Giselle Petzinger, MD, an associate professor of Neurology at the University of Southern California and today’s guest, studies the extensive effects of how different types of exercise, in particular skill-based exercise, can affect the clinical outcome for people with Parkinson’s disease. Dr. Petzinger's work focuses on understanding how to promote brain repair after injury, particularly in the context of Parkinson's disease. She is currently investigating ways to enhance neuroplasticity in a preclinical model of the disease. She has examined the role of exercise in Parkinson's disease, with emphasis on how different types of exercise affect distinct regions of the brain. Her work has implications for improving the quality of life of patients diagnosed with the neurological disorder — a condition for which there is no cure. In this episode, we discuss... 00:06:57 - What is Parkinson’s disease? 00:11:57 - How symptoms of Parkinson’s disease generally only appear when ~50% of dopamine-secreting neurons in substantia nigra are lost. 1 00:14:57 - How other circuits in the brain can compensate for the loss of function of the substantia nigra. 00:18:37 - Prevalence and hereditary risk factors of Parkinson’s disease. 00:21:25 - How epidemiological studies have linked increased Parkinson’s disease risk with exposure to pesticides, herbicides, solvents, and certain heavy metals such as manganese. 1 00:26:57 - How exercise can lower the risk of developing Parkinson’s disease. 1 2 3 00:35:38 - How skill-based exercise, such as yoga, Tai chi, boxing, tango or skateboarding may play a special role in ameliorating some of the effects of the disease by driving circuit-specific effects, by creating top-down cognitive challenge for skills involved in a patient's movement through space. 00:47:49 - How serum BDNF significantly increases in Parkinson’s patients after 1 month of treadmill exercise and why this might mean better cognitive function. 1 2 00:58:33 - How treadmill exercise with heart rate 80-85% maximum for at least 3x per week slowed the progression of Parkinson’s disease symptoms. 1 01:01:31 - Why exercise may not fully replace the use of medications. 01:09:58 - How the omega-3 fatty acid DHA has some preclinical evidence suggesting it may reduce motor-symptoms and dyskinesia in Parkinson’s disease. 1 2 3 4 01:12:12 - How patients with Parkinson’s disease have higher levels of inflammatory biomarkers and how this might contribute to the disease. 1 Click here to get this episode's show notes and transcript Get early access with the premium members early access podcast feed, monthly Q&A sessions, an exclusive bi-weekly science digest email, and more!

David A. Sinclair, PhD, is a professor in the Department of Genetics at Harvard Medical School and co-director of the Paul F. Glenn Center for the Biological Mechanisms of Aging. He is the co-founder of the journal Aging, where he serves as co-chief editor. Dr. Sinclair's work focuses on understanding the mechanisms that drive human aging and identifying ways to slow or reverse aging's effects. In particular, he has examined the role of sirtuins in disease and aging, with special emphasis on how sirtuin activity is modulated by compounds produced by the body as well as those consumed in the diet, such as resveratrol. His work has implications for human metabolism, mitochondrial and neurological health, and cancer. In this episode, we discuss... 00:17:59 - How caloric restriction, fasting, and exercise increase levels of a molecule called NAD+ and how this activates sirtuins, a family of genes involved in longevity. 00:21:47 - How NAD+ levels and sirtuin activities decrease with age, and how animal studies suggest that raising cellular NAD+ levels can trick the body into thinking it is younger. 00:23:03 - How resveratrol enhances the binding of sirtuins to NAD+ thus making sirtuins more easily activated for a longer period. 00:27:36 - We also discuss Steve Horvath's epigenetic aging clock, which measures DNA methylation groups, and how they may play a role in widespread gene regulation, including sirtuin genes, and how NAD+ may participate in resetting the clock. 00:31:54 - How the signal that resets the epigenetic clock in mice involves the Yamanaka factors -- a group of four transcription factors that can reprogram an adult cell to become a pluripotent stem cell that can form any cell type. 00:46:48 - How resveratrol is a xenohormetic compound and is produced when grape plants are stressed either in response to fungus or lack of water. 00:55:35 - How a phase 2 clinical trial involving people with Alzheimer's disease showed resveratrol improved cognitive function, improved cerebrospinal fluid amyloid beta levels, lowered markers of activated microglia, and more. 00:58:03 - How both nicotinamide riboside and nicotinamide mononucleotide have been shown to improve cognitive function and brain pathology in mice that have been engineered to get a disease similar to Alzheimer's disease. 01:06:19 - How older mice that were given nicotinamide mononucleotide experienced delayed aging in the liver, muscle, immune cells, eyes, and bones, but those that took a lower dose had improved mitochondrial function and enhanced physical performance. 01:01:22 - How there may be challenges in translating animal studies on nicotinamide riboside and nicotinamide mononucleotide to humans particularly due to the need to determine the dose required to promote health benefits.

Elissa Epel, PhD, is a Professor in the Department of Psychiatry at the University of California, San Francisco where she serves as the director of the Aging, Metabolism, and Emotions Center. Her research centers on the mechanisms of healthy aging and the associations between stress, telomere length, addiction, eating, and metabolic health. In this episode, we dive deep into the world of telomeres, the length of which is one of the useful biomarkers scientists have for getting a sense of the differences between how individuals or groups of individuals age. Telomere shortening is both a cause and a symptom of aging and plays key roles in not only how long we live, but in how well. Lifestyle factors such as poor nutrition and smoking can accelerate telomere shortening by generating oxidative stress and inflammation. Click here to get this episode's show notes and transcript.

Matthew Walker, Ph.D., is a professor of neuroscience and psychology at the University of California, Berkeley, and serves as the Director of the Center for Human Sleep Science. Formerly, Dr. Walker served as a professor of psychiatry at the Harvard Medical School. Walker's research examines the impact of sleep on human health and disease. One area of interest focuses on identifying "vulnerability windows" during a person's life that make them more susceptible to amyloid-beta deposition from loss of slow wave sleep and, subsequently, Alzheimer's disease later in life. Dr. Walker earned his undergraduate degree in neuroscience from the University of Nottingham, UK, and his Ph.D. in neurophysiology from the Medical Research Council, London, UK.

This podcast is a spectacular round two podcast with Dr. Valter Longo. Dr. Longo is the current director of the longevity institute at the University of Southern California and also director of the Oncology and Longevity Program at the Institute of Molecular Oncology Foundation in Milan, Italy. Dr. Longo’s research focuses understanding the biological mechanisms that regulate the aging process, the role of fasting and diet in longevity and healthspan in humans as well as metabolic fasting therapies for the treatment of human diseases. In this episode, we discuss... What two seminal studies on chronic caloric restriction in primates from the 80s teach us about caloric restriction as a preventer of age-related disease, and how the effects of caloric restriction may actually be stronger when the diet that is being restricted is an unhealthy one – similar, in some ways, to the typical western diet. How certain macronutrients influence the insulin/IGF-1/growth hormone axis interact to modulate aging in many cell types. How mice and humans who have growth hormone receptor deficiencies have low circulating IGF-1 – as little as 10% of normal levels – and have reduced risk of diseases like cancer, diabetes, and age-related cognitive decline, hinting at what future research might reveal about the beneficial effects of prolonged fasting and fasting-mimicking diets through the downstream effects of periodic deprival of growth-related factors. How the growth hormone / IGF-1 axis got a big boost early on in scientific interest when it was revealed that mice that have either deficiency in growth hormone itself or the growth hormone receptor live up to 40% longer and how this is accomplished through what is essentially a delaying of the decrepitudes of old age. The origins of what Dr. Longo calls the fasting-mimicking diet – a 5-day diet focused on recapitulating some of the benefits of prolonged fasting, like dramatic changes in metabolic biomarkers, but without some of the drawbacks like reduced compliance and other risks that can come with multiple days of grueling strict water fasting in large, heterogeneous populations. How periodic prolonged fasting or the fasting-mimicking diet may be able to render cancer cells more vulnerable while conferring stress resistance to healthy cells, a quality known as differential stress resistance. This can happen because of the way fasting interferes with what is known as oncogenic signaling. The mixed results associated with the use of the ketogenic diet in treatment of cancer and how some cancers seem to be hurt by the metabolic switch of utilizing ketone bodies, which creates oxidative stress from the use of mitochondria, while other cancers seem to be able to use ketones effectively as an energy source, potentially accelerating their growth. Some of the early but promising pre-trial clinical anecdata suggesting potential complementary roles for the ketogenic diet and the fasting-mimicking diet (FMD) used in conjunction with conventional treatments like chemotherapy or radiotherapy for certain cancers like gliomas. In the context of aging, how the fasting mimicking diet has been shown to “reset” metabolism, driving down biomarkers associated with poor metabolic health, inflammation, and cardiovascular health. How fasting, through the shrinking and then re-expansion of whole systems like the liver, kidneys, heart, and immune cells may represent a type of whole-system renewal that originated as a three-billion-year-old self-repair mode that was only activated during periods of famine or inconsistent food availability, but might now be dormant in people living in a modern world of regular food intake. How Dr. Longo’s group has shown that, in animal models of multiple sclerosis and pharmacologically-induced type 1 diabetes, several cycles of the fasting-mimicking diet is able to reverse disease and restore healthful function. This mechanism also may generalize to erasing other diseases of autoimmunity through the destruction of autoimmune immune cells that are essentially reset through fresh differentiation from progenitors untainted by autoimmunity. A very exciting area of continued inquiry! How shorter fasts may fail to approach some of the effects of periodic fasting and the fasting-mimicking diet by failing to achieve adequate glycogen depletion and ketogenesis. Dr. Longo’s “top picks” for assessing biological age – markers a person can ask their doctor to measure to gauge how well they’re aging.

Disappointing, not the info - that was interesting - although obviously aimed to be a cliffhanger/ trailer to having to paying for a premium version. Real disappointment comes from the scaremongering in SEPTEMBER 2020 (I might understand if it was in April) speaking paranoia about exercising outside & avoiding the apartment's sauna. This is reactive and not science-based, in fact there's gathering evidence that locking down & social distancing for the vast majority of the population, when there are so few serious cases or deaths (despite the case-demic) is clearly counter-productive & both has & will lead to more deaths. Get out in the sun Rhonda, stop being paranoid & help build yours & others immunity.

Excellent preview discussion about heat stress proteins. One thing about baths, to get the full effect it needs to be in the 110°F range but baths seem to be more adverse in health to reproductive organs in males mainly? Is this avoidable?

Smartest human on optimal health. The ability to research and remember these studies; then apply their information is uncanny. I wish you were in charge of public health. The world would be a better place. Not that it isn't already because of you and the people that you introduce us to in this. Thanks so much!

I have been trying Hemp oil, which has a high content of CBD and no THC. It seems to work quite well, it might be placebo but it's the best placebo I've ever seen. I take it once a week on a day that I can sleep as long as I want, I go to bed earlier. I sleep two hours longer, I almost double my deep sleep, increase my REM in half hour (according to my Huawei band 3 Pro), and fall asleep easier compared with a day with same conditions without the oil. I don't do it more often because I have found no studies to assure me that I won't create any other problems by inducing more sleep this way. Let me know if you know of any study on CBD.

Great info. thanks! I'm curious if this would have any impact on people who live in cold climates. Can being outside or exercising in the cold be considered to have the same benefits?
