1. What is BMR and Calorie Deficit?

BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions. Calorie deficit is the difference between your Total Daily Energy Expenditure (TDEE) and your actual calorie intake, which is crucial for weight loss.

2. How Does the Calculator Work?

The calculator uses the following formulas:

\[ BMR = 10 \times weight + 6.25 \times height - 5 \times age - 161 \] \[ Deficit = TDEE - Calories \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( TDEE \) — Total Daily Energy Expenditure in kcal/day
\( Calories \) — Actual calorie intake in kcal/day

Explanation: The BMR formula estimates your basal metabolic rate, while the deficit calculation shows the difference between your energy expenditure and intake.

3. Importance of BMR and Calorie Deficit Calculation

Details: Understanding your BMR helps determine your basic calorie needs, while calculating calorie deficit is essential for effective weight management and achieving weight loss goals.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, TDEE in kcal/day, and daily calorie intake in kcal/day. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy calorie deficit for weight loss?
A: A deficit of 500-1000 kcal per day is generally recommended for safe and sustainable weight loss of 0.5-1 kg per week.

Q2: How accurate is the BMR calculation?
A: This formula provides a good estimate, but individual variations exist due to factors like muscle mass, genetics, and health conditions.

Q3: Should I eat below my BMR?
A: It's generally not recommended to consistently eat below your BMR as this can slow down your metabolism and affect basic bodily functions.

Q4: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or every few months to account for metabolic changes.

Q5: What factors affect TDEE?
A: TDEE is influenced by physical activity level, occupation, exercise routine, and non-exercise activity thermogenesis (NEAT).
