자주 묻는 질문

Why does a bigger daily deficit shorten the days needed?
A larger deficit burns through the 3,500-calorie-per-pound target faster, though very large deficits are harder to sustain and can affect muscle mass and energy levels.
Is weight loss linear in real life?
No — this is a simplified estimate. Actual weight loss often varies week to week due to water retention, metabolic adaptation, and other factors.
What inputs does the Weight Loss Calculator need?
You'll need to provide: Current weight (lb), Goal weight (lb), Daily calorie deficit. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Weight Loss Calculator?
The Weight Loss Calculator applies the formula exactly as calculated — Pounds to lose = current weight − goal weight. Days needed = (lb to lose × 3500) ÷ daily calorie deficit, using the standard 3,500 kcal ≈ 1 lb of fat approximation. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is this a medical diagnosis?
No. The Weight Loss Calculator provides an estimate based on standard formulas and general population data, not a medical diagnosis or personalized clinical advice. Individual results can vary — consult a doctor or other qualified healthcare provider for medical concerns.
Is the Weight Loss Calculator free to use?
Yes, the Weight Loss Calculator is completely free, requires no signup, and runs instantly in your browser.
