What is Basal Metabolic Rate (BMR) and what does it measure?

BMR is the baseline energy expenditure in calories required to maintain involuntary life-sustaining physiological functions (breathing, cardiac pumping, cell repair) at rest.

Why is the Mifflin-St Jeor equation preferred over older formulas?

Clinical validation studies show Mifflin-St Jeor is accurate within 10% of indirect calorimetry, avoiding the 5-15% calorie overestimation common in older 1919 Harris-Benedict charts.

Why should you NEVER eat below your calculated BMR floor?

Eating below BMR triggers starvation response, suppresses thyroid hormones (T3), slows resting metabolism permanently, and induces muscle wasting and nutrient deficiencies.

How does thyroid health affect a person's metabolic rate?

Hypothyroidism slows BMR, causing fatigue and weight gain despite modest eating. Hyperthyroidism accelerates BMR, causing rapid weight loss and cardiac strain.

When should people in Khulna seek metabolic testing with a specialist?

If you struggle to lose weight despite a verified calorie deficit, or experience chronic cold intolerance and exhaustion, consult a Khulna endocrinologist.
