The range of normal BMI and its calculation


normal bmi

There is no definitive answer to this question. The Body Mass Index (BMI) range considered to be “normal” varies from person to person and even changes over time for the same person. However, according to the World Health Organisation (WHO), a BMI within the range of 18.5 to 24.9 is generally considered to be healthy. A BMI below 18.5 is classified as underweight, while a BMI above 25 is classified as overweight. Obesity is defined as having a BMI of 30 or higher.

BMI can be misleading, however, as it does not take into account a person’s muscle mass or body composition. So someone who is extremely muscular could have a high BMI even if they are not overweight.

Just to give you an idea, the normal BMI range goes from 18.5 to 24.9 by WHO criteria. This is the middle of the safe zone which still has health benefits.

Proper Weight And Normal BMI

A BMI below 18.5 is classified as underweight, while a BMI above 25 is classified as overweight. Obesity – having a BMI of 30 or higher – is considered a very high risk for serious diseases, such as heart disease and cancer. A lot of people are “over-muscled” with bodybuilding programs, so this would be one example where there might be issues with BMI classification depending on bone size… but nonetheless, it should not change your weight too much (from studies I have seen). If you are bulking, you are gaining fat, so the BMI should be around 25 or more… if it isn’t, you are either not eating enough or bulking/cutting wrong.

For men, I believe anything between 18 and 21 is considered a normal BMI range. My weight fluctuates between 72 kgs-80 kgs depending on my workout intensity and energy requirements. The bigger problem with BMI calculations is that they don’t take into account levels of body fat percentage which can easily skew the result to show a person having normal BMI when he really shouldn’t be.

Personally, I think it’s necessary to have an idea of what your “ideal” body weight should be. The ideal body weight for someone depends upon his height too. A 5’9″ person would have a different ideal weight from a 6 feet tall person.

It was rarer when people were not so conscious about their body weight and they were okay with being fat or underweight, but now due to the changing trend, people are more concerned about their body weight. Society has become much harder on people who are obese or overweight. To maintain optimum good health, it is important that every individual maintains the right body weight; whether he needs to lose some pounds or gain some pounds. There are many factors that contribute towards maintaining the correct bodyweight like genetics, age, height, food habits etc. all these factors are responsible for deciding whether a person will be obese or underweight.
