BMI: The body mass index (BMI)
The body mass index (BMI) is the individual’s body mass index divided by squares of the height in meters. BMI is an inexpensive and easy screening method for weight category–underweight, healthy weight, overweight, and obesity. bmi chart women discuss below
BMI is not a measure of the body’s fat level directly, but BMI is somewhat correlated with other measurements of fat in the body 1,2,3. Additionally, BMI is believed to be as closely correlated with different metabolic and health outcomes as do the more precise measures of body fat 5,6,7,8,9.
BMI of an individual is calculated through using mathematical formula. It is also possible to estimate by using tables that can relate the height in inches and weight in pounds in order to determine BMI. There are a variety of calculators on web sites to aid in calculating BMI in addition.
The formula is BMI = (Weight in kilograms) divided by (Height in meters squared) OR W/H^2
A typical BMI score ranges in the range of 18.5 between 18.5 and 24.9. This means that the person is in of the weight-to-height range that is normal for his height. A BMI chart can be used to classify an individual as being normal, underweight, overweight or obese.
Other indicators of a fit body
BMI is an effective tool, but it doesn’t determine if a person’s weight is composed of fat or muscle.
For example, an individual who has a significant amount of muscle tissue could have an elevated BMI than someone who is not active. However, this doesn’t suggest that the athlete is unhealthy or overweight.
Additionally, cardiovascular diseases or high blood pressure is more likely develop when people have extra fat, also known as visceral fat around their middle , but not their hips.
Other indicators of body size are the waist-to-hip ratio, waist-to-height ratio and body composition which measure body fat as well as the mass of lean muscle. These measurement methods are more focused on the amount of fat an individual has and how it is distributed across the body.
Along with BMI These additional measures will help identify more accurately the health risks that come with a person’s weight.
How to determine body fat percentage
The most popular method of determining the percentage of body fat is using the measurement of a skinfold that uses calipers specially designed to press the skin.
The healthcare professional will take measurements of tissues on the thigh or abdomen and chest (for males)) or the upper arm (for women). The procedures provide a precise reading of around 3.5 percent, as per ACE.
Other methods include trusted Source:
- measurement of body fat in hydrostatic fluids the amount of body fat in the water, also known as “underwater weighting”
- air densitometry, which is a method to measure the displacement of air
- Dual energy X-ray absorptiometry (DXA)
- Bioelectrical impedance analysis
None of these will give 100% accuracy however, these estimates can provide an acceptable estimation.
A number of gyms and doctors’ offices have equipment to determine the body fat percentage of a person.

Once someone knows their BMI, they can find out where their measurement falls in the following standard weight categories from the National Heart, Lung, and Blood InstituteTrusted Source
|Underweight women||Below 18.5|
|Healthy weight women||18.5–24.9|
|Obese women||30.0 and higher|
