Body Mass Index (BMI) is a ratio of your weight and height, and depending on the value one can be categorised as underweight, ideal, overweight or obese. Usually, BMI from 18.5 up to 25 is considered to be healthy.

Using a BMI Chart and calculator, one can easily determine the BMI.

BMI (along with other health indicators) is widely use by doctors, fitness instructors and nutritionists to assess the current health status and related health risks of a person.

Not sure if you are on the thinner side or slightly on the fatty side?

Determine your BMI with the calculator below.

What Is BMI?

BMI stands for Body Mass Index. It is basically a chart that helps you determine your body weight relative to your height.

A Body mass index chart tells you if you have the right amount of fat, or are you over-weight (or underweight).

The BMI chart is applicable for adults aged 20 to 65. It does not apply to infants, pregnant or brast-feeding women and adult over 65 years of age.

The Body Mass Index (BMI) formula was developed by Belgium statistician Adolphe Quetelet, and is also known as the Quetelet Index.

The BMI chart and the BMI calculator below provide a numeric measure of your “thinness” or “fatness”. Use it to determine your Body Mass Index.

BMI between 20 and 22: Ideal, healthy amount of body fat, makes you look attractive.
BMI between 22 and 25: Acceptable range, considered to be healthy.
BMI between 25 and 30: On the “Hefty” side, time to lower your weight, through diet and exercise.
BMI over 30: Unhealthy condition, likely to have heart disease, diabetes, high blood pressure, and more. time to get serious about losing weight.

Here’s a body composition chart that is usually taken at a gym on the first day when you join. After a couple of months, this chart is again generated to see how your body has changed in those few months.

As you can see, besides BMI, the chart shows various other parameters like BMR (Basal Metabolic Rate), WHR (Wait to Hip Ratio), PBF (Percentage Body Fat), Proteins, TBW (total Body Water), SMM (Skeletal Muscle Mass). You have to provide yourage, weight, and height.

Limitations of a BMI Chart

There a couple of limitations though with using a BMI chart!

It does not tell you where fat is located
Does not distinguish between fat mass and muscle mass

The obvious problem with the second point is that if you have a lot of muscle mass, your BMI could be calculated in the over-weight range.

But in this case you have more of muscles…so nothing to worry about!

If your BMI is high and you do not have a pot belly, then you are probably alright.

Who Should Use BMI Charts?

BMI charts are usually used by obese individuals, where it is difficult to determine your body composition with calipers.

BMI for Seniors / Over 65

The Body Mass Index (BMI) used for older people (above 65) is different than the general population’s normal ranges, says a report.

Doctors recommend that instead of focusing on weight loss, older people should have more of a balanced diet, eat when hungry and keep active.

“It is time to reassess the healthy weight guidelines for older people. Our results showed that those over the age of 65 with a BMI of between 23 and 33 lived longer, indicating that the ideal body weight for older people is significantly higher than the recommended 18.5-25 ‘normal’ healthy weight range,” Caryl Nowson, a professor of nutrition and aging at Deakin University.
