“00:20:21 - Some of the key blood-based biomarkers that are useful for tracking and projecting future cognitive health, including: homocysteine (<7μml/L preferred), which Dr. Bredesen indicates may be a mediator of cerebral atrophy, and also fasting insulin (<5% preferred), hemoglobin A1c, fasting glucose, vitamin D, and a number of other hormones relevant for trophic support.”

“Her practical message is to reduce the frequency and size of large glucose exposures. Foods with intact fiber, protein, and minimally processed carbohydrates digest more slowly than refined added sugar, while regular exercise gives skeletal muscle a large destination for circulating glucose.”

“In a two-year trial of 237 postmenopausal women, approximately 9 to 10 grams per day combined with resistance training and walking did not add a bone-density benefit, so its role is better framed around muscle and physical function.”

“In this excerpt from Dr. Rhonda Patrick's A4M LongevityFest 2023 keynote, she argues that vigorous exercise is one of the most powerful tools for healthy aging because it can raise cardiorespiratory fitness.”

“In 25,241 adults who reported no structured exercise, a median of three one- or two-minute vigorous lifestyle bouts per day was associated with 38% to 40% lower all-cause and cancer mortality and 48% to 49% lower cardiovascular mortality.”

“In a randomized crossover study of 18 men with overweight or obesity, breaking sitting with squatting or short walking bouts lowered post-meal glucose exposure more than one 30-minute walk, even when energy use and total activity time were matched.”

“Controlled human studies support acute brain-related responses to high-intensity exercise. Six short all-out cycling intervals improved selected learning and executive measures while increasing circulating BDNF, IGF-1, and VEGF; lactate tracked several of these changes.”

“Studies of centenarians suggest that lower levels of inflammation are associated with longevity. Different types of fiber provide fuel to diverse species of bacteria in the gut, which then synthesize byproducts that regulate the inflammatory process.”

“Dr. Patrick explains some of the early evidence that suggests the value prolonged fasting (48+ hours) may have from the standpoint of tissue rejuvenation and healthspan maintenance, as well as relevance for other more specific conditions.”

“In this clip, Dr. Valter Longo discusses the origin of the fasting-mimicking diet and a possible future which may lean away from a drug-centered mentality to one which allows the body to heal itself.”
