About This Calculator
This calculator converts a desired weekly weight-loss rate into an approximate energy deficit using 7,700 kcal per kilogram. Real-world weight change is not perfectly linear.
Formula & Notes
Estimated daily deficit = desired kg/week × 7,700 ÷ 7. Target calories = maintenance calories − daily deficit.
