“Dr. Patrick describes increased shear as a possible way vigorous exercise can damage fragile circulating tumor cells; this is a proposed mechanism, not proof that a workout eliminates metastasis or treats an established tumor.”

“Genetics plays an important role in longevity, but there is also a strong lifestyle component. Dr. Snyder's research, using deep molecular measurements, indicates that when you exercise, a profound molecular change occurs — particularly when it comes to immune molecules.”

“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.”

“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.”

“Exercise can improve blood pressure, insulin sensitivity, triglycerides, and fitness, but someone with high ApoB or LDL may still need targeted diet changes and clinician-guided lipid-lowering treatment. Mood is another major benefit.”

“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.”

“A large meta-analysis found that protein supplementation improved resistance-training gains in muscle size and strength, with little additional lean-mass benefit above an estimated total intake of about 1.6 grams per kilogram per day for most participants.”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“The body has elegant mechanisms that allow it to utilize non-carbohydrate substrates to generate glucose. Gluconeogenesis is a metabolic pathway in which the liver produces glucose from non-carbohydrate substrates including glucogenic amino acids (from protein) and glycerol (from lipids).”

“Dr. Patrick then prioritizes lower-glycemic-load, less-refined foods and adequate fiber. Early time-restricted eating can help some people reduce calories and may influence selected metabolic markers, but it is not required and must still preserve protein and diet quality.”
