It is a simple calculation that can help assess whether a person is underweight, normal weight, overweight, or obese.<\/p>\n\n\n\n<p>The formula uses either the metric system (kilograms and meters) or the imperial system (pounds and inches). For metric: divide weight in kilograms by the square of height in meters. For imperial: multiply the weight in pounds by 703 and divide by the square of the height in inches.<\/p>\n\n\n\n<p>Each result is a number that falls into a classification:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Underweight<\/strong>: BMI less than 18.5<\/li>\n\n\n\n<li><strong>Normal weight<\/strong>: 18.5 \u2013 24.9<\/li>\n\n\n\n<li><strong>Overweight<\/strong>: 25 \u2013 29.9<\/li>\n\n\n\n<li><strong>Obese<\/strong>: 30 or greater<\/li>\n<\/ul>\n\n\n\n<p>Let\u2019s analyze the examples:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>first person<\/strong> has a BMI of <strong>25.8<\/strong>, placing them slightly into the <strong>overweight<\/strong> category.<\/li>\n\n\n\n<li>The <strong>second person\u2019s<\/strong> BMI is <strong>22.0<\/strong>, which is considered <strong>normal<\/strong>.<\/li>\n\n\n\n<li>The <strong>third person<\/strong>, with a BMI of <strong>22.8<\/strong>, also falls within the <strong>normal<\/strong> range.<\/li>\n\n\n\n<li>The <strong>fourth individual<\/strong> has a BMI of <strong>31.0<\/strong>, which indicates <strong>obesity<\/strong>.<\/li>\n\n\n\n<li>The <strong>last individual\u2019s<\/strong> BMI is <strong>18.5<\/strong>, right on the edge between <strong>underweight and normal<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>BMI is a useful population-level tool, but it has limitations. It does not account for muscle mass, bone density, overall body composition, or distribution of fat. For example, a highly muscular person might have a high BMI but low body fat. Still, it remains a quick and cost-effective screening method to assess weight status and associated health risks<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Weight =68.1kg, Height =162.6cm: BMI= Weight =124 lbs, Height =63 inches: BMI= Weight =76.4kg, Height =182.9cm: BMI= Weight =216lbs, Height =177.8cm: BMI= Weight =108lbs, Height =162.6cm: BMI= Please help and show work.
