How to interpret this estimate

Compare a daily calorie deficit with a maintenance estimate. Target calories equal estimated TDEE minus the chosen daily deficit.

When this result is useful

Use it to compare a proposed calorie deficit with estimated maintenance needs and theoretical weekly change.

Common limitations

The theoretical conversion uses approximately 7,700 calories per kilogram and does not predict exact body-weight change. Energy needs and weight change adapt over time; aggressive restriction can be unsafe.

This calculator uses the selected inputs and the fixed formula behind the tool to produce an estimate. Review the units, assumptions, and result labels before using the output for planning.

Health results are screening or planning estimates only. They do not diagnose health status or replace advice from doctors, dietitians, or qualified healthcare professionals.
