1. What is the Schofield Metabolic Rate Calculator?

Definition: This calculator estimates your Basal Metabolic Rate (BMR) using the Schofield equation, which is the number of calories your body needs at complete rest.

Purpose: It helps nutritionists, dietitians, and health-conscious individuals determine daily caloric needs for weight management.

2. How Does the Calculator Work?

The calculator uses the Schofield equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( k \) — Constant (gender and age specific)
• \( a \) — Weight coefficient (kcal/kg)
• \( W \) — Weight (kg)
• \( b \) — Height coefficient (kcal/cm)
• \( H \) — Height (cm)
• \( c \) — Age coefficient (kcal/year)
• \( A \) — Age (years)

Explanation: The formula accounts for gender, age, weight, and height to estimate the calories burned at rest.

3. Importance of BMR Calculation

Details: Knowing your BMR helps create personalized diet plans, whether for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Select your gender, enter your age in years, weight in kg, and height in cm. The calculator uses appropriate coefficients based on your gender and age group.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at rest, while Total Daily Energy Expenditure (TDEE) includes activity and is typically 1.2-2.5× BMR.

Q2: Why does gender affect BMR?
A: Men generally have more muscle mass and less body fat, resulting in higher BMR.

Q3: How accurate is the Schofield equation?
A: It's reasonably accurate for most people but may vary ±10% for individuals with atypical body compositions.

Q4: Should I use this if I'm under 18?
A: No, the calculator uses adult coefficients. Pediatric equations are different.

Q5: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg) or when entering a new age bracket.
