1. What is the Schofield Equation Variant?

The Schofield equation variant estimates Basal Metabolic Rate (BMR) based on lean body mass. This specific formula provides a simplified approach to calculating daily calorie needs for weight maintenance at rest.

2. How Does the Calculator Work?

The calculator uses the Schofield equation variant:

Where:

• \( \text{Lean Body Mass} \) — Body weight minus fat mass (kg)
• 370 — Base metabolic constant
• 21.6 — Metabolic coefficient per kg of lean mass

Explanation: The equation estimates the minimum calories your body needs to perform basic life-sustaining functions while at complete rest.

3. Importance of BMR Calculation

Details: Accurate BMR estimation is crucial for determining daily calorie needs, creating effective diet plans, and managing weight goals (loss, maintenance, or gain).

4. Using the Calculator

Tips: Enter lean body mass in kilograms. Lean body mass can be estimated through body composition analysis or calculated as total weight minus fat mass.

5. Frequently Asked Questions (FAQ)

Q1: What is lean body mass?
A: Lean body mass includes muscles, bones, organs, and water - everything except body fat. It's a better indicator of metabolic rate than total body weight.

Q2: How accurate is this equation?
A: This variant provides a reasonable estimate for most adults, but individual variations in metabolism can affect accuracy by ±10-15%.

Q3: How do I calculate my total daily calorie needs?
A: Multiply your BMR by an activity factor (1.2 for sedentary, 1.375 for light activity, 1.55 for moderate, 1.725 for very active, 1.9 for extra active).

Q4: Should I use this for weight loss planning?
A: Yes, but consult with a healthcare professional for personalized advice, especially if you have medical conditions.

Q5: Are there limitations to this equation?
A: Less accurate for athletes with very high muscle mass, elderly individuals, or those with metabolic disorders.
