Fat loss by daily maths. No diets, no forbidden foods, no goals to chase — an accounting system for your body. Enter your details below and every number on this page — calories, protein, steps, even your downloadable rules card — becomes yours.
Your pace sets the deficit: your normal day sits exactly that far below maintenance, your quiet day goes a little deeper, and a splurge day is capped at maintenance — never above. A splurge pauses progress; it never reverses it.
⚠ At this pace your normal day drops below 1,200 kcal — lower than most adults should run. Pick a slower pace; the trend doesn't care how fast you go, only that you don't stop.
AM — 7-day average
Every bite, every day
Daily ideal — floor 80 g
Every single day
Every morning you pick a day type. The wall on the right is your maintenance — the most you ever eat. Everything left of it is progress at your chosen pace; the red zone is the only place damage happens, so the system simply never goes there.
The card rebuilds itself live from your details — calories, protein, steps, maintenance. Save it to your phone. It's your whole system on one screen.
The tape-measure method (the US Navy formula). Measure first thing in the morning, before food: waist at the navel, relaxed, not sucked in; neck just below the Adam's apple. Uses the height and sex you entered above.
An estimate, not a scan — the Navy method typically lands within a few points. What matters is what it does over months, measured the same way each time. Sound familiar? Trust the trend.
🌙 Sugar roller coasters are real — but every morning you start fresh.
Glucose spikes after dinner are more manageable.
📉 Weight is like the stock market — volatile. Record daily. Trust the week-over-week trend.
Water retention is temporary — and alright.
🕐 First meal when you're really hungry — around 1 PM. Food builds momentum. Start early, spend early.
