Applied experiments in fasting, endurance, and executive performance.
How a Challenge Works
Every challenge begins with a baseline. I measure what matters — heart rate variability (HRV), resting heart rate, glucose levels, body composition, sleep, and subjective energy. Each data stream is tracked daily across wearables, lab tests, and structured logs.
This disciplined measurement creates the foundation for every adaptation that follows — because improvement without quantification is just guesswork.
Metric | Method | Frequency |
|---|---|---|
HRV / Resting HR | Fitbit 5 | Daily |
Glucose / Ketones | Fasting logs & meter | During fasting windows |
Sleep / Recovery | Fitbit + subjective journal | Daily |
Weight / Body Comp | Smart scale | Weekly |
Brands who build precision tools for measurement are the enablers of every insight that follows.
Once data reveals a pattern, I adapt. Nutrition windows, training load, and recovery timing evolve according to measurable response — not routine. When stress, travel, or sleep debt shift my metrics, the protocol flexes instead of breaking.
This iterative feedback loop turns lifestyle into a living experiment — an applied model of adaptive performance that sponsors can visibly quantify and showcase.
Example Sub-Metrics:
Adjusted fasting window when HRV dips.
Reduced training intensity during low recovery periods.
Incremental protein refeed after long fasts.
Innovation partners can integrate wearable feedback, predictive recovery, or AI-driven analytics directly into these adaptive cycles.
Each challenge can be framed as an active research project and it tests one hypothesis about performance. A typical protocol lasts 60–90 days and includes:
- A defined goal (for example, a fasted marathon or glucose stability under travel).
- Continuous biometric tracking from wearables and lab tests.
- Baseline and endpoint body-composition scans.
- Public documentation of data and insights.
Challenges are not competitions in the general sense, but instead, they are structured experiments in sustainable human energy.
Every challenge begins as a question worth measuring.

Istanbul Half Marathon (April 19) — Next Proof Event
A travel-week training block built to survive real schedules: time zones, meetings, imperfect sleep, and fasted runs. The outcome isn’t just race time — it’s repeatability under constraint, documented with measured reporting.

Fasted Marathon Project
Endurance in a fully fasted metabolic state.
A long-cycle experiment testing how structured fasting and aerobic training interact under real travel and work stress. Biometric data, body composition, and cognitive focus are tracked from baseline through race day and recovery. The goal is not just completion, but a clear map of what fasted endurance does to performance and resilience.

6-Pack Challenge
Visible recomposition under executive workload
This challenge measures how far body recomposition can progress while maintaining fasting windows, global travel, and normal work intensity. Metrics include body fat percentage, lean mass, waist measurements, and subjective energy during training. It treats aesthetics as a byproduct of disciplined protocol, not the primary target.

Family Challenge
Shared routines as a metabolic system
An experiment in applying structure to a household instead of an individual. The project tests how aligned sleep, meal timing, and movement affect overall energy, mood, and recovery across the family. Data is anonymized, but patterns in steps, sleep overlap, and routine stability are tracked over time.

Fasted Half Marathon – 36-Hour Fast
Endurance performance after extended fasting.
A controlled test of half-marathon performance after a 36-hour fast. Heart rate, perceived effort, and recovery time were monitored to observe how glycogen depletion and fat adaptation show up in real distance running. The results shaped the confidence to scale up toward the full fasted marathon project.

48-Hour Fast – Metabolic Shift
Tracking the transition to fat adaptation.
This protocol focused on the fuel switch itself: how glucose and ketone levels change over a 48-hour fast. Continuous readings documented the move from carbohydrate dependence to fat-based metabolism. The findings confirmed metabolic flexibility and provided a baseline for designing longer-term fasting structures.

Main Challenge
The Fasted Marathon Project
Exploring metabolic efficiency and endurance under prolonged fasting conditions.
This challenge asks a simple question: how far can endurance, focus, and metabolic health be sustained when fasting becomes a structured part of training and travel?
Over the course of the project, I track:
- Body composition.
- Resting heart rate, HRV, sleep, breathing rate, SpO₂, and skin temperature variation via wearables.
- Training load and pace.
- Subjective focus and decision quality during work travel.
The objective is not to set a record. It is to understand how disciplined fasting protocols support or limit real-world performance.

Fat Blaster: Reset and Rebuild
Baseline protocol for metabolic reset.
The foundation of my personal metabolic challenge series began here — a protocol to reverse insulin resistance and re-establish metabolic flexibility. Through structured intermittent fasting, Unicity’s clinically validated products, and careful biomarker tracking, this phase defined the starting point for long-term endurance and healthspan.
Measured variables: fasting glucose, body composition, waist-to-hip ratio, hunger response, and energy stability.

Metabolic Shift: the 48 Hour Fast
Focused Intermittent Fasting to Combat Insulin Resistance
Implementing metabolic benefits under intermittent fasting conditions.
Two days of complete fasting tested the body’s ability to shift fuel sources — from glucose to fat. This experiment marked the beginning of fat adaptation and metabolic flexibility.
Both my wife and I tracked ketones, glucose variability, heart rate, and perceived effort across the 48-hour window.
Measured variables: ketone levels, HRV, energy stability, recovery time.

Fasted Half-Marathon
Focused Intermittent Fasting under extreme aerobic and anaerobic exercise conditions.
Implementing metabolic benefits under intermittent fasting conditions during a competitive half marathon.
Fasted Half Marathon — Performance Under Precision
Running 21.1 kilometers after a 36-hour fast, the conditions were cool, calm, and perfectly suited for metabolic testing. With no external fuel, every stride drew on fat adaptation and weeks of disciplined fasting practice. The result — a personal best time — proved not just endurance, but efficiency: the body running on data, focus, and metabolic alignment rather than calories.
