Day 22 — The Ecumenical Angle ⛪ + Splitting Cardio & Weights on Fast Days
Day 22 of the One Year Fast project — a fasting day log with the readings taken that day.
July 12 – July 18, 2026 · Days 22–28 · 7 entries
Days 22–28 of the One Year Fast project, written up day by day: three full fasting days in the week, what happened on each of them, and the weight, blood pressure and ketone readings recorded on those dates. Every figure shown here is measured on the day, not reconstructed later.

Day 23 · Monday, July 13, 2026
Today’s log is all about upgraded tracking hardware and diving deep into the powerful role that specific plant compounds play in supporting cellular health during an extended fasting protocol.
If you watched my logs last week, you know I was running into some erratic readings and calibration issues with my previous testing setup. To keep our open-source data entirely accurate, I’ve officially upgraded to a brand-new ketone reader. Noy overly impressive results!
MY OBSESSION WITH ARONIA BERRY (CHOKEBERRY) JUICE
Today I’m also sharing why I absolutely love organic Aronia Berry (also known as Chokeberry) juice, which has become a staple in my nutritional windows. When it comes to functional nutrition, Aronia berries are an absolute powerhouse. They boast one of the highest ORAC (Oxygen Radical Absorbance Capacity) scores of any fruit, meaning they are packed with exceptionally high levels of polyphenols and anthocyanins.
During eating windows on a long-term fasting framework, your cells are highly primed for nutrient absorption. Supplementing with high-polyphenol foods like Aronia juice provides an incredible burst of antioxidants to combat oxidative stress, support vascular health, and modulate inflammation—perfectly complementing the cellular cleanup achieved during my fasting windows.
Physically, everything is firing on all cylinders. The new alternate-day training split we introduced yesterday (aerobics on fasting days, weight bearing on eating days) is already yielding fantastic initial data points on my dashboard. Energy levels are perfectly linear, sleep tracking is optimal, and the new meter confirms we are deeply locked into a highly efficient fat-adaptation phase.
Day 24 · Tuesday, July 14, 2026
In today's log, I’m navigating a bit of a physical dip, but utilizing the quiet focus that comes with this stage of a fast to dive into a piece of history that hits incredibly close to home.
Today my mind wandered to the dramatic events of April 14, 1471. The Battle of Barnet was a decisive engagement in the Wars of the Roses, fought in a blinding morning mist just north of London.
This particular piece of history has a very personal connection for me, as I was born in Barnet. It is fascinating to look back at this incredible tactical mystery that happened right where my own story began—discussing how heavy fog caused confusion, friendly fire, and an unexpected rout on the battlefield, showing just how quickly the course of history can turn on a single mistake.
On the physical side of the protocol, I have to be completely candid: today I am feeling lethargic. The energy levels aren't quite as linear as they were earlier in the week, which is a natural wave to ride during a long-term alternating regimen.
Performing aerobic training during the fasting days to maximize fat oxidation.
Reserving intense weight bearing for non-fasting days to optimize recovery and structural repair.
When you're feeling lethargic, listening to your biofeedback is everything. I am logging how my body responds to today's aerobic session under this lower-energy state to see what exact results are achieved as we push forward.
Day 25 · Wednesday, July 15, 2026
Today's log is a continue look at an oddly performing Ketone Reader and reflecting on England's loss to the majestic Messi!.
Just when I thought we had our tracking completely dialed in with the new ketone reader, today brought a fresh set of challenges. I’ve been running into some unexpected readings with the new unit right out of the gate. When you're documenting a longitudinal study like this, faulty data is frustrating.
To clear my head from the tech frustrations, I found myself reflecting on a different kind of frustration—looking back at England's 2-1 loss to Argentina in the World Cup Semi-Finals in Atlanta.
I wonder whether Footballers fast prior to a match???
WEEK 4 PROGRESS & DATA CHECK-IN
Despite the minor headache with the reader, the underlying physiology is solid. The alternating aerobic and weight-bearing schedule is keeping my recovery highly manageable, even on days when the physical energy takes a slight dip.
Day 26 · Thursday, July 16, 2026
The One Year Fast Protocol. If you are new to the channel, welcome! The One Year Fast is my personal protocol where I fast for 3 days per week for 52 consecutive weeks. The beauty of this protocol is flexibility—I choose which days during the week to fast based on how my body feels and my weekly schedule.
Today marks Day 26. I’ve just come off a 48-hour fast. Interestingly, my ketone readings came in much lower than expected this time around. To gently ease my digestive system back into gear, I’m breaking the fast with a nutrient-dense, vibrant Spirulina and Hemp-based protein smoothie.
During my fasting window, my mind has wandering and wondering, and today I’m reflecting on the potential benefits of partitioning California into three separate states (a concept popularized by proposals like Tim Draper’s 2018 "Cal 3" initiative).
What do you think? Would a three-state California be a masterstroke of modern governance, or an administrative nightmare? And what would you name the 3 new states?
Day 27 · Friday, July 17, 2026
Apologies for the delay on this one, everyone. The One Year Fast Protocol. For those tracking the journey, the One Year Fast is my structured framework where I fast for 3 days per week across 52 consecutive weeks. The scheduling is completely flexible, allowing me to choose exactly which days to fast each week based on how my body is performing and what my schedule demands.
Even though this video is dropping a little late, the insights from Day 27 are crucial. Today, I'm evaluating my mental, emotional, and psychological health.
Fasting isn't just about watching the scale or counting the hours—it's an intense psychological experience. In this episode, I walk through how I am tracking these mental and emotional states to see how they truly align with my underlying biometrics.
Mental Clarity vs. Biometric Data: How cognitive focus correlates with heart rate variability (HRV) and sleep quality during fasting windows.
Fasting acts as a mirror for both physical and mental well-being, and today’s data shows some incredibly interesting trends when we map the psychological side directly to the numbers.

Day 28 · Saturday, July 18, 2026
Why does modern politics attract the wrong crowd, and how do we change it? Welcome to Day 28 of the One Year Fast, where today’s fast-window reflection centers on systemic political corruption and a personal philosophy for change.
The One Year Fast Protocol
If you are tracking the project, the One Year Fast is a structured data-driven protocol where I fast for 3 days per week for 52 consecutive weeks. The framework is built on complete flexibility—I choose which specific days of the week to fast based dynamically on my lifestyle, weekly commitments, and biometric readings.
Today marks Day 28, and as the physical routine stabilizes, the mental clarity that comes with this protocol has opened up space for deep societal and personal reflections.
When you strip away the constant noise of the daily news cycle, the fundamental issue is a lack of equilibrium and character in governance. It's time to start talking about a coordinated movement to get decent people back into the rooms where decisions are made.
