“In later randomized trials, urolithin A improved some laboratory measures of muscle endurance or hamstring strength, but it did not significantly improve key primary outcomes such as six-minute walk distance, muscle ATP production, or peak power.”

“Large treadmill cohorts associate higher measured fitness with lower mortality, while a 46-year study of middle-aged men linked the highest fitness category with about 4.9 additional estimated life-years compared with the lowest category.”

“Across the modeled dose-response curves, one vigorous minute corresponded to 4.1 moderate minutes for all-cause mortality, 7.8 for cardiovascular mortality, 5.4 for major cardiovascular events, 9.4 for incident type 2 diabetes, and 3.5 for cancer mortality.”

“There's a lot of exciting research right now into aging and maximum lifespan, but scientists have really just scratched the surface of the fascinating topic of how to live longer, healthier lives. Relevant Publications Rootzén, Holger, and Dmitrii Zholud.”

“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”

Many of the anabolic effects of growth hormone are thought to be mediated by insulin-like growth factor-1, or IGF-1 (https://www.ncbi.nlm.nih.gov/pubmed/18500379), which is synthesized primarily in the liver but also in skeletal muscle in response to growth hormone.

“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.”

“If we eat carbohydrate-containing foods when melatonin levels are high, our pancreas cannot produce the insulin needed to use the glucose. Therefore, eating too close to bedtime or immediately upon waking, before nightly melatonin levels have declined, may hamper the body's ability to process glucose.”

“The mast cells release pro­inflammatory cytokines and proteases that damage the gut, leading to intestinal permeability, a condition otherwise known as “leaky gut.” This leakiness allows bacteria and bacterial antigens to cross the gut’s inner layer, the epithelium, and activate even more immune cells, leading to more inflammation – a key driver in the aging process.”

“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.”
