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 this calculator to compare how Estimated TDEE and Daily calorie deficit change Daily calorie target, Weekly calorie deficit, and Theoretical weekly change, and to review alternative values before using the estimate for planning.
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. Review the units and assumptions before interpreting the result.
