BMI - A Better Measure of Body Fat

BMI is a formula that factors in height and weight to produce a number designed to estimate the presence of excess body fat. BMI measurement is a better appraisal of excess fat, as opposed to body weight alone, since it relates height to weight. For example, knowing a person weighs 200 lbs isn’t sufficient data to appraise whether they are overweight. Factoring in a person’s height helps put their body weight into perspective: An individual who is 6-foot and 200 lbs may not be carrying excess body weight, while another person who is 5-foot-8 and 200 pounds is more than in all likelihood to carry surplus body fat.

BMI and Body Fat

High BMI numbers are affiliated with enhanced risks of disease and death. High BMI numbers are affiliated with diseases such as type 2 diabetes, cardiovascular disease, and some cancers. Extensive research has discovered that the lowest and highest BMIs are affiliated with the worst health risks. So BMI numbers are classified into categories meant to reflect the grade of jeopardy a person faces.

Those people with the lowest risks of disease seem to land in the 18.5 to 24.9 BMI range, so they are believed to be “normal.”

A BMI of 25 seems to be the marker where disease risk significantly step-up, and a BMI of 30 confers even greater health hazards. So these rates are classed into “overweight” and “obese” categories.

BMIs 40 and above are linked up to even bigger hazards of certain health hazards. The “underweight” category is included because being overly thin is also related with raised health risks.

BMI Categories - Overweight and Obese

Underweight         <18.5
Normal                 18.5 - 24.9
Overweight           25.0 - 29.9
Obesity                30.0 - 39.9
Extreme Obesity    40+

Being diagnosed with a BMI of 30 or more signifies that you are fat. A BMI of 25+ signifies that you are heavy, and while a heavier individual ordinarily has too much fat, this is not inevitably true.

Heaviness isn't necessarily a result of bearing too much body fat. Muscular people can be excessively heavy. Muscular people may have a very low percentage of body fat, despite weighing more than expected on a scale. So their BMI total might undependably indicate they hold more body fat than they do. Athletic people, often have higher BMIs. But since they are fit and lean, they are not inevitably at enhanced danger of certain health risks just because they sustain a massive BMI.

In certain instances BMI is not a trusted indication of body fat.

Elderly people may carry more body fat and less muscle, but their BMI amount may live on the low end of the BMI scale, indicating that they carry less body fat than they do.

Individuals under 5 ft may too have high BMI figures that do not accurately reflect their level of fat. People who are recovering from illness or on medicines that have abnormal quantities of edema, or swelling in the body, may weigh to a greater extent from unnecessary fluid collection. In this example, a ample BMI amount may not signal the absence or presence of body fat.

As a statistical measuring device utilizing thousands of examples, BMI is usable when running with research data points to approximate the prevalence of the overweight and obese and interrelated disease risks. For the individual, BMI is a useful way to monitor weight changes over time.

Because BMI does not directly measure body fat, or where body fat is dispersed, it may not be the best method of evaluating personal stages of fatness and how it interrelates to health risks. Waistline, and other factors should be looked at when measuring a person’s overall health endangerments.

How to Learn Your BMI

Get your BMI number from a lab. Some lab measuring equipment such as dual-energy X-ray absorptiometry, underwater scales and the Bod Pod measure body fat directly. There are other ways (although less reliable) to meter body fat. Including skin fold testing or using a commercial body fat scale, some gyms offer these body fat testing services.

The BMI test is a better means to ascertain if you have unnecessary body fat. BMI links height to weight and is a better judgment of fatness, as opposed to using body weight alone.

Scientists have ascertained that the lowest and highest BMIs are related with the highest health perils such  as cancer, cardiovascular disease, and type 2 diabetes.

BMI numbers are classified into categories intended to interpret the stage of jeopardy a person faces. A BMI of 25 seems to be the doorway where health hazard really steps-up, and a BMI of 30 implies even greater health stakes. Extremely high BMIs (40+) are matched to even greater dangers of certain health risks. The BMI “underweight” class is part of the chart because being overly twiggy is also correlated with increased wellness dangers. Getting your BMI evaluated may be an unreasonable or pricey suggestion for some people, but there are alternatives such as skin fold measuring, that are not as exact, but less expensive or free and are on hand at local health clubs.
