Precision intermittent fasting timer.
FastHQ times your fasts to the second. No gamification. No upsells. Just the clock.
02 WHERE YOU ARE METABOLIC STATE
FastHQ shows you which metabolic phase you're in, in real time. The marker advances every second. Read the full fasted-state phase timeline →
Current: GLUCONEOGENESIS — liver synthesises glucose from non-carb sources. Glycogen near depletion.
03 SIX COMMANDS fasthq --help
COMMANDS
fasthq --protocol 16:8 # Default protocol — daily eating window
fasthq --protocol 18:6 # Tighter window for plateausPRO
fasthq --protocol OMAD # One meal a dayPRO
fasthq --protocol 24h # Extended fastPRO
fasthq --phase # Show current metabolic phase
fasthq --log # Past 90 days of fasts
Six commands. No menus. Every protocol is a single flag — built for fasters who already know what they want. Phase tracking and the 90-day log are first-class views, not buried features. Pro unlocks every protocol; the timer itself is always free.

05 HELP COMMAND fasthq --help --topic
> fasthq --help --topic "auto-detect"
No. FastHQ does not guess. You start the fast and you end it — that's the whole protocol. Auto-detection is the kind of feature that looks smart and then quietly logs you a 14-hour fast you didn't do. We won't ship that.
> fasthq --help --topic "phase-accuracy"
The phase tracker is a model, not a blood test. We approximate fasted-state transitions using elapsed time since your last meal — well-aligned with published literature on glycogen depletion (~12h) and the onset of ketosis (~18h), but real values depend on your last meal, training load, and individual physiology.
> fasthq --help --topic "notifications"
No. FastHQ will not pester you. We send one notification when your fast ends, and a second if you ask for a window reminder. No streaks, no badges, no "you've got this!" — open the app when you want the data.
> fasthq --help --topic "broke-my-fast"
Press stop. FastHQ records the fast at the exact second you ended it and logs it as complete or broken based on your target. Both are kept. Honest data is more useful than clean data.
> fasthq --help --topic "data-export"
CSV export of every fast you've ever logged. One row per fast, ISO 8601 timestamps. Yours, on disk, always.
> fasthq --help --topic "autophagy"
Autophagy — cells recycling damaged parts — is associated with longer fasts. FastHQ marks the autophagy band from ~24h. Be skeptical of exact numbers: much of the evidence is animal data, human timing is unsettled, and estimates vary. It's a model, not a measurement.
> fasthq --help --topic "ketosis"
Ketosis usually begins around ~18h as glycogen runs low — sooner if you're low-carb or training, later after a big carb meal. FastHQ marks it at 18h on the timeline. An estimate, not a blood reading.
> fasthq --help --topic "protocols"
16:8 is a 16-hour fast with an 8-hour eating window — the default. 18:6 tightens it to six. OMAD is one meal a day, roughly a 23-hour fast. Longer fasts reach further along the metabolic timeline. Each is a single flag; 16:8 is free, the rest are Pro.
> fasthq --help --topic "free-tier"
Yes — the 16:8 timer and your full log are free, with no ads, no time limit, and CSV export included. Pro ($3.99/mo) adds the other protocols, phase tracking, and a year of history. No trial gymnastics. Cancel anytime.
> fasthq --help --topic "offline"
The countdown runs on your device, so a dropped connection won't stop your fast or lose your place.
