Resting Calories Burned Calculator To Lose Weight

Mifflin-St Jeor Equation:

\[ RMR = 10 \times weight + 6.25 \times height - 5 \times age + 5 \text{ (men)} \] \[ RMR = 10 \times weight + 6.25 \times height - 5 \times age - 161 \text{ (women)} \]

1. What Is The Mifflin-St Jeor Equation?

The Mifflin-St Jeor equation is considered one of the most accurate formulas for calculating resting metabolic rate (RMR), which represents the number of calories your body burns at rest to maintain basic physiological functions.

2. How Does The Calculator Work?

The calculator uses the Mifflin-St Jeor equation:

\[ RMR = 10 \times weight + 6.25 \times height - 5 \times age + 5 \text{ (men)} \] \[ RMR = 10 \times weight + 6.25 \times height - 5 \times age - 161 \text{ (women)} \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
+5 — Added for men
-161 — Subtracted for women

Explanation: This equation accounts for differences in metabolism based on gender, age, height, and weight to provide an accurate estimate of resting calorie expenditure.

3. Importance Of RMR Calculation For Weight Loss

Details: Knowing your RMR is essential for effective weight management. It helps determine your baseline calorie needs, allowing you to create an appropriate calorie deficit for weight loss while maintaining adequate nutrition.

4. Using The Calculator

Tips: Enter your weight in kilograms, height in centimeters, age in years, and select your gender. For accurate results, use precise measurements and consider measuring in the morning before eating or drinking.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the Mifflin-St Jeor equation?
A: It's considered one of the most accurate RMR prediction equations, with an accuracy of about ±10% for most populations.

Q2: Should I eat below my RMR to lose weight?
A: No, your RMR represents the minimum calories needed for basic bodily functions. For healthy weight loss, create a deficit from your total daily energy expenditure (TDEE), which includes activity calories.

Q3: How often should I recalculate my RMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or annually as you age, since metabolism changes with body composition and age.

Q4: Does muscle mass affect RMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Those with more muscle mass typically have a higher RMR.

Q5: Can medical conditions affect RMR?
A: Yes, thyroid disorders, hormonal imbalances, and certain medications can significantly impact metabolic rate. Consult a healthcare provider if you suspect metabolic issues.
