# What Is Body Mass Index?

INTRODUCTION

More than 60% of the world struggles with weight loss. They want a way to better their lives, but it’s tough to find a real weight loss program that will deliver results. Therefore, the BMI (Body Mass Index) calculator was founded to help individuals maintain a healthy life. So what exactly is a BMI Calculator?

## What is a BMI Calculator?

A BMI Calculator is a tool used to determine the Body Mass Index (BMI) of an individual. The equation is simple.

BMI = (Weight in lbs. * 703) / (Height in Inches) ^2

Example: If a person weighs 220 lbs. and is 72 inches tall then it would be as follows: (220 * 703) / (72)^2…….(154660) / (5184)….which equals 29.8. That person would have a BMI of 29.8.

One of the most common ways to determine whether or not you are overweight is to use a BMI calculator. Most people would have come across these, although they may not know exactly what they are or how they work. It is important that you understand what you are being told when you use one of these tools so that you can interpret the results correctly.

A BMI calculator is simply a computer program that allows you to calculate your Body Mass Index. This of course raises the question of what is your Body Mass Index. It is really just a quick and easy way to determine if you are overweight or not based on your height and your weight. The reason that this is used instead of just your weight is that the difference between what is considered overweight for a person who is five feet tall is not the same as it is for a person who is six feet tall.

Using a BMI calculator is pretty easy; all you really have to know is your weight in pounds and your height in inches. You will enter that number into the calculator and be given your results. The actual formula is pretty simple if you want to work it out yourself you can go online and find it but there are so many free BMI calculators that it is not really worth the effort to do the math yourself.

The results that you will get will be a number that ranges from about zero to fifty, it may be a bit higher if you are significantly overweight but most people will fall in the twenty to thirty range. Anything over twenty five is actually considered to be overweight so keep that in mind. All BMI calculators have charts that will help you to interpret your results.

Body Mass Index, or BMI, is used as the standard of measuring a person’s risk for developing health problems. Based on given results, a person may need further health screenings to check for potentially life-threatening conditions. When calculating BMI, a person’s height and weight are tracked on a universally-accepted, graph chart. This leads to a classification ranging from starvation to morbidly obese. While height and weight are analyzed, Body Mass Index does not disclose a person’s actual percentage of body fat. The goal of using a BMI calculation chart is to give a physician an idea of someone’s body mass index classification score and if necessary, to screen for possible present and future health problems.

Because a body mass number range provides an indicator of how much someone should weigh, many people have the perception that a lower BMI is better. This is only partially true as overweight, obese and morbidly obese people should set goals to enter into the normal category, which is classified as a range of 18.5 to 25. However, having a BMI lower than 18.5 is unhealthy and classifies persons either into the underweight or starvation categories. This could indicate that medical conditions such as anorexia, malnutrition or absorption deficiencies may be present and should be immediately addressed by a qualified physician.

On the opposite end of the spectrum, classifications from overweight to morbidly obese may indicate immediate health issues. Being overweight is having a BMI ranging from 26 to 30; obese ranges from 31-40 and morbidly obese is any body mass index number greater than 40.

It is important to know there are different BMI charts for adults and children. In adults, Body Mass Index is calculated based on height and weight, whereas children’s BMI is calculated based on age and gender. Children’s body mass index charts allows for the comparison of each child against his or her peers. The goal is to be as close to the 50 percent range as possible, with extreme deviations requiring immediate physician attention.

No matter what age, people with a high BMI may be endangering themselves. A body mass index in the overweight, obese or morbidly obese categories may be a warning that diabetes, heart disease, high blood pressure, sleep disorders, joint stress or other issues may be present. If not addressed and rectified, continued obesity may lead to early mortality. Without losing muscle mass, the only way to obtain a lower body mass index score is to lose weight.

## BMI CHART

Our health depends on good nutrition, daily activity as well as cheerful state of mind. However, it is essential that you have a precise picture of your overall health so that you can keep a good track on your body fat and its effects. In this scenario, a BMI chart comes in handy. BMI helps in determining your obesity scale. This chart will keep a plot on your weight and height to get your approximate Body Mass Index.

It is difficult to live a normal life if you are overweight. Today, people are so engrossed in earning money that they do not get time to keep a check on their eating habits, and this leads to increase in their cholesterol level. Moreover, it also gives rise to certain life threatening diseases like heart attack, stroke and diabetes. To find out where you exactly stand in this obesity scale, Body Mass Index chart plays a significant role.

Usually people with heavy weight have BMI between 25 and 29.9, whereas the underweight people have BMI somewhere around 18.5. Once you are aware of the BMI, you can change your lifestyle into a healthy one so as to ensure good health.

BMI chart is available for both the sexes–men as well as women. It is a reflection of a state of the body composition. People who are either overweight or underweight can take benefits of these charts so that your doctor can give you the right advice and guidance to come to a normal level.

Finally you have the extremely obese lot.

When you know that you are obese, you must see your doctor and tell him what you have observed.

After examining you, if he finds that you have any ailments such as high blood pressure, high cholesterol or diabetes he will first treat you with appropriate medication.
