Dr. Eric M. Verdin discusses the roles of the ketogenic diet, beta-hydroxybutyrate, HDAC inhibitors, NAD+, and more in the context of aging.

“Contrary to the traditional view of lactate as a metabolic waste product, it is now recognized for its critical role in brain health. Elevated lactate levels after vigorous exercise are linked to improved executive function, hinting at its potential protective benefits against neurodegenerative diseases.”

“A larger randomized-trial meta-analysis also found modest average reductions in BMI, waist circumference, and body-fat percentage, although protocols and populations varied. These averages do not mean that HIIT alone guarantees fat loss.”

“The physical activity guidelines and estimates on how much activity we need are heavily based on self-reported activity, which is useful but imperfect: people remember going for a run, but they forget the short, intense bursts in daily life like sprinting up stairs, chasing kids, and running to catch a bus.”

“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.”

“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.”

“A commonly observed behavior among mammals is the so-called "sickness behavior," where a person or animal that is sick will retreat, avoiding food and contact. This abstention from food induces autophagy and may serve as a means to modulate the body's inflammatory response.”

“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.”

“In this clip from his FoundMyFitness interview with Dr. Rhonda Patrick, Dr. Derya Unutmaz presents an optimistic vision in which AI, biotechnology, and rapidly improving treatments help more people remain healthy long enough to benefit from the next generation of therapies.”

“High energy demand is a promising research setting. In a randomized crossover study of 15 healthy adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed cerebral energy measures and improved selected cognitive outcomes.”
