How To Get Bmi Number

This calculator should only be used past adults (pregnant or lactating women should not rely on these BMI readings), and no action should exist taken based on its values other than to consult a suitably qualified person such equally a doctor.

The figurer will give you an idea of how your weight compares to mutual values. Body Mass Index (or BMI) is calculated as your weight (in kilograms) divided by the square of your height (in metres) or BMI = Kg/M2.

Is Body Mass Index reliable?

Your BMI, or Body Mass Alphabetize, is a mensurate of your weight compared to your elevation. Accurate assessments of obesity are of import, as beingness overweight or obese significantly increases your risk of a diversity of medical weather condition including type 2 diabetes, heart disease and cancer. As levels of overweight or obesity increase, the spotlight has fallen on BMI and its shortcomings as a mensurate of ideal weight for individuals, rather than whole populations of people where 'averages' apply.

"Some people naturally have a larger frame than others. But this causes quite a minor variation in weight and is accounted for in the range of salubrious BMI. There is really no such matter as someone who is big-boned." Dr Jan Sambrook,How to lose weight in a healthy way

For almost adults, BMI gives a good estimate of your weight-related health risks. If your BMI is over 35, your weight is definitely putting your health at risk, regardless of the factors below. However, there are some situations where BMI may underestimate or overestimate these risks in the 25-35 BMI range. The main ones are:

Children

Your GP or health company tin propose on where your child sits on the 'centile charts' used to gauge healthy weights for children.

Pregnant women

Usual BMI estimates do non apply if you're pregnant.

If yous are very muscular

BMI assumes yous have an average corporeality of trunk fatty, including 'intra-abdominal fatty' – fatty deep inside your stomach cavity rather than nether your skin. Intra-abdominal fatty is much more than closely linked to risks of type two diabetes and heart illness than fatty under the pare.

If you are very muscular, your level of torso fat may be lower than predicted by your BMI. However, this merely applies to people who practise high levels of do – much more than average.

If you are of Asian origin

People of Asian origin are decumbent to accumulating intra-abdominal fat (fat deep inside your stomach crenel rather than under your pare) at a lower BMI than people of Caucasian origin. People with this pattern of weight gain are described as 'apples' rather than 'pears' from their body outline. This means their health risks outset to rise at a lower BMI, because intra-abdominal fat is directly linked to evolution of heart disease and type 2 diabetes.

The Globe Health Organisation has looked at the evidence and considering of the variability betwixt unlike Asian populations, it hasn't officially inverse the cut-off points. However, it does recommend that for public health purposes, some Asian groups should exist considered overweight if their BMI is 22-25, and obese with a BMI of 26-31.

Older people (over 65, maybe over 60)

Because musculus mass tends to drop and body fatty tends to rise in older people, BMI may non be an accurate reflector of body fat if y'all're over lx.

Alternative estimates of weight-related health risks

If you feel BMI may not accurately reflect whether yous are overweight or obese, measuring your abdominal circumference, waist-hip or waist-tiptop ratio may give you a more than realistic gauge.

Waist circumference

You mensurate your waist circumference half style betwixt the bottom of your ribcage and the summit of your hip bones, with the tape measure parallel to the flooring. You must be breathing out when y'all measure.

Male person

Increased wellness risk - ≥94cm
High health adventure - ≥102cm

Female

Increased health risk - ≥80cm
High health risk - ≥88cm

Waist to hip ratio

To check your waist to hip ratio, measure your waist circumference (as above), and your hip size at the widest part of your hips. Divide your intestinal circumference by your hip measurement to give a ratio.

In women, a waist to hip ratio greater than 0.85 is associated with greater than boilerplate take chances.
In men, a waist to hip ratio greater than i.00 is associated with greater than average risk.

Waist to height ratio

A recent study comparing BMI, waist circumference, waist to hip ratio and waist to height ratio plant that the most accurate way of predicting your whole-body fat level was waist-height ratio.

Mensurate your waist circumference as higher up and simply divide it by your pinnacle – adequately obviously both measurements should either be in majestic (inches) or metric (cm).

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

0.53 or more for men
0.54 or more for women

Abdominal obesity was defined past a waist-height ratio of 0.59 or more.
