Healthy BMI range is between 18.5 - 24.9 for young people and adults with a healthy weight. BMI is the measure of human body fat based on weight and height. Though BMI does not have a perfect measure, it is calculated by dividing your weight (kilograms), by height^2 (meters). This is particularly the case when a doctor is assessing obesity and overweight at the population level.
Down at the personal level, there are no limitations because it can be affected by gender, age, ethnicity, and lifestyle. Besides, BMI does not differentiate between lean mass and fat mass. In fact, it does not even recognize fat distribution in the body.
You will need two standard measurements (weight) and height. To get these, you have to use a stadiometer and weighing scale.
Using a stadiometer and weighing scale, take the correct reading for height in (meters) and weight (kilograms). Then apply the formula for BMI given below.
BMI = mass (kg) / height^2 (meter)
Healthy Weight Range = BMI between 18.5 and 25.
The following classification is used to guide people know how far they have deviated from the healthy BMI range.
|Classification||BMI (kg/m^2)||Risk of co-morbidities (Health consequences)|
|Underweight||<18.50||Low (but possibly increased risk of other clinical problems)|
|Normal BMI range (Healthy Weight)||18.50 - 24.99||Average|
|Pre-obese||25.00 - 29.99||Increased|
|Obese class 1||30.00 - 34.99||Moderate|
|Obase class 2||35.00 - 39.99||Severe|
|Obese class 3||>40.00||Very severe|
The healthy BMI range is used mainly on young people and adult populations.
Pros of Healthy BMI range
- BMI healthy range is an easy to use measure whether in the field, clinical, or training purposes.
- Unlike other formulae, BMI factors additional factors such as current weight that affect an individual’s ideal body weight.
- Healthy BMI range is given in a complete tabular form that makes it easy to understand and apply at all levels.
Cons of healthy BMI range
- BMI still leaves out critical factors that affect an individual’s body weight such as body fat distribution.
After a long time of struggling with different formulae that only gave estimates within a very wide range, healthy BMI has finally provided a better solution. Though it still lacks in some ways because it does not factor all aspects of human weight such as lean mass and fat mass, it is the best among all other formulae.
