Day 15 — Not In Ketosis? Reminiscing the 1980s East End London Markets
Welcome to Day 15 of the One Year Fast! Today marks the official start of Week 3 in this 52-week documentary protocol, and we are adjusting the strategy while troubleshooting some unexpected biometric data.
As we enter this third week, I am shifting the rhythm slightly to a structured alternating routine. For the next seven days, I am fasting on Sunday, Tuesday, and Thursday (three separate 24-hour fasting windows). This approach keeps the metabolism guessing while allowing for controlled, clean refeeds in between to fuel the heavy compound lifts we've been introducing.
We hit a bit of a data anomaly today. After being nearly 20 hours into the current fasting window, my breath-based ketone reader threw back a reading of flat ZERO. Biologically, after 20 hours of water fasting, the body should absolutely be producing circulating ketones as liver glycogen depletes.
Hitting the Week 3 milestone got me taking a trip down memory lane back to the East End of London. I found myself reminiscing about my younger days working down the famous Roman Road Market in Bow during the 1980s.
- WEEK 3 PROTOCOL CHANGES: THE 3x24 SCHEDULE
- THE KETONE PUZZLE: READING ZERO
- Conclusion: My old breath-based meter is likely failing, losing its calibration, or simply struggling to accurately register breath acetone levels at this stage of fat adaptation. To ensure the integrity of our open-source clinical data, I am upgrading the hardware immediately. I’ll be ordering a new breath analyzer and picking up some reliable urine strips to cross-verify the numbers and accurately troubleshoot this stall over the next few days.
