“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.”

“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.”

“In this excerpt from Dr. Rhonda Patrick’s A4M LongevityFest 2023 keynote, she reviews a randomized trial in sedentary middle-aged adults. Two years of progressive, supervised aerobic training increased VO2 max and reduced left-ventricular stiffness.”

“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.”

“Mounting evidence suggests that exploiting this property may be useful towards reducing the toxicity of chemotherapeutics while also maximizing their impact in the treatment of cancer.”

“Dr. Rhonda Patrick talks at SF Nerd Nite about transgenerational effects of caloric restriction on longevity, B-vitamins silencing bad genes, cognitive stimulation reversing neurodegenerative disease, exercise increases neurogenesis, and ways in which vitamin D might influence aging.”

“Severe sleep deprivation offers one such model. In a randomized crossover study of 15 healthy young adults, a single dose of 0.35 grams per kilogram changed brain-energy measures and reduced deterioration on selected cognitive tasks during about 21 hours awake.”

“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.”

“A later crossover study using a lower weight-based dose found its clearest benefit in reasoning, while several memory, accuracy, fatigue, and sleepiness outcomes did not reliably improve. Routine muscle supplementation and acute sleep-loss research use different protocols.”

“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.”
