TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day, accounting for your basal metabolic rate (BMR) plus all physical activity. It is calculated by multiplying your BMR by an activity factor ranging from 1.2 (sedentary) to 1.9 (very active). Eating at your TDEE maintains your current weight; eating below it causes weight loss.

How many calories does the WHO recommend per day?

The WHO does not set a universal calorie recommendation — calorie needs vary greatly by body size, age, sex, and activity. Instead, the WHO recommends at least 150–300 minutes of moderate-intensity physical activity per week for adults. Country-specific guidelines (US Dietary Guidelines: 2,000 kcal reference intake; UK NHS: 2,000 kcal for women / 2,500 kcal for men) are population averages, not individual targets.

What activity multiplier should I use?

Most people overestimate their activity level. Sedentary (1.2×) = desk job, little movement. Lightly Active (1.375×) = 1–3 workouts per week. Moderately Active (1.55×) = 3–5 workouts per week. Active (1.725×) = hard daily exercise. Very Active (1.9×) = physical labor job plus training. When in doubt, choose one level lower than you think.

How does TDEE differ between countries?

TDEE is a physiological calculation that does not differ by country — the same BMR × activity formula applies globally. However, physical activity guidelines differ: WHO recommends 150–300 min/week moderate activity; the UK NHS mirrors this; the US CDC also recommends 150 min/week aerobic activity plus 2 days of muscle-strengthening. Japan's health guidelines historically emphasized 10,000 daily steps (about 150–200 min walking), which aligns with these targets.

TDEE Calculator

Total Daily Energy Expenditure (TDEE) is your BMR multiplied by your activity level — the actual calories you burn each day. Eating at TDEE maintains weight; eating below it creates a deficit.

Quick Answer

TDEE = BMR × activity multiplier. Sedentary (desk job, no exercise): ×1.2. Lightly active (1–3 workouts/week): ×1.375. Moderately active (3–5/week): ×1.55. Very active (daily hard training): ×1.9. To lose 0.5 kg/week, eat 550 kcal below TDEE. WHO recommends 150–300 min/week of moderate activity.

Frequently Asked Questions

What TDEE multiplier should I use for a desk job with gym 3×/week? ▾

Use "Moderately Active" (1.55×). A desk job with gym 3 times per week is one of the most common profiles. If you work out 3–5 days per week doing moderate-intensity exercise (45–60 minutes), this multiplier is appropriate. Note that if you are very sedentary outside the gym (driving everywhere, sitting most of the day), you might consider 1.375× instead.

How many calories should I eat to lose 1 pound per week? ▾

One pound of fat ≈ 3,500 calories. To lose 1 lb/week, create a deficit of 500 calories/day below your TDEE. Most health authorities (NHS, CDC, WHO) recommend not going below 1,200 kcal/day for women or 1,500 kcal/day for men without medical supervision. Aim for 0.5–1% of body weight per week as maximum safe fat loss.

Why is my TDEE different from the 2,000 calorie reference on food labels? ▾

The 2,000 kcal figure on US and EU food labels is a population average reference value — not a personal recommendation. The FDA chose 2,000 kcal because it approximates the average for adult women, making labels practical. Your actual TDEE may be 1,600–3,000+ kcal depending on your body size and activity level. The Australian NIP uses 8,700 kJ (≈2,080 kcal) as its reference value.

Sources & Methodology

Total Daily Energy Expenditure multiplies BMR (Mifflin–St Jeor) by a physical activity level (PAL). PAL ranges follow the FAO/WHO/UNU human energy requirements report.
