1. What Is BMR For Weight Loss?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. Knowing your BMR is essential for effective weight loss planning as it helps determine your daily calorie needs.

2. How Does The Calculator Work?

The calculator uses the Mifflin-St Jeor equation for women:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years

Explanation: This equation estimates the calories your body burns at complete rest based on your body composition.

3. Importance Of BMR Calculation

Details: Accurate BMR estimation is crucial for creating effective weight loss plans, as it forms the foundation for determining your daily calorie needs when combined with activity level.

4. Using The Calculator

Tips: Enter your weight in kg, height in cm, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: How is BMR different from TDEE?
A: BMR is calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: How should I use BMR for weight loss?
A: Create a calorie deficit by consuming fewer calories than your TDEE (BMR multiplied by activity factor).

Q3: Does BMR change with weight loss?
A: Yes, as you lose weight your BMR decreases, requiring adjustment of your calorie intake for continued progress.

Q4: How accurate is this BMR calculation?
A: It provides a good estimate for most people, but individual variations in muscle mass and metabolism can affect actual BMR.

Q5: Should men use this calculator?
A: No, this uses the female equation. Men should use: BMR = 10 × weight + 6.25 × height - 5 × age + 5.
