“In this clip, Drs. Levine and Patrick discuss genetic and environmental factors that can accelerate or slow epigenetic aging. Dr. Levine also discusses the aging clock she created and how it can be used, along with other biomarkers, to determine an individual's rate of aging.”

“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.”

“For people seeking better-supported ways to improve inflammatory health, she points to regular exercise, marine omega-3 intake, and sulforaphane-rich foods as practical areas with a larger human evidence base.”

“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.”

“A small magnetic-resonance spectroscopy study also found that 20 grams per day for four weeks increased brain creatine by an average of about 8.7 percent, showing that brain uptake is possible but variable.”

“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.”

“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.”

“Visceral fat can respond to changes in energy balance and physical activity. A meta-analysis of 40 randomized trials and 2,190 adults with overweight or obesity found that both exercise and calorie restriction reduced CT- or MRI-measured visceral fat.”
