How the Fasting Schedule Works

The rule

The project has one rule: three full fasting days in every week, for 52 consecutive weeks, beginning 21 June 2026. A week runs Sunday to Saturday. A fasting day is a full calendar day — waking to sleeping — with no food.

What is consumed on a fasting day

• Water, freely and deliberately
• Black tea and black coffee, unsweetened
• Electrolytes when needed, without calories where possible
• No food, no juice, no milk, no caloric drinks

Anything that departs from this — and it does happen — is written into that day's entry in the Chronicles rather than quietly left out.

What happens on the other four days

The remaining four days are ordinary vegetarian eating. There is no calorie target, no macro split and no attempt to standardise them. That is a deliberate limitation, not an oversight: the question this project asks is what a sustained three-day-a-week fasting pattern does to a normal life, not what it does under laboratory control.

What this measurement cannot tell you

A single reading is close to meaningless on its own. What matters is the shape of the series across a year, read alongside the fasting schedule, sleep, training and the notes for that week. Nothing on this site is presented as evidence that fasting caused a change: this is one person, with no control condition, and many things change over a year besides the fasting days.
