What this TDEE result means

A 50-year-old woman who is 160 cm tall, weighs 65 kg, and is lightly active has an estimated TDEE of 1,704 kcal/day. This is the approximate daily calorie intake for maintaining weight at the selected activity level. Because the estimate is below 2,000 calories, large fixed deficits quickly produce very low targets.

How 1,704 calories is estimated

With no body-fat measurement entered, the calculator uses Mifflin–St Jeor. The calculation is BMR: 10 × 65 + 6.25 × 160 − 5 × 50 − 161 = 1,239; TDEE: 1,239 × 1.375 = 1,704 kcal/day. The 1,239-calorie BMR estimates resting energy use; the light multiplier accounts for routine movement and exercise.

Check whether the week is truly light

The sedentary result is 1,487 kcal/day, and moderate activity raises the estimate to 1,920 kcal/day. Light activity sits between those figures. Regular walking and a few easier workouts may support that choice, but exercise frequency is only part of the picture. Work, errands, step count, and time spent sitting also affect which row best represents the week.

A balanced view of BMI and weight

The calculated BMI is 25.4, within the general overweight range. BMI does not describe muscle, fat distribution, fitness, or how weight has changed over time. If reducing weight is appropriate for this person’s health goals, a small, sustainable deficit is a more useful recommendation than rapid loss. Waist, strength, energy, and average weight can provide a fuller view.

The ideal-weight formulas estimate about 52.6–54.1 kg. Those numbers come from height and sex alone. They do not account for menopause, body composition, medication, health conditions, or the weight at which someone feels and functions well.

Why a smaller deficit may fit better

Maintenance is 1,704 calories. The mild-cut card drops to 1,204 kcal/day, close to the calculator’s warning boundary, and the aggressive cut reaches 954 kcal/day, which triggers a low-calorie warning. These fixed reductions are large relative to maintenance. A smaller adjustment may be easier to nourish, follow, and evaluate. The sustainable deficit guide adds practical context.

Use macros as flexible options

At maintenance, moderate-carb provides about 128 g protein, 66 g fat, and 149 g carbohydrate. Other splits rearrange the same calories; they should support food preference rather than create another rigid rule.

Test 1,704 calories against two to three weeks of consistent intake and average weight. Adjust gradually only after a reliable trend appears. Age, menopause, medication, health, and activity can affect actual needs, so this educational example cannot replace personalized professional advice.
