Reading time: 5 minutes
What I Discuss:
- My go-to walking setup, why I prefer a non-motorized, low-EMF treadmill, and how you can explore my full biohacking binder of home tools and gadgets…01:41
- How I’ve changed my sauna routine after learning that extreme heat may increase dementia risk, and why shorter, moderate sessions with a quick cold plunge are a smarter, healthier approach…04:49
- A brand-new study comparing dry sauna, infrared sauna, and hot water immersion, and the surprising result on which delivers the strongest heat-therapy benefits…08:06
- A new meta-analysis showing that about 7,000 steps a day delivers most major health benefits and that long, continuous sitting dramatically accelerates aging markers…15:14
- A new analysis reveals that when it comes to stubborn gut problems, the most effective non-drug therapies are diet change and fecal microbiota transplantation (FMT), which continue to show impressive results across a range of GI conditions…22:34
- A new look at high-dose oral FMT, and the entire step-by-step protocol I’m doing right now, including gut prep, capsule timing, and how the treatment is supervised…30:45
- A surprising study revealing that many “gluten symptoms” are actually nocebo-driven and why proper food-sensitivity testing is crucial if you truly want to know what your body reacts to…35:12
- Rumors around ketones and liver health, and how the evidence shows problems only at massive, unrealistic doses, far beyond anything humans would actually consume…38:28
In this fascinating solosode, you’ll get a behind-the-scenes look at how to build daily movement into your life, starting with why a non-motorized, low-EMF treadmill can be a powerful tool for energy and focus. You’ll gain access to my complete binder of home biohacking tools and gadgets designed to support long-term health and performance (click here to start exploring).
You’ll then dive into the evolving science of heat therapy and why extreme sauna temperatures may not be as beneficial as once thought. You’ll also discover why shorter, moderate sauna sessions paired with a quick cold plunge can deliver stronger cardiovascular and brain benefits, along with the surprising results of a new study comparing dry sauna, infrared sauna, and hot water immersion.
Next, I'll reveal what research really says about movement and gut health, including why around 7,000 steps per day delivers most of the key health benefits while prolonged sitting accelerates aging. You’ll also explore why diet changes and fecal microbiota transplantation (FMT) continue to show impressive results for stubborn gut issues, including a clear explanation of how high-dose oral FMT protocols are structured and supervised.
Finally, you’ll get clarity on some persistent health myths, including why many “gluten symptoms” may be driven by the nocebo effect and how proper food sensitivity testing can reveal what your body actually reacts to. You’ll also see why concerns about ketones and liver health are largely unfounded at realistic doses, helping you make smarter, evidence-based decisions about your health.

Ive had three fecal transplants for IBD in my life. The last one I got put me in remission for 2 years. Typically, cdiff runs high with people who have severe ibd. Ive actually written about it here https://www.biohackingblog.net/p/how-allopathic-medicine-almost-killed
Hi, do you have the info for the FMT capsules from Dr Matt Cook? Don’t see anything on the Reset Biomedical website. Thanks.
Hi Ben,
Thanks for all the tips on sauna benefits and the effects of sedentary ageing. My work is 90% sitting in front of 5 monitors watching the stock market.
It ruined my life from poor posture to ageing fast :(
Recently, I bought a vibration plate that I have under my desk and use when I work from home.
What’s your opinion on vibration plates? Do they work? AI says it works, but I need to hear it from an expert.
Thanks so much – Hannah
