よくある質問

How was the −500/+300 calorie adjustment chosen?
A 500-calorie daily deficit approximates about 1 lb of fat loss per week; +300 is a moderate surplus for lean gains.
Which activity level should I pick?
Sedentary means little to no exercise; choose higher levels as your regular exercise frequency and intensity increase.
What inputs does the Daily Calorie Calculator need?
You'll need to provide: Gender, Age, Height (cm), Weight (kg), Activity level, Goal. 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 Daily Calorie Calculator?
The Daily Calorie Calculator applies the formula exactly as calculated — TDEE = BMR (Mifflin-St Jeor) × activity factor. Target = TDEE − 500 (cut), TDEE + 300 (bulk), or TDEE (maintain). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is this a medical diagnosis?

The Daily Calorie Calculator uses a real, verifiable formula — TDEE = BMR (Mifflin-St Jeor) × activity factor. Target = TDEE − 500 (cut), TDEE + 300 (bulk), or TDEE (maintain). — so results are accurate every time, not an approximation.
