, in particular, plays key roles in growth and is strongly associated with cancer.”
