1. What is a TDEE Calculator for Weight Loss?

Definition: This calculator estimates your Total Daily Energy Expenditure (TDEE) based on your Basal Metabolic Rate (BMR) and activity level.

Purpose: It helps you understand how many calories you burn daily, which is essential for effective weight loss or maintenance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• TDEE — Total Daily Energy Expenditure (kcal/day)
• BMR — Basal Metabolic Rate (kcal/day)
• Activity Factor — Multiplier based on your activity level

Explanation: Your BMR is calculated using the Mifflin-St Jeor Equation, then multiplied by an activity factor to estimate total daily calorie needs.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you create a calorie deficit for weight loss (eat less than TDEE) or surplus for muscle gain (eat more than TDEE).

4. Using the Calculator

Tips: Enter your age, gender, weight in kg, height in cm, and select your activity level. The calculator will show your BMR and TDEE.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR?
A: Basal Metabolic Rate is the number of calories your body needs at complete rest to maintain basic functions like breathing and circulation.

Q2: How accurate is this calculator?
A: It provides a good estimate but individual variations may exist due to factors like muscle mass and genetics.

Q3: What activity level should I choose?
A: Be honest about your exercise habits. Overestimating activity leads to overestimated calorie needs.

Q4: How can I use TDEE for weight loss?
A: Consume 300-500 kcal less than your TDEE daily for safe, sustainable weight loss (about 0.5-1kg per week).

Q5: Should I recalculate my TDEE as I lose weight?
A: Yes, recalculate every 5-10kg lost as your calorie needs decrease with lower body weight.
