1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. It represents the minimum energy required to keep your body functioning, including breathing, circulation, and cell production.

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: The equation accounts for the energy needed to maintain basic body functions based on your body size and age.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in creating personalized diet plans for weight loss, maintenance, or gain. It's the foundation for calculating your total daily energy expenditure (TDEE).

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. For accurate results, measure your weight and height in the morning before eating.

5. Frequently Asked Questions (FAQ)

Q1: How does BMR differ for men and women?
A: Women generally have a lower BMR than men of the same size due to differences in body composition (higher fat percentage).

Q2: What factors affect BMR?
A: Muscle mass, age, genetics, body size, hormonal status, and environmental temperature can all influence BMR.

Q3: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (±5 kg) or every 6 months as you age.

Q4: Does pregnancy affect BMR?
A: Yes, BMR increases during pregnancy due to the energy demands of fetal growth and maternal tissue changes.

Q5: How can I increase my BMR?
A: Building muscle through strength training can increase your BMR as muscle tissue burns more calories at rest than fat tissue.
