What is TDEE?

TDEE stands for Total Daily Energy Expenditure. It represents the total number of calories your body burns in a day, including:

• Basal Metabolic Rate (BMR): The calories your body burns at complete rest.
• Physical Activity: The calories burned through exercise and daily movements.
• Thermic Effect of Food: The calories burned digesting and metabolizing food.

Knowing your TDEE is essential for creating a personalized nutrition plan. If you consume fewer calories than your TDEE, you'll lose weight. If you consume more, you'll gain weight. Maintaining your current weight requires consuming calories equal to your TDEE.

How to Calculate TDEE

Calculating your TDEE involves two main steps:

1. Calculate your BMR: This is the number of calories your body needs to perform basic functions at rest.
2. Adjust for activity level: Multiply your BMR by an activity factor to account for physical activity.

The most common formulas for BMR are the Mifflin-St Jeor Equation (for adults) and the Harris-Benedict Equation (older formula). The activity factors vary based on your lifestyle.

TDEE Formula

The general formula for TDEE is:

Where:

• BMR: Your Basal Metabolic Rate (calculated using height, weight, age, and gender)
• Activity Factor: A multiplier based on your daily activity level

Common activity factors include:

• Sedentary (little or no exercise): 1.2
• Lightly active (light exercise/sports 1-3 days/week): 1.375
• Moderately active (moderate exercise/sports 3-5 days/week): 1.55
• Very active (hard exercise/sports 6-7 days a week): 1.725
• Athlete (very hard exercise/sports and physical job): 1.9

How to Use This Calculator

Using this TDEE calculator is simple:

1. Enter your height in centimeters
2. Enter your weight in kilograms
3. Enter your age in years
4. Select your gender
5. Choose your activity level
6. Click "Calculate" to see your TDEE

The calculator will display your TDEE in calories and provide a breakdown of your daily calorie needs for weight management.

Example Calculation

Let's calculate the TDEE for a 30-year-old woman who is 165 cm tall, weighs 60 kg, and has a moderately active lifestyle.

1. Calculate BMR using the Mifflin-St Jeor Equation:

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

   BMR = (10 × 60) + (6.25 × 165) - (5 × 30) - 161

   BMR = 600 + 1031.25 - 150 - 161 = 1320.25 kcal/day

2. Apply activity factor for moderately active (1.55):

   TDEE = 1320.25 × 1.55 = 2050.38 kcal/day

This woman's TDEE is approximately 2050 calories per day. To maintain her current weight, she should consume about 2050 calories daily. To lose weight, she might aim for 1500-1800 calories, and to gain weight, she might consume 2200-2500 calories.
