Why there's a floor
When your goal is to lose weight, the app converts your chosen pace into a daily deficit — but never past a safety floor. Aggressive targets built on too little food cost you energy, mood, recovery, and adherence, so the calculator refuses to go there even if the pace you picked implies it.
There are two limits working together: the deficit is capped as a fraction of your expenditure, and calories are floored in absolute terms — the standard floor is 1500 kcal for men and 1200 kcal for women, and it also never drops below a large share of your estimated resting metabolism, so a bigger body gets a proportionally higher floor.
When the floor kicks in
If your pace asks for fewer calories than the floor allows, the app sets your target at the floor and tells you so — you'll see that your calories were adjusted to the minimum safe amount. Your real-world result: you'll lose a bit slower than the pace you picked, sustainably.
The lower-floor option
In the custom plan setup you can opt into an aggressive floor — 1200 kcal for men, 1000 for women. The app warns you when you pick it: low floors can affect energy, mood, and recovery, and it's worth involving a professional if you're unsure. If any of the situations in our Health Disclaimer apply to you, talk to one first.
When floors don't apply
Maintenance and gaining goals never touch a floor. And in Manual mode, where you type your own targets, the calculator isn't involved at all — the numbers are entirely yours.
