The TDEE Calculator

The TDEE Calculator is a powerful tool designed to give you insight into the total amount of energy (calories) you expend daily. Your TDEE is based on various factors such as age, gender, weight, height, and activity level. By understanding your TDEE, you can optimize your caloric intake to match your weight goals, whether you aim to maintain, lose, or gain weight.

What is TDEE and Why is it Important?

Total Daily Energy Expenditure (TDEE) represents the total calories your body needs to maintain its current weight. Calculating TDEE allows you to tailor your diet and exercise plan for effective weight management. This information is essential for:

• Weight Loss: Eat below your TDEE to create a calorie deficit.
• Weight Gain: Consume more than your TDEE to achieve a calorie surplus.
• Weight Maintenance: Match your intake to your TDEE for stable weight.

Knowing your TDEE empowers you to make informed decisions about your nutrition and exercise, providing a foundation for sustainable health and fitness.

How to Use the TDEE Calculator?

Using our TDEE Calculator is simple! Just follow these steps:

• Enter Your Age, Weight, and Height: These factors are essential for calculating your Basal Metabolic Rate (BMR).
• Select Your Gender: This also influences your BMR, as males and females have different energy requirements.
• Choose Your Activity Level: From sedentary to highly active, your lifestyle significantly impacts your TDEE.
• Calculate: Hit "Calculate" to get your TDEE result in seconds!

Our calculator provides instant and accurate results based on the data you input, offering you a reliable estimate of your caloric needs.

Understanding the TDEE Formula

The TDEE formula combines your Basal Metabolic Rate (BMR) and your activity multiplier to provide an estimate of total daily calories burned. BMR is the number of calories your body requires to maintain basic physiological functions, like breathing and digestion. Once BMR is calculated, it is multiplied by an activity factor.

BMR Calculation Formulas:

Mifflin-St Jeor Equation: A common method for calculating BMR, which varies slightly between men and women.

• For Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5
• For Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) – 161

Activity Levels and Multipliers:

• Sedentary (little or no exercise): TDEE = BMR × 1.2
• Lightly active (light exercise/sports 1-3 days a week): TDEE = BMR × 1.375
• Moderately active (moderate exercise/sports 3-5 days a week): TDEE = BMR × 1.55
• Very active (hard exercise/sports 6-7 days a week): TDEE = BMR × 1.725
• Super active (very hard exercise, physical job, or training twice a day): TDEE = BMR × 1.9

Example Calculation:

User Data:

• Age: 30 years
• Gender: Female
• Weight: 65 kg
• Height: 165 cm
• Activity Level: Moderately active

Step 1: Calculate BMR

Using Mifflin-St Jeor for Women:
BMR = (10 × 65) + (6.25 × 165) − (5 × 30) – 161
BMR = 650 + 1031.25 – 150 – 161 = 1370.25

Step 2: Apply Activity Multiplier

TDEE = BMR × 1.55 = 1370.25 × 1.55 = 2123.89 calories per day

FAQs about TDEE Calculator

• What is the difference between TDEE and BMR? BMR is the baseline number of calories your body needs at rest to maintain vital functions, while TDEE includes calories burned from physical activity and daily movement.
• How accurate is the TDEE Calculator? Our calculator provides a close estimate based on commonly accepted formulas, but individual variations (like muscle mass or metabolism) may impact your true caloric needs.
