5. Risks & Detailed Limitations
Overweight Risks: Heart disease, Type 2 diabetes, high blood pressure, and stroke.
Underweight Risks: Weak immunity, bone loss (osteoporosis), and nutrient deficiencies.
- Muscle vs. Fat: BMI doesn't distinguish between muscle and fat. Athletes often have high BMI scores but low body fat.
- Fat Distribution: It doesn't show where fat is stored. "Belly fat" is more dangerous than fat stored in hips.
- Age & Bone Mass: It doesn't account for bone density or muscle loss in the elderly.
- Ethnic Differences: Studies show health risks can occur at a lower BMI for Asian populations (risk starts at 23 BMI).
6. Frequently Asked Questions (FAQs)
Q: Is BMI gender specific for adults?
A: No, the formula is the same for men and women. However, women naturally tend to have a slightly higher body fat percentage than men at the same BMI.
Q: Can BMI be used during pregnancy?
A: No. BMI is not accurate during pregnancy due to fetal growth and fluid changes.
Q: Why is my BMI different from my body fat percentage?
A: BMI is a weight-for-height ratio, while body fat percentage measures actual fat. You can have a "normal" BMI but high body fat (Skinny Fat).
Q: Weight vs BMI: Which is more important?
A: Waist circumference and body fat percentage are often more accurate health markers than BMI alone.
