Two months ago, I laid in a long, metal tube in a London hospital, staring at the blank white walls around me as the entire room buzzed and hummed with the sounds of high-tech analysis.

I was getting a "Magnetic Resonance Imaging" procedure done - also known as an "MRI". But this was no typical MRI. I wasn’t injured and I wasn’t sick: I was simply immersed in a brand new form of cutting-edge image analysis - an ultra-fast MRI scan to deliver precise quantification of fat and muscle tissue within hours - designed to give me a complete analysis of the entire structure of my body and brain - from extremely accurate body fat percentage and body fat distribution of visceral and subcutaneous fat, to the nitty-gritty details of everything from lean muscle and the brain, and beyond.

In today’s podcast, I'm going to take a deep dive into how you can do this type of advanced analysis of your body’s structure, the future of MRI testing for performance, longevity and aesthetics, and much more - including a very special appearance by Dr. Jack Kruse on how MRI's can be used to analyze something called the "redox potential" of the human body.

My first guest in this episode is Marcus Foster. Marcus spent most of his career as a Product Manager for technology companies, including 8 years at Google. In November 2011, he was involved in a serious cycling accident, breaking four ribs and his collarbone. He started playing around with 3D volume renderings of the CT scan that was done of his thorax as a result of the accident. He was blown away by how beautiful the human body looks on the inside. A year later he got knocked off his bike again, this time breaking his wrist, leading to another CT scan. The next year he was diagnosed with a tumor in his head and had to have a series of MRI scans. While he was gradually collecting imagery of different parts of his body, it seemed difficult to scale this model. In 2014, Marcus left Google and started Klarismo with the goal of making medical imaging more accessible to consumers as a means to explore and understand their own bodies.

My second guest in this episode, Dr. Jack Kruse, is a respected neurosurgeon and CEO of Optimized Life, a health and wellness company dedicated to helping patients avoid the healthcare burdens we typically encounter as we age. He is currently in private practice in the Gulf South. As a neurosurgeon, Dr. Kruse’s research has been published in respected dental and medical journals. His popular blog, JackKruse.com, gets over 250,000 unique worldwide visitors per month from countries like Australia, Germany, Russia, and Zambia (Africa).
