“Sure, those dates on the calendar pass at the same rate for everybody, but some people appear to age slower (or faster) than others – with vastly different age-related physical changes and disease risks.”

“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.”

“Patients assigned to supervised exercise during neoadjuvant chemoradiation, followed by continued activity before surgery, were more likely to achieve a complete or near-complete pathological response than those receiving usual care.”

“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.”

“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.”

“Dr. Patrick also describes a proposed anti-metastatic mechanism: faster blood flow during vigorous exercise increases shear forces on circulating tumor cells, the cells that have left a primary tumor and entered the bloodstream.”

“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.”

“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.”
