Frequently Asked Questions
What is the correct weight and height for age?
Ideal weight varies by height more than age for adults. For children, growth charts are used. Adults should focus on height-based ranges rather than age.
How do you calculate your ideal body weight?
Ideal body weight is calculated using height and gender-based formulas. The Devine formula is most common: 50kg + 2.3kg per inch over 5ft for men, 45.5kg + 2.3kg per inch over 5ft for women.
Is 70 kg a good weight?
70kg can be healthy depending on height. A 175cm person has healthy BMI at 70kg, but someone shorter might be overweight. Always consider height and body composition.
What is the ideal weight for an older woman?
Older adults may have slightly higher healthy weights due to muscle changes. Focus on maintaining muscle mass and overall health rather than strict numbers. Consult a healthcare provider.
Which formula is best for ideal weight?
Different formulas serve different purposes. Devine is commonly used for medication dosing, Hamwi for nutrition, BMI for population studies. Use multiple for best understanding.
Why don't doctors use BMI anymore?
BMI is still used but with limitations. It doesn't distinguish muscle from fat, doesn't account for age/gender differences. It's a screening tool, not diagnostic.
