1. What is the BMR Calculator?

The BMR (Basal Metabolic Rate) calculator estimates the number of calories your body needs to perform basic life-sustaining functions at rest. It provides an important baseline for determining daily calorie needs.

2. How Does the Calculator Work?

The calculator uses the BMR equation:

Where:

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

Explanation: This equation calculates the basal metabolic rate, which represents the minimum energy required to maintain vital body functions while at complete rest.

3. Importance of BMR Calculation

Details: Accurate BMR calculation is crucial for weight management, creating effective diet plans, and understanding individual metabolic needs for maintaining, losing, or gaining weight.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What factors affect BMR?
A: BMR is influenced by age, gender, weight, height, body composition, and genetic factors.

Q2: How does BMR differ from TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q3: Can BMR change over time?
A: Yes, BMR typically decreases with age and can change with weight loss/gain and changes in muscle mass.

Q4: How accurate is this BMR formula?
A: This formula provides a good estimate for most adults, but individual variations may exist due to metabolic differences.

Q5: Should I use BMR for weight loss planning?
A: BMR is a starting point for weight management, but you should also consider activity level and other factors for comprehensive planning.
