How it works

Two twos, two numbers

Eat twice. Move twice. Weigh twice. Under a minute a day of actual interaction, and nothing to count.

The Two Twos

Not a morning person, or not on a 9-to-5? The rule is really “last meal ends 8 hours after waking.” A 2pm cutoff is what that looks like if you wake at 6. Shift workers, night owls, and parents of newborns: preserve the ratio, not the clock time. The evidence is for an early window relative to your day.

The Two Numbers

delta = max − min

The delta is your overnight rate. It is mostly water: respiratory vapour, loss through the skin, eight hours with nothing coming in. We do not call it fat loss, because it isn’t. What it is, averaged over two weeks, is stable enough to plan against, and that is all it needs to be.

Days 1 to 14: the baseline

Run the protocol and log both numbers. No targets, no adjustments, no goals. The only instruction is do the thing and write down two numbers.

Fourteen days, not seven, because it covers a full fortnight of variance, catches at least one weekend, and for anyone who menstruates it spans roughly half a cycle, which is a known 2 to 5 lb water swing. Seven days is too noisy to trust.

On day 14 the app shows your average delta. That’s the moment the number stops being random and starts being yours.

Day 15 onward: one lever

From here you manage a single thing: tomorrow’s max. The app sets it from your delta and your chosen rate of loss, 1 lb a week by default, adjustable, and capped at 2 lb a week because that’s the top of the range the CDC calls safe.

targetMax = today’s min + your average delta − (weekly rate ÷ 7)

You eat and drink until you approach the ceiling, then stop. You keep logging your min so the delta stays calibrated and the trend line keeps moving. That is the whole discipline. You don’t count anything. You weigh, so you know.

What a day looks like

1. Wake. Bathroom. Weigh. Log your min. Twenty minutes of movement.
2. Meal one. Whenever you like.
3. Meal two. Done by 2pm (or 8 hours after waking). Twenty minutes of movement.
4. Before bed. Weigh. Log your max.

There is no failed day

This is a design principle, not a feature. If you ate at 9pm, you log 9pm. If you skipped a workout, nothing happens. If you went over your ceiling, the number is higher. The app says “Logged.” and nothing else.

No streaks, no chains, no badges for showing up, no red. Streak mechanics turn a measurement tool into a compliance tool, and compliance tools are exactly what make weight apps dangerous for the people they shouldn’t be used by. The data is observational. You are not on trial.
