1. What is BMR Calculator Maintenance?

The BMR (Basal Metabolic Rate) Calculator estimates your body's energy expenditure at rest, while Maintenance Calories represent the total calories needed to maintain your current weight based on your activity level.

2. How Does the Calculator Work?

The calculator uses the BMR equation:

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

And Maintenance Calories calculation:

\[ Maintenance = BMR \times activity\ factor \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation calculates your body's minimum energy requirements at complete rest, then adjusts for your daily activity level to determine maintenance calories.

3. Importance of BMR and Maintenance Calculation

Details: Understanding your BMR and maintenance calories is crucial for weight management, creating effective diet plans, and setting appropriate calorie goals for weight loss, maintenance, or gain.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at complete rest.

Q2: How accurate is this BMR calculation?
A: This formula provides a good estimate for most people, but individual variations in metabolism, body composition, and other factors can affect accuracy.

Q3: What do the different activity factors mean?
A: Sedentary (little exercise), Lightly active (light exercise 1-3 days/week), Moderately active (moderate exercise 3-5 days/week), Very active (hard exercise 6-7 days/week), Extra active (very hard exercise and physical job).

Q4: Should I use BMR or maintenance calories for weight loss?
A: For weight loss, create a calorie deficit from your maintenance calories, not your BMR, as maintenance calories already account for your daily activity.

Q5: How often should I recalculate my BMR and maintenance?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.
