Common Questions
Learn more about BMI and healthy weight management.
How accurate is BMI?
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat mass, so athletes may have a high BMI despite being healthy. It's best used alongside other health indicators.
What's a healthy rate of weight loss?
A safe and sustainable rate is 0.5-1 kg (1-2 lbs) per week. Rapid weight loss can lead to muscle loss, nutritional deficiencies, and other health issues.
Does BMI differ by age?
Yes, BMI interpretation can vary with age. For children and teens, BMI is age and sex-specific. For adults over 65, a slightly higher BMI may be protective.
Should I rely only on BMI?
No. Consider other factors like waist circumference, body fat percentage, blood pressure, and blood sugar levels for a complete health picture.
