Start curious.
Get grounded.
No question is too basic. Understand what your estimate means, how activity fits in, and where its limits are.
A BEGINNER-FRIENDLY BASE01 What does TDEE mean?
Total daily energy expenditure is the energy you use over a full day. This tool first estimates resting energy, then applies an activity multiplier to estimate maintenance calories.
daily energy estimate = resting energy × activity factor
02 How should I choose an activity level?
Think about a normal week, including your job, walking, and exercise. Training-day counts are only rough examples: an active job and a desk job can have very different energy demands, even with similar workouts.
The multipliers run from 1.2 to 1.9. They are broad estimates, not measurements from an activity tracker.
03 Why might my actual needs differ?
The equation uses age, weight, height, and sex. It cannot fully capture individual body composition or daily changes in activity. Use the number as a starting estimate; it is not a guarantee or a personalized nutrition plan.
This calculator is for adults and is not designed for pregnancy or breastfeeding.
04 Are my calculator details saved?
No. Calculator inputs are processed in this page and are not submitted or saved by this tool. Reset clears the fields. Changing an input clears the result until you calculate again.
