Body Mass Index (BMI) Calculator
The BMI calculator provides a calculation between your height and your weight, giving you an evaluation of your corpulence, followed by any possible related health risks. Your looks are one thing, and your health is another. So take a few minutes to calculate your BMI.

The BMI calculator was invented by doctors to evaluate health risks linked to excess weight. Simply knowing a person’s weight isn’t enough to diagnose obesity, under or overweight. It’s not at all the same thing to weigh in at 90kg if you are 150cm tall or if you are 190cm tall… BMI is calculated by dividing your weight in kg by your square height in cm. Taking data from a number of studies, different levels have been established and documented by WHO to evaluate zones of risk, notably regarding cardiovascular disease.
The BMI calculator is a reliable method for most adults between the ages of 20-60, with the exception of pregnant or breast-feeding women, endurance athletes or people with very developed muscles.
Calculate your Body Mass Index (BMI):
Your Body Mass Index is:
Your weight appears to be insufficient in relation to your height. This lack of weight could be the consequence of illness, psychological problems or could be itself, the source of other disorders, thereby creating a vicious circle. It would be worthwhile consulting a doctor to better understand possible impacts of such a weight insufficiency, and to find the causes. Your doctor could then suggest an adapted course of treatment.

Your weight is within the normal range for your height. A balanced diet, without an excess of fat and sugar, and regular physical exercise such as walking, swimming or cycling, will help you maintain your ideal weight.

Your weight appears moderately excessive in relation to your height. This extra weight could increase the risk of illness, particularly cardiovascular disorders and diabetes. The risk can increase if combined with other factors such as smoking tobacco, high blood pressure or cholesterol. A diet with less fat and sugar, and rich in fruit and vegetables, along with regular physical activity will no doubt allow you to return to your ideal weight. Your doctor is well placed to give you advice adapted to your weight loss objective.

Your weight is way too much in relation to your height. You are suffering from obesity, which means that you are exposed to a certain risk of contracting a number of disorders such as: cardiac problems (heart attacks); circulatory problems (stroke, embolism or deep vein thrombosis); or metabolic problems (diabetes). Obesity can also be the source of shortness of breath, fatigue, back or joint pain and psychological problems, all of which can seriously impact upon your daily activities. Luckily, even a moderate loss of weight (5-10 %) can have a positive effect on your health and mind, if of course you do not put the lost kilos back on.
To this aim, it would be wise to practice some kind of physical activity every day as well as reducing the fat and sugar components of your diet. In any case, a consultation with your doctor is a, absolute must, so that he can do a complete health check up and, together with you, think about suitable weight loss methods along with any other necessary treatments. Patient support groups can also provide help and advice as well as precious psychological support.

What your BMI score means
BMI categories are set according to criteria defined by the World Health Organisation (WHO) as follows:
Attention, this classification is statistically calculated and does not necessarily apply to all adults across all countries, as well as for sports people and seniors. Speak with your GP if you have any doubts or questions.
BMI in the UK
Taking into consideration the BMI categories, 28% of UK adults were overweight in 2006 and 24% were obese, with a greater proportion of men overweight than women (43% vs. 32%). However, with regard to severe obesity, there was a greater prevalence amongst women (3% vs. 1% in men).
These figures mean that as of 2006 some 52% of the UK population were in some way overweight and the trend continues to rise since.
BMI and waist circumference, getting a more accurate weight analysis
Due to the limitation of the Body Mass Index, in that it is not possible to take muscle mass or distribution of fat into account, another measure is used to better identify those at risk of health problems due to excess weight. This measure is known as the waist circumference. Many studies have shown that people who, in addition to a BMI score between 25-35, have an increased waist circumference also have increased risk factors for developing long-term health problems such as heart disease, Type 2 diabetes, osteoarthritis and some cancers.
A raised waist circumference measure is simple to define as:
- •A waist circumference over 102 cm in men
- •A waist circumference over 88 cm in women
If your BMI is out of the normal weight range, and particularly if you also have a raised waist circumference, you should consult your GP or nutritionist for a check up.
