<h2>What Is BMI?</h2>
<p>Body Mass Index (BMI) is a simple measurement that uses your height and weight to estimate body fat. While it does not measure body fat directly, it is widely used by healthcare professionals as a quick screening tool.</p>
<h2>BMI Categories Explained</h2>
<ul>
<li><strong>Below 18.5</strong> — Underweight: May indicate malnutrition or underlying health conditions.</li>
<li><strong>18.5–24.9</strong> — Normal weight: Associated with the lowest health risks.</li>
<li><strong>25.0–29.9</strong> — Overweight: Increased risk of cardiovascular issues.</li>
<li><strong>30.0 and above</strong> — Obese: Significantly higher risk of diabetes, heart disease, and other conditions.</li>
</ul>
<h2>Limitations of BMI</h2>
<p>BMI has important limitations. It does not distinguish between muscle and fat. A bodybuilder with 8% body fat may have the same BMI as someone who is sedentary and overweight. BMI also does not account for age, gender, or ethnicity differences.</p>
