What is TDEE?

Total Daily Energy Expenditure (TDEE) is the number of calories your body burns in a day, including physical activity.

What is TDEE and BMR?

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including all physical activities and basic bodily functions. It is the amount of calories you need to consume to maintain your current weight.

BMR (Basal Metabolic Rate) is the minimum number of calories your body needs to perform basic vital functions at rest, such as breathing, pumping blood, and maintaining body temperature.

Formula: TDEE = BMR × Physical Activity Factor

Mifflin-St Jeor Formula

This calculator uses the Mifflin-St Jeor formula, considered one of the most accurate for calculating basal metabolism. It was developed in 1990 and has been validated in multiple scientific studies.

Formulas:

Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5

Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

BMR is multiplied by a physical activity factor (1.2 to 2.0) to obtain TDEE.

Physical Activity Levels

Sedentary (1.2)

Little or no exercise. Desk work or minimal activities.

Light Exercise (1.375)

Light exercise 1-3 days per week. Activities like walking, light housework.

Moderate Exercise (1.55)

Moderate exercise 3-5 days per week. Exercises like running, swimming, moderate cycling.

Intense Exercise (1.725)

Intense exercise 6-7 days per week. Vigorous workouts, competitive sports.

Very Intense Exercise (1.9-2.0)

Very intense daily exercise, demanding physical work, or training twice a day.

Macronutrient Distribution

Macronutrients are the nutrients that provide energy to your body. The recommended standard distribution is:

Proteins

25-30%

4 calories per gram

Muscle building and tissue repair

Carbohydrates

45-55%

4 calories per gram

Main energy for body and brain

Fats

20-30%

9 calories per gram

Vitamin absorption and hormonal function

Calories for Different Goals

Maintain Weight

Consume exactly your calculated TDEE to maintain your current weight.

Lose Weight

Create a deficit of 500-750 calories daily to lose 0.5-1 kg per week in a healthy way.

Do not reduce more than 1000 calories without medical supervision.

Gain Weight/Muscle Mass

Increase 300-500 calories daily, prioritizing proteins to gain muscle mass.

General Recommendation

Drastic changes in calories can affect your metabolism. Consult with a nutritionist for a personalized plan.

Important Considerations

  • Individual variability: Calculated TDEE is an estimate. Your actual metabolism may vary ±200-500 calories depending on genetic, hormonal, and body composition factors.
  • Progressive adjustment: If you don't see changes after 2-3 weeks, adjust your calorie intake gradually (no more than 200 calories at a time).
  • Quality over quantity: Not all calories are equal. Prioritize nutritious and nutrient-dense foods.
  • Hydration: Water has no calories but is essential for metabolism and bodily function.
  • Additional factors: Stress, sleep, medications, and medical conditions can affect your metabolism and calorie needs.
