Day 8 — Entering Week 2: The Truth About Extended Fasting & Human Limits

Welcome to Day 8 and the official start of Week 2! We have officially crossed the first major milestone of this one-year fasting journey, and as we head into week two, the mental and physical reflections are compounding.

Is there a loose correlation between extended fasting and animal hibernation?

Day 9 — 21 Ketones onof My 1-Year Fast

Day 9 of my journey to fast 3 days a week for 52 consecutive weeks. Today, I’m taking my breath-based ketone reading, and the results are 21 PPM!

Hitting a 21 on a breath ketone reader means my body is in ketosis, actively shifting from burning glucose to burning stored body fat for fuel.

As I share in a previous video, my recent DEXA scan was a massive wakeup call, showing a very high BMI and body fat percentage.

Day 10 — using a hydrogen water bottle

Does hydrogen water actually help compound the positive effects of fasting? I’m breaking down how I use it, how it makes me feel, and whether it’s making a difference.

A Quick Note on the Fatigue

Feeling lethargic around Day 10 is completely normal!

Day 11 — Marmite, Ketones, & Staying Alive! 🇬🇧

Welcome to Day 11 of the One Year Fast! Today, I’m breaking down a quintessential British staple that keeps me going on my non-fasting days: Marmite. 🇬🇧

As a vegetarian navigating this One Year Fast protocol, keeping my Vitamin B12 levels optimal is absolutely essential. In this episode, I share exactly why this love-it-or-hate-it spread is my secret weapon for B12 supplementation, how I incorporate it into my eating windows.

We are also checking in on the numbers! I'm measuring my current ketone levels to see exactly how my metabolic switch is performing as we move deeper into week 2.

Day 13 — Prepping for 4th of July celebrations

Welcome to Day 13 of the One Year Fast! I am feeling brilliant both physically and mentally. To refuel on this eating day, I had a nutrient-dense vegetarian stew. A vegetarian diet works in tandem with this 52-week fasting protocol.

With the 4th of July just around the corner, I’m reflecting on my journey as a UK & US dual citizen. I moved from the UK to the United States over two decades ago, and today I’m sharing a few reflections!

I have genuine respect and admiration for the people of the United States. Historically, the American spirit is incredibly pioneering, free-spirited, and strong-minded which is a little in contrast to the UK, where the monarchy subtly keeps societal dynamics a bit more structurally contained.

We are rapidly approaching a massive demographic tipping point: When will there be more people in existence who ONLY know an internet-dominated world versus those of us who remember a time before it? What happens to a civilization when its pre-connected history is completely erased from living memory?

1. The Global Demographic Balance (50/50 Split)The true tipping point of the digital age is determined by the global median age, which in 2026 sits at exactly 31.1 years old. Born Since the Internet Age (Under ~31): Roughly 4.15 billion people (50% of the world) were born in or after 1995. They have absolutely no biological or cultural memory of a world without digital connectivity. Lived Before the Internet Age (Over ~31): Roughly 4.15 billion people (50% of the world) were born before 1995. This group possesses the unique, historical cognitive archive of what human life, boredom, and community felt like before mass connectivity.

Day 14 — Fasting Completely Changed My Training & 4th July Iroquois Confederacy + Edgar Cayce

Happy 4th of July, everyone! Today marks a massive milestone for the United States as we celebrate the historic 250th anniversary of independence 🇺🇸. It’s a beautiful day of reflection, and perfectly timed as I officially enter Week 3 of the One Year Fast tomorrow!

We are officially two full weeks into this 52-week documentary protocol, and the biological shifts are starting to manifest in ways I completely didn't expect—especially in the gym.

For years, my fitness routine has been focused primarily on aerobics and light-weight "vanity exercises"—things like bicep curls, lateral raises, rear delts, tricep pushdowns, and dips. But over the last few days, something clicked biologically. I’ve felt a compulsion to move away from isolation movements and use core compound exercises.

1776 & THE HIDDEN ROOTS OF DEMOCRACY

Because today is the 250th anniversary of the Declaration of Independence breaking away from the British Monarchy, I wanted to reflect on a fascinating piece of history regarding our founding documents.

The subsequent formation of the American republic was profoundly influenced by the Haudenosaunee (Iroquois Confederacy) and its Great Law of Peace—the world's oldest continuous participatory democracy. When the Founding Fathers struggled to unite thirteen independent colonies, they looked directly to this centuries-old model of a federal system, where individual nations retained local sovereignty while uniting under a central grand council. Benjamin Franklin explicitly cited the strength of this Indigenous union when urging the colonies to unify, and the U.S. Congress officially acknowledged in 1988 that the structure of the American government was heavily inspired by the political sophistication of the Iroquois Confederacy.
