“Long-term population research has identified age-independent declines in testosterone in some male cohorts, supporting the view that changes in men's hormonal health can involve more than aging alone. BPA and phthalates can interact with hormone-related biological pathways.”

“One laboratory study found that disposable paper cups exposed to 85 to 90°C water released about 25,000 micron-sized particles into 100 milliliters within 15 minutes, along with many smaller particles. Tea bags can provide another source of exposure.”

“Time-restricted eating can help some people reduce eating opportunities, although a 12-month trial found no additional weight or body-fat benefit when an eight-hour eating window was added to calorie restriction. Sleep also affects appetite and fat distribution.”

“In a small study of 10 men, twice-weekly sauna sessions for three months altered sperm production and function, with recovery documented during follow-up after sauna use stopped. Sperm outcomes and circulating testosterone are distinct measures of reproductive function.”

“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.”

“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”

“A growing body of scientific evidence suggests that there is a correlation between decreased activation of the IGF-1 pathway and increased lifespan. Studies in worms and mice indicate that when the IGF-1 receptor is knocked out, the organisms remain disease-free and live longer.”

“Bruce argues that while diseases of severe vitamin D deficiency like rickets are rare, the criteria for vitamin D deficiency should be based on long-term health biomarkers and not just short-term severe diseases.”

“Eating late at night – particularly large meals – can be detrimental and, along with DNA damage, provides fertile ground for cancer to develop. In this clip, Dr. Ruth Patterson discusses how eating in accordance with the body's natural circadian rhythm may reduce the risk of breast cancer.”
