TDEE: 2155 kcal/day

What this calculator does

Total daily energy expenditure (TDEE) builds on BMR by multiplying for physical activity. Dietitians use TDEE to set weight maintenance, loss, or gain targets when paired with dietary assessment.

Formula and variables

Displayed formula: TDEE = BMR × activity

The engine evaluates: TDEE (kcal/day). Variable names match the input field keys so you can trace each step from entry to output.

How to use this tool

1. Open the Total Daily Energy Expenditure and enter your values using the units shown beside each field.
2. Review that inputs are within the typical physiological range before you calculate.
3. Read the result together with the interpretation notes below and your local clinical context.

How to interpret the result

Multiply BMR by an activity factor that honestly reflects lifestyle. Sedentary office work differs from manual labor or daily training. Revisit the factor when weight trends plateau unexpectedly.

Clinical context

Anthropometric indices support screening and counseling. They should be interpreted with diet history, activity, medications, and culturally appropriate goals.
