Week 7 – The “System Oscillation” Phase
Week 7 was characterized by significant weight swings. While my total weight loss progress remains impressive – with a total weight loss of 8.9kg from the start – this week saw a net loss of only 0.1kg. Not even worthy of note.

The Weigh-in
- Weight at Start of Week: 116.0kg
- Weight at End of Week: 115.9kg
- Weekly Progress: -0.1kg
- Total Progress: -8.9kg
It’s like a classic engineering problem of a “hunting” system. I applied a massive corrective force (a 3-day water fast), which caused a sharp drop, followed by an equally aggressive “overshoot” in consumption (cake and ice cream), leading to a spike in weight and systemic discomfort.
Let’s look at it in more detail…
- The Manual Override (Days 1–3): I had a very successful 3-day water fast. I could also see that I could use this fasting as a “standard operating procedure.” This shows the 21/90 rule is becoming ‘burnt-in’ and hardened as just another new way of life. Weight dropped to a low of 114.9kg.
- The System Shock (Day 3): I had an early-morning “purge”. In a fasted state, this is often the body clearing out residual bile or shifting electrolytes. This was essentially a system flush.
- The Overload (Days 4–6): Following the fast, the “fuel mixture” became too rich. The introduction of high-carb inputs (chocolate cake, crackers, ice cream) combined with high-volume intake led to a 117.5kg spike.
- The Diagnostic Reading: I was feeling “bloated” and “unwell.” In engineering terms, this is System Congestion. My metabolism, having been primed for fat-burning, was overwhelmed by a sudden surge of high-density glucose and volume, leading to a temporary “shutdown” of digestive comfort.
Analysis: Accountability & Calibration
I managed to rationalise my loss of control during the week, but then, in a fit of self-honesty I accepted them as “feeble excuses.”
But, no matter the excuses, this week was a lesson in Load Management. A 3-day fast followed by a Madras curry and chocolate cake is the equivalent of taking a car from a dead stop to redline in first gear. The engine survived, but the “Check Engine” light (the bloated feeling) came on for a reason.
The good news: I recognized the “bloated” feeling was due to volume as much as content. This is a warning for the future.
The Goal for Week 8: “Input Stabilization”
My goal for the upcoming week is to eliminate the volatility. I want to move away from “Surge and Crash” and toward Steady-State Operation.
The Protocol:
- Standardize the Re-entry: When I break a fast, I must use a “Low-Voltage” meal (low fat, zero carb – like scrambled eggs) and wait two hours before adding complexity.
- Implement the “Core Seven”: Stick strictly to my compliant meal list to remove the “Decision Fatigue” that led to the ice cream and crackers.
- Target Weight: Achieve a stable 114.5kg by the end of Week 8 by maintaining consistent windows without the “overshoot” on eating days.
Insight: “Stability is the precursor to efficiency. This week, I don’t need a massive fast; I need a predictable schedule. Let’s get the ‘bloat’ out of the system and return to a steady, downward trajectory.”
