“When a cell is deprived of either its energy supply or the factors that help utilize energy, the cell resorts to drastic measures, sacrificing damaged or unnecessary parts to provide the things it needs to survive.”

“Lunch varied among sardines, mackerel, wild salmon, avocado, nuts, fruit, cheese, and quinoa salad, giving her flexible sources of protein, marine fats, fiber, and fermented foods. Dinner typically paired fish, chicken, or occasional beef with vegetables or salad.”

“Dr. Shinya Yamanaka discovered a group of proteins that can reprogram differentiated (mature) cells into pluripotent stem cells. These proteins, now called Yamanaka factors, are highly expressed in embryonic stem cells in mice and humans.”

“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).”

“Mouse studies of feeding during infection also found different responses across bacterial and viral models, so a minimally processed dietary pattern, regular exercise, and normal hydration and nutrition during illness provide a more useful foundation than one universal food or fasting rule.”

“00:29:20 - Organs shrink during fasting and then regrow after refeeding. Study. 00:29:45 - Fasting stresses healthy cells so they increase their stress-response pathways, including heat shock proteins, antioxidant production, and anti-inflammatory.”

“Some of the factors contributing to these variable phenotypes include persistent damage to our DNA and mitochondrial dysfunction, driven by an altered NAD:NADH ratio, the latter of which has recently been shown to be improved by certain dietary supplements like nicotinamide riboside.”

“In this brief episode, we learn how restoring our dietary and sleep pattern to one that more closely syncs with those imposed by nature, especially by avoiding eating within 2-3 hours before bed and onset of melatonin production, may improve our health and potentially prolong our healthspan.”

“Conversely, animal studies suggest that caloric restriction may slow epigenetic aging. In this clip, Dr. Steve Horvath describes research suggesting that caloric restriction in animals, although it is unclear this will translate to humans.”

“Specific topics include autophagy, the process of recycling dysfunctional cells that is induced by fasting and fasting-mimicking drugs such as resveratrol and spermidine. Rhonda discusses the effects of fasting on Parkinson's disease and which groups of people should not fast.”
