Gravity may be the most ignored signal in human biology, and it could be the missing key to unlocking fat loss, brain optimization, and true longevity. In this episode, you’ll learn how Earth’s pull shapes your metabolism, mood, and resilience, and discover practical hacks to fight “gravity intolerance” so you can perform better, live longer, and upgrade every system in your body. Watch this episode on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR Host Dave Asprey sits down with Dr. Brennan Spiegel, a Professor of Medicine and Public Health at UCLA, Director of Health Services Research at Cedars-Sinai, and author of Pull: How Gravity Shapes Your Body, Steadies the Mind, and Guides Our Health. A leading voice in digital health and immersive medicine, Dr. Spiegel brings decades of clinical and research experience exploring the intersection of the gut-brain axis, neuropsychology, and mind-body medicine. In this episode, he reveals why gravity influences everything from gut health to depression — and why modern medicine has largely ignored its role. His work bridges functional medicine, neuroscience, and biohacking to uncover a hidden force that shapes human performance at every level. You’ll Learn: • Why gravity is the most ignored biohacking signal in human health • How gravity intolerance shows up as back pain, fatigue, obesity, and depression • The surprising connection between gravity, serotonin, and mood regulation • How weighted vests, balance boards, and proprioception training hack graviception • Why sleep optimization, posture, and fascia resilience are gravity-based health tools • How Earth’s pull influences gut health, metabolism, and even consciousness You’ll learn how gravity connects to obesity, back pain, blood pressure, serotonin, and even consciousness. Dave and Dr. Spiegel explore how weighted vests, balance boards, vibration, and sleep optimization can hack your body’s response to gravity. This channel dives into mitochondria, neuroplasticity, fasting, ketosis, supplements, and how biohackers can apply these insights alongside tools like cold therapy, nootropics, and even Danger Coffee to build resilience and extend longevity. Dave Asprey is a four-time New York Times bestselling author, founder of Bulletproof Coffee, and the father of biohacking. With over 1,000 interviews and 1 million monthly listeners, The Human Upgrade brings you the knowledge to take control of your biology, extend your longevity, and optimize every system in your body and mind. Each episode delivers cutting-edge insights in health, performance, neuroscience, supplements, nutrition, biohacking, emotional intelligence, and conscious living. New episodes are released every Tuesday, Thursday, Friday (audio-only), and Sunday (BONUS). Dave asks the questions no one else will and gives you real tools to become stronger, smarter, and more resilient.

Excellent points on the veganism debate. I only wish vegans were open to facts when discussing these things.
Hey Dave. Tell Tracy that his book is probably being shadow banned in Amazon. When you search for, it auto corrects to "Tracy Chapin" every time so it not something random. It shows something completly unrelated. Maybe his lawyers should look into this.

great podcast, thank you very much 😄
In the development of cybersecurity of satellite European systems, an important stage is regularly tested https://orbitaltoday.com/2023/04/26/satellite-hackers-seize-control-of-esa-satellite/ What disadvantages in modern satellites can be useful to spies and enemy hackers?
If you are looking to burn calories then less time equals less calories. So if that's your goal then this wouldn't be beneficial, correct?
Hi Dave, You mentioned in this podcast that you do NOT recommend psyllium as prebiotic fiber - at the same time on other podcasts you're promoting uprisingfood.com which has psyllium as one of their main ingredients. I'm a bit confused. Could you please help me to clarify this? Should I avoid uprisingfood.com products as they have psyllium in it? Thx.
I'm just wondering: if the infrared sauna heats the person up from the inside: 1. Then Why does a "cabin" needed to be built around it, why cannot it be just a wall panel, like the JOOVV 3.0 Red Light Therapy devices? 2. And if the "cabin" is indeed needless for the infrared Sauna, then why JOOVV or SUNLIGHTEN - or any other similar company don't build a device /wall panel which offers 2 in 1: both Red Light Therapy AND infrared sauna in one single device / single session? Would this be too difficult/expensive to build? Or would there be health risks to have infrared sauna and red light therapy session together, at the same time?
re: low T as a function of training intensity and recovery Highly recommend mark sisson's book primal endurance. Brad Kearns case presented in that book is right in line with this guy's experience.
watch soft white underbelly. tell them and the host of that show what you said in the peer's podcast about therapy. give them money to better their lives since you don't think they need some help. really disappointed in you Dave. you let me down. I will no longer praise you.
what you said about the therapy is so wrong and proves you are an not really a sufferer like you say. I followed you for years...years... not now. you have no idea what me and others have been through. You were fat and picked on, but what about a full trauma childhood, leaving you really mentally crippled. I liked you but now not so sure. you think anyone that had a awful upbringing or horrible experience can do it themselves. slight insult.
what you just said about the therapy is so wrong and proves you are an idiot. I followed you for yers...years... I am out. you have no idea what me and others have been through. wow. you are not in touch. thank you for showing me what type of person you are. I liked you but now no. you think anyone that had a awful upbringing or horrible experience can eR a carrot or spend your kind of money sitting in a tube of water and they get better. shame on you. someone last week said terrible things about you but I defended you but now what you Saud in the episode is an total insult.
really enjoyed this one. it continues to amaze me how otherwise intelligent well-informed people like the guest can remain so ignorant about this virus and the vaccine. I.e I e. overestimating the risk and uninformed about how useless and dangerous the vax has proven to be. not to mention completely uninformed about a middle or alternate path to addressing the public health issue. heaven forbid public health officials should encourage testing for vitamin d, inflammation and blood sugar regulation. or that they would advocate supplementation and holistic approaches to preparing oneself to win against the virus. heaven forbid they should advocate prophylactic treatment for those at high risk of exposure or infection. no way should this intelligent individual advocate for prophylactic use of proven effective early treatments
this is the first time someone has explained why memory palaces are useful in our day and age. time to clean off the vines.
That is so ualll conversation, i have a teen doughter, She had anorexia and i was trying teach her to make peace whit food with high fat diet is good for the brain and she used to feel less hunger less stressed . Learn with Dr Daniel Amen and i thought that was the best for her.. When she was at psychiatric clinic, they criticize my method i was begging for them not to give her white bread and sugary food becouse she gets into stress becouse od the craving, she also wants too, she keeping saying that she want to do fat diet and fell better this way, they dinied gave to her white flour and sugar and its not good for any those kids, They used every Tuesday teachs kids how to do candys and cakes... They didint exercised and sun shower only thru the window I was lost.. Sad.. puting my kid in sharks mouth.. Was in the best lisbon hospital at Portugal.. We are so far away.. Thank god that i found you and Peter Attia, Jason Fung Mark Hyman, Ben Bikman... 🙏
So precious.. Thanks 🙏💪
So interesting and nice topic, and very fun becouse last February I had 7 day fast on the beginning of the month and i also had 2 times 48 hours in the end of the month I did 5 day fast total I did 15 days without food i lost 5 kilos, and my period 😕 then I realize that I went to far..
