Healthy BMI FAQ
Is BMI the same for men and women?
The BMI ranges are the same for both genders, but body composition differences mean women naturally have higher body fat percentages than men.
Can athletes have a healthy BMI above 25?
Yes, athletes and muscular individuals often have higher BMI due to muscle mass rather than fat. BMI should be interpreted alongside other health indicators.
How often should I check my BMI?
Check BMI monthly when actively working on weight goals, or quarterly for general health monitoring. Focus on trends rather than single measurements.
Is BMI accurate for everyone?
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat, and may not be ideal for certain populations like athletes or the elderly.
What if my BMI is outside the healthy range?
If your BMI is outside the healthy range, consult a healthcare professional. They can help determine if lifestyle changes or medical intervention are needed.
