Frequently Asked Questions

What is a healthy BMI range?

A BMI between 18.5 and 24.9 is considered healthy/normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is classified as obese. However, BMI doesn't account for muscle mass, bone density, or body composition.

Is BMI accurate for athletes?

BMI may overestimate body fat for athletes and muscular individuals since it doesn't distinguish between muscle and fat mass. Athletes should consider additional metrics like body fat percentage for a more accurate assessment.

How often should I check my BMI?

Checking your BMI once a month is sufficient for tracking trends. Remember that BMI is just one health indicator - consult healthcare professionals for comprehensive health assessments.
