1. What Is The TDEE Calculator?

The TDEE (Total Daily Energy Expenditure) Calculator estimates your daily calorie expenditure based on your Basal Metabolic Rate (BMR) and activity level. It helps determine how many calories you burn each day.

2. How Does The Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level

Activity Factors:

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

3. Importance Of TDEE Calculation

Details: Knowing your TDEE is essential for weight management, whether your goal is to lose, maintain, or gain weight. It provides a baseline for creating effective nutrition and exercise plans.

4. Using The Calculator

Tips: Enter your BMR in kcal/day and select your activity level from the dropdown menu. Ensure your BMR is calculated accurately for the best results.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR and how is it different from TDEE?
A: BMR (Basal Metabolic Rate) is the number of calories your body needs at rest to maintain basic physiological functions. TDEE (Total Daily Energy Expenditure) includes all calories burned through daily activities and exercise.

Q2: How accurate is the TDEE calculation?
A: The calculation provides a good estimate but individual variations exist. Factors like muscle mass, genetics, and specific activities can affect actual energy expenditure.

Q3: Should I use TDEE for weight loss?
A: Yes, creating a calorie deficit based on your TDEE is an effective strategy for weight loss. Typically, a deficit of 500-1000 calories per day leads to 1-2 pounds of weight loss per week.

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, your activity level changes, or every 4-6 weeks to account for metabolic adaptations.

Q5: Can TDEE change over time?
A: Yes, TDEE can change with age, weight fluctuations, changes in muscle mass, and alterations in activity levels.
