BMI Calculator for Indians
Asians body types are different than the western people and so the obesity features differ too. That is why we see the difference in the overweight limit for the Asians.
And in recent statements made by some Indian researchers it has been mentioned that for Indians, the waist circumference (WC) also plays a vital role in measuring obesity.
Hence, both BMI and WC are important for measuring obesity in our Indian population.
While a BMI of 25 is considered to be healthy internationally, it has been reported that for Indians, more precisely the South Asians, the health quotient according to the BMI number may change.
The World Health Organization itself has accepted that major of the Asian population, who are at higher risk of diabetes and CVDs have BMI lower than the existing WHO- cut off points for overweight .
Hence it is accepted that for Indians the normal BMI cut off should be 23.
2 Factors that differ the health risks depending on BMI values between Asian and non-Asian are
- The fat content is found to be higher in Asian people.
- Moreover, the distribution of accumulated fat in the body is different in Asian and in Western people.
In a study conducted in the United States, it was found that people with a BMI of 25-29.9 kg/m2 had a 50% increased risk of diabetes compared to the people with BMI ranging between 18-24.9 kg/m2.

Difference between BMI calculator of men and BMI calculator of women
It has been found that women can carry more fat than men. Also, men carry more muscle. So this way a man and a woman with the same height will have different BMI.
Many studies have come up with different BMI gap between men and women.
However, even if men and women have different body structures, BMI threshold or the normal BMI value for both of them has been considered to be the same. This is basically taken up to keep it simple.
Scientific limitations of BMI measurements
While BMI chart for men/ women is a very popular way of identifying the weight of a person, it does have a few limitations.
- It doesn’t take the body fat measurement into consideration.
- BMI doesn’t change for men and women. However, as mentioned above there are differences of the body frame and muscular build up.
- BMI measurement cannot directly indicate any health disease.
