Your calorie estimate is not automatically your food target

The short answer

A resting-energy number and a whole-day estimate describe different assumptions. Neither alone can prescribe what you should eat.

The Daily Energy Estimate (TDEE) helps you turn the inputs into an estimate you can inspect. The useful part is understanding which assumption drives the answer, rather than treating the largest number on screen as a decision by itself.

Work through an example

At 70 kg, 175 cm and age 30 with the +5 coefficient, resting energy is 1,648.75 kcal/day. A user-selected factor of 1.4 gives an illustrative 2,308.25 kcal/day before rounding.

The example uses explicit inputs so you can reproduce it. Replace them with your own measurements or assumptions, and keep the units consistent. A result can be arithmetically correct while answering the wrong question if the inputs describe something else.

Use this checklist

1. Check the units and understand which equation coefficient you selected.
2. Keep the resting estimate separate from the activity-multiplied scenario.
3. Read the limitations and discuss individual dietary needs with a qualified professional.

How the calculation works

Resting estimate = 10 × kg + 6.25 × cm − 5 × age + equation coefficient (+5 or −161). Illustrative daily energy = resting estimate × your activity-multiplier assumption.

The tool shows its result and supporting values together. Where an item must be bought or counted in whole units, read the rounded count as well as the underlying quantity. Display rounding is separate from real-world uncertainty.

The mistake to avoid

For educational adult use only; not for children, pregnancy or breastfeeding, and not a personal eating target. The activity factor is a heuristic, not a clinical measurement. Do not infer a diet or deficit from BMI.

Compare at least one realistic alternative input before making an important purchase or plan. If the result looks surprising, inspect the units, the source of each input, and what the calculation leaves out first.

A useful next step

Open the Daily Energy Estimate (TDEE) to try the example. You can also explore Running & Walking Pace for the next part of the workflow. The related tool is optional; using one estimate does not mean you need to make a purchase or change your routine.
