BMI CALCULATOR VISUAL

Although body measurements can provide a decent assessment of health state and chronic disease risk factors, they do not establish health status. Health is a subjective concept; each individual is unique. Depending on our surroundings, lifestyle, and family history, we are exposed to various risk factors. Nonetheless, the body mass index, waist circumference, and waist-to-hip ratio are the three most regularly used metrics to evaluate health status.

A person’s height and weight are used to compute their BMI, which can reveal their fat content. However, because BMI does not take into consideration muscle mass, top athletes may have high BMI scores.

BMI is commonly employed as a health indicator since the lower or higher the BMI, the higher the health risk depending on the expected quantity of body fat. For women, a healthy BMI would be in the usual range of 18.5 to 24.9. According to the Arizona Department of Health Services, 57% of Arizona women have a BMI of 25 or higher, indicating that they are overweight or obese.

BMI Formula

1. Metric Calculations

BMI is measured in kilograms per square meter (kg/m2 ) and is always expressed in kilograms per square meter(kg/m2 ). kg/m2 refers to a person’s weight in kilograms (KG) and height in meters (CM). To determine an adult’s BMI, follow these steps:

  • Subtract their weight in kilograms (kg) from their height in meters squared (m2).
  • Most people measure their height in centimeters (cm), and multiply their height in centimeters by 100 to get their height in meters.
BMI(kg/m2) = mass(kg) / height2(m)

2. Imperial Calculations

The formula is BMI = lbs x 703/in2 in imperial units. To put it another way, multiply 703 by a person’s weight in pounds (lbs). Then multiply by their squared height in inches (in)2.

  • Convert your weight from pounds to kilograms.
  • Your weight (in pounds) ÷ 2.2 = your weight (in kilograms). For example, 132 pounds ÷ 2.2 kilograms = 60 kilograms.
  • Convert your height from inches to meters.
  • Your height (in inches) ÷ 39.37 = your height (in meters). For example, 65 inches ÷ 39.37 meters = 1.65 meters.
  • Calculate your Body Mass Index.
BMI(kg/m2) = mass(lb) / height2(in) × 703

BMI Score Explanation

BMI of less than 18.5BMI of 18.5–24.9BMI of 25–29.9BMI of over 30
If your BMI is less than 18.5, you are underweight and may need to gain some weight. It is suggested that you seek guidance from your doctor or a dietician.With a BMI of 18.5-24.9, you are at a healthy weight for your height. Maintaining a healthy weight reduces your chances of getting significant health conditions.You are mildly overweight if your BMI is between 25 and 29.9. For health reasons, you may be advised to lose weight. It is suggested that you seek guidance from your doctor or a dietician.You are severely overweight if your BMI is greater than 30. If you do not lose weight, your health may be jeopardized. It is suggested that you seek guidance from your doctor or a dietician.

Is the BMI a trustworthy metric?

Your BMI, or Body Mass Index, is a calculation that compares your weight to your height. Obesity must be accurately assessed because being overweight or obese raises your risk of a number of medical diseases, including type 2 diabetes, heart disease, and cancer. As the number of people who are overweight or obese rises, the focus has shifted to BMI and its flaws as a measure of ideal weight for individuals rather than entire populations where ‘averages’ apply.

“Some persons have a larger frame by nature than others. However, this results in a minor weight change that is accounted for within the appropriate BMI range. There is no such thing as a large-boned individual.” Jan Sambrook, Ph.D. What is the best way to reduce weight in a healthy way?

BMI is an excellent indicator of weight-related health concerns for most people. Regardless of the variables below, if your BMI is over 35, your weight is putting your health at risk. However, in the 25-35 BMI range, BMI may underestimate or exaggerate these hazards in specific cases. The most important are:

Children

Your doctor or health visitor can tell you where your child falls on the ‘centile charts,’ which are used to determine children’s healthy weights.

Pregnant women

When you’re pregnant, standard BMI calculations don’t apply.

Muscular Person

BMI assumes you have an average amount of body fat, which includes ‘intra-abdominal fat,’ which is fat that is deep inside your stomach cavity rather than beneath your skin. Intra-abdominal fat is associated with a higher risk of type 2 diabetes and heart disease than fat under the skin.

If you’re exceptionally muscular, your body fat percentage may be lower than your BMI suggests. This, however, only applies to persons who exercise at a high level – far more than the ordinary person.

Asian origin People

People of Asian ancestry have a lower BMI and are more likely to accumulate intra-abdominal fat (fat deep inside your stomach cavity rather than under your skin) than people of Caucasian ancestry. People that gain weight in this way are referred to as ‘apples’ rather than ‘pears’ because of their body shape. Because intra-abdominal obesity is directly linked to the development of heart disease and type 2 diabetes, their health risks begin to rise at a lower BMI.

The World Health Organization reviewed the evidence and decided not to adjust the cut-off points because of the heterogeneity among Asian populations. However, for public health concerns, it is recommended that some Asian groups be classified as overweight if their BMI is 22-25, and obese if their BMI is 26-31.

Older people (over 65, possibly over 60)

Because muscle mass declines and body fat increases as people age, BMI may not be an appropriate indicator of body fat in persons over 60.

Alternative estimates of weight-related health risks

If you believe your BMI does not adequately reflect whether you are overweight or obese, you can get a more accurate assessment by measuring your abdominal circumference, waist-hip, or waist-height ratio.

Waist circumference

With the tape measure parallel to the floor, measure your waist circumference halfway between the bottom of your ribs and the top of your hip bones. When you measure, you must be exhaling.

Male

Increased health risk – ≥94cm

High health risk – ≥102cm

Female

Increased health risk – ≥80cm

High health risk – ≥88cm

Hip-to-waist ratio

Measure your waist circumference (as above) and hip size at the broadest portion of your hips to determine your waist to hip ratio. To get a ratio, divide your belly circumference by your hip measurement.

A waist-to-hip ratio of more than 0.85 is linked to a higher-than-average risk in women.

A waist-to-hip ratio of more than 1.00 in men is connected with a higher-than-average risk.

Height-to-waist ratio

The waist-height ratio was found to be the most accurate way of predicting your whole-body fat level in a recent study comparing BMI, waist circumference, waist-to-hip ratio, and waist-to-height ratio.

As before, measure your waist circumference and divide it by your height — both measures should, of course, be in imperial (inches) or metric (cm) (cm).

Whole body obesity is defined by a waist-height ratio of:

0.53 or more for men

0.54 or more for women

A waist-to-height ratio of 0.59 or more was used to identify abdominal obesity.
