How long realistic fat loss takes
Sustainable fat loss runs at roughly 0.5–1% of your bodyweight per week. Push faster and you start losing muscle and stalling your progress, not just fat. This calculator turns your goal into a realistic number of weeks and the daily calorie deficit it implies.
The pace you pick sets the deficit: gentler paces are easier to live with and protect muscle; brisker paces get there sooner but demand more discipline and leave less room for error. Pick the one you can actually hold.
Frequently asked questions
How long will it take to reach my goal weight?
At a sustainable 0.5–1% of bodyweight per week, this tool gives the number of weeks for your goal and pace. Heavier starting weights lose faster at first, then slow as you get lighter.
How big a calorie deficit do I need?
This shows the daily deficit your chosen pace requires. As a rule of thumb, a roughly 7,700-kcal weekly deficit loses about 1 kg of fat — but don't chase huge deficits; they backfire.
Is it safe to lose weight fast?
Beyond about 1% of bodyweight per week you risk losing muscle, energy and consistency. Slower is usually faster in the end, because you actually finish — which is why the gentler paces exist here.
Why do results slow down over time?
A lighter body burns fewer calories, so the same deficit yields less loss over time — and early water-weight drops flatter the first weeks. Sophia re-checks your numbers as you go so your plan keeps pace with your body.
