What is BMI?

Your Body Mass Index (BMI) indicates whether you have a healthy weight based on your height. You calculate your BMI based on your gender, age, height and weight. This index is suitable for men, women and children from 2 to 70 years who have a normal physique. For strength athletes or women who are pregnant, BMI is less meaningful.

75 / (1.67 * 1.67) = 26.9

BMI calculator for women

In the big picture it does not distinguish between men and women. However, this is different in women who are pregnant or breastfeeding and it's not advisable for them to calculate their BMI. The body weight gained will be because the baby grows and will place a pregnant women in the wrong category.

BMI calculator for children

Because children are growing, it makes BMI calculations less relevant and doesn't distinguish between boys and girls. A good BMI calculation table does take into account a child's age and sex. Do you think your child does not have a healthy weight? Please contact your doctor or a dietitian.
