📖 Why These Metrics Matter
BMI is a screening tool for weight categories. BMR tells you calories burned at rest. Body fat percentage gives a clearer picture of fitness than weight alone. Waist-to-height ratio helps assess abdominal fat risk.
Use these numbers as a starting point for conversations with healthcare professionals.
❓ Frequently Asked Questions
Is BMI accurate for everyone? BMI doesn't account for muscle mass. Athletes may have high BMI but low body fat.
How much water should I drink? The 33 ml/kg guideline is a baseline. Adjust for activity level and climate.
What's a healthy waist-to-height ratio? Aim for less than 0.5 to reduce health risks.
