Calculate your TDEE

What this TDEE result means

A 40-year-old woman at 165 cm, 70 kg, and a sedentary activity level has an estimated TDEE of 1,644 kcal/day. That is the approximate daily intake expected to maintain her current weight under the selected routine. The number is relatively modest, which makes the size of any calorie reduction especially important.

How the estimate is built

Since no body-fat percentage is included, the calculator uses Mifflin–St Jeor. The calculation is BMR: 10 × 70 + 6.25 × 165 − 5 × 40 − 161 = 1,370; TDEE: 1,370 × 1.2 = 1,644 kcal/day. The 1,370-calorie BMR covers estimated resting energy needs; multiplying by 1.2 accounts for a low-movement day.

A small activity change has a visible effect

At light activity, this profile’s estimated maintenance rises to 1,884 kcal/day. Moderate activity would put it at 2,124 kcal/day. That does not make a higher result better—it shows why the selected row must match a normal week. Regular walking, standing work, and exercise all count, while one unusually busy day does not redefine the routine.

What BMI can tell this profile

The calculated BMI is 25.7, in the general overweight range. BMI can flag a topic to explore, but it cannot determine body composition or whether weight loss is appropriate. If fat loss fits this person’s health goals, a short recommendation would be to start conservatively and monitor waist, average weight, energy, and strength. Medical conditions or symptoms should be discussed with a clinician.

The ideal-weight formulas estimate about 57.1–57.4 kg from height and sex. They do not consider muscle, fat distribution, previous weight history, or quality of life. They are not required targets.

The displayed cuts need extra caution

Maintenance is 1,644 calories, but the standard mild cut falls to 1,144 kcal/day and the aggressive cut to 894 kcal/day. Both trigger the calculator’s low-calorie warning. A fixed 500- or 750-calorie deficit takes up a large share of this profile’s maintenance needs, so neither card should be treated as the default. A smaller, individualized reduction may be more realistic.

Keep the macro plan flexible

At maintenance, moderate-carb provides about 123 g protein, 64 g fat, and 144 g carbohydrate. The other tabs redistribute the same calories; they do not make a very low target safer.

Use 1,644 as a starting estimate and compare it with two to three weeks of consistent intake and average weight. Adjust only after a clear trend emerges. The TDEE accuracy guide explains why this calibration matters. This page is educational, not individualized medical or nutrition advice.
