Request for Comments — weight-loss protocol

Data-Driven Weight Loss—Personalized Protocol Built on Your Biometrics

Finally, a system that tracks what matters and adapts to your unique physiology.

abstract

A 14-day kickstart, specified like software. We don't ask for a new you — we attach a handful of moves to commits you already make, and ship the first wins before willpower can fail.

daily active-time budget≈ 15 min

Allocated against the 90-minute plan you were sold and never had. The rest of the bar is the time you keep.

Motivation

Three problems observed in the field, filed before any solution was written.

The problem, stated plainly.

Not a motivation problem. A systems problem. Three failure modes show up in nearly every engineer and PM who tried to fix this with willpower — and lost.

openWL-A3-01#architecture

Sedentary by architecture, not by choice

You sit through 6 hours of meetings and the only walk you get is to the fridge. By 4 PM you've consumed 0 vegetables and 3 espressos. You're not sedentary by choice; you're sedentary by architecture.

openWL-A3-02#data-integrity

No commit messages on what you ate

Doom-snacking during sev2 incidents is the only stress release you have. You've tried calorie counting, but there's no data integrity to your eating. No commit messages. No recovery.

openWL-A3-03#scheduling

Apps assume a 6 AM you do not have

Every 'lifestyle' app assumes you have a flexible 6 AM wake-up for the 'ideal' routine. You don't. Your ideal morning is one where you don't wake up at 2 AM to page on something that could have waited.

§02

Specification

Normative requirements. The keywords MUST, SHALL, and SHOULD carry their RFC-2119 meaning.

Three clauses. Normative, not aspirational.

The same loop you already run on your work — calibrate, attach, retro — applied to your body. Here is the change it introduces, written as a diff:

your_week.diff
-willpower-based · 6 AM gym · restart every Monday
+attached to standup · pr_review · eod_merge · iterate Friday
  1. §2.1MUST

    Calibrate to your sprint cycle

    We map your protocol around your actual calendar: on-call weeks, planning weeks, ship weeks. The protocol changes. Heavy weeks are maintenance. Recovery weeks are adaptation. Like actual agile.

  2. §2.2SHALL

    Attach habits to commits and reviews

    Movements happen during PR reviews (stand, stretch, 2-minute walk between reviews). Meals are decided with git discipline (breakfast at standup, lunch before pairing sessions). No willpower; just architecture.

  3. §2.3SHOULD

    Weekly retro for your body

    20 minutes, every Friday. What worked. What didn't. Root cause (was it the week, or was it the protocol?). We iterate.

↻ WEEKLY ITERATE — ADJUST 3 THINGS, NEVER RESTART§2.1CALIBRATE§2.2ATTACH§2.3RETRO
Every loop closes on Friday. The retro feeds the next calibration, so the system corrects itself instead of asking you to start over.
§03

Rollout

first releases

The first releases, shipped across your 14-Day window.

Short and honest. Before the scale moves much, the build turns green — and you feel it in the 4 PM meeting and the 3 PM slump.

+First green build: small wins land — water during PR reviews, a breakfast that needs zero decisions.

§04

Validation

Acceptance tests run against the weeks that break ordinary diets.

Tested against the weeks that break plans.

A protocol is only as good as its worst week. Each of these is a real edge case — and a test the system is built to pass.

acceptance suite 5/5 passing
  • pass
    test · on_call_week

    Holds through an on-call rotation — maintenance mode, zero streak penalty.

  • pass
    test · offsite_travel

    Survives offsites: hotel-room circuit plus a 4-restaurant decision tree.

  • pass
    test · sev2_at_2am

    A 2 AM page does not revert the week — you resume at the Friday retro.

  • pass
    test · no_delta_30d

    No measurable change by day 30 → full refund, no friction.

  • pass

    Reimbursable at most tech employers — invoice template provided.

field report−13 lb / 96d
The Friday retro is the only ritual that survived a re-org and two on-call rotations. I stopped restarting on Mondays — there was nothing to restart, the protocol just kept running.

I don’t need motivation, I need something that tolerates a sev2 at 11 PM. First plan that treated a bad week as a logged incident instead of a personal failure.

Questions

Pre-cached. Every one has been filed in a retro before.

Filed before you could ask.

The four objections every engineer raises. Resolved, with no fine print.

Q01I'm on-call every 4th week. Can I still do this?
+

Yes. The program has 'maintenance mode' weeks designed around on-call. Most engineers actually lose weight during on-call because the structure forces it: you have a protocol, you don't improvise meals, you sleep better.

Q02I travel for offsites. Will this break the streak?
+

No. There's a travel protocol with hotel-room workouts and a 4-restaurant decision tree. You've shipped code from hotels; you can eat from a decision tree.

Q03I tried Noom. Is this different?
+

Noom is a generalist app. CENTUM is a cohort built for your calendar. Noom says 'drink water.' CENTUM says 'drink water during PR reviews because that's when you zone out.' Different goal.

Q04Will my employer reimburse this?
+

Many tech employers do via wellness stipends (Carta, Compt, Forma). We provide an invoice template. It typically shows as a wellness or professional development expense.

§06 · sign-off

Ship the first release.

A 14-day kickstart, assembled entirely from the calendar you already keep. The quiz takes two minutes, reads your real calendar, and returns a candid protocol you can run solo or with a cohort. No upsell mid-quiz. No shame copy.
