Lightly activeExercise 1–3 days a week× 1.3752,450 kcal
Moderately activeExercise 3–5 days a week× 1.552,760 kcal
Very activeHard exercise 6–7 days a week× 1.7253,070 kcal
Extremely activeHard training twice a day or a physical job× 1.93,380 kcal

How TDEE is calculated

First your basal metabolic rate (BMR), the energy you burn at rest, using the Mifflin-St Jeor equation, which a review of BMR equations found the most accurate for most adults:

Then BMR is multiplied by an activity factor, from 1.2 for sedentary to 1.9 for very hard daily training. The result is an estimate, usually within about 10% for most people. Track your weight for two to three weeks and adjust by 100 to 200 kcal if it moves differently from what you expect.

Calories for your goal

Calorie targets that change with your training

Elevus sets calorie and macro targets from your body, your goal and your training days, and logs meals from a photo, a barcode, a nutrition label or your voice.

FAQ

What is TDEE?

Total daily energy expenditure: all the calories you burn in a day, including your resting metabolism, daily movement, exercise and digesting food.

How accurate is a TDEE calculator?

Usually within about 10% for most people. Use it as a starting point, then adjust based on how your weight changes over two to three weeks.

Should I eat my TDEE to lose weight?

No. Eating at your TDEE maintains your weight. To lose fat, eat about 20% less; to build muscle, about 10% more.

What is the difference between BMR and TDEE?

BMR is what you burn at complete rest. TDEE adds everything else: daily movement, exercise and digestion. For most people TDEE is 1.2 to 1.9 times their BMR.
