1. What is the Mifflin-St Jeor Equation?

The Mifflin-St Jeor equation is considered one of the most accurate formulas for calculating Basal Metabolic Rate (BMR). For obese individuals, we apply an adjustment factor to account for metabolic adaptations that occur with obesity.

2. How Does the Calculator Work?

The calculator uses the adjusted Mifflin-St Jeor equation:

\[ BMR = (10 \times weight + 6.25 \times height - 5 \times age + s) \times 0.75 \]

Where:

\( weight \) — Body weight in kilograms
\( height \) — Height in centimeters
\( age \) — Age in years
\( s \) — +5 for males, -161 for females
\( 0.75 \) — Obesity adjustment factor (75% of calculated BMR)

Explanation: The equation calculates adjusted BMR which is then multiplied by an activity factor to determine daily calorie needs for weight management in obesity.

3. Importance of Calorie Calculation for Obesity

Details: Accurate calorie estimation is crucial for developing effective weight management strategies for obese individuals. The adjusted calculation accounts for metabolic changes associated with obesity.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why use an adjustment factor for obesity?
A: Obese individuals often have metabolic adaptations that lower their actual energy expenditure compared to predicted values from standard equations.

Q2: Is this calculator suitable for weight loss?
A: Yes, the calculated value represents maintenance calories. For weight loss, subtract 500-1000 calories depending on desired weight loss rate.

Q3: How accurate is this calculation?
A: While more accurate than unadjusted equations, individual variations exist. Consider this a starting point and adjust based on actual results.

Q4: Should I consult a healthcare provider?
A: Yes, especially if you have medical conditions. This calculator provides general guidance, not medical advice.

Q5: How often should I recalculate my needs?
A: Recalculate every 10-15 kg of weight loss, as calorie needs decrease with weight loss.
