A simple formula will help determine whether you have a normal weight.
Body mass index - a formula that takes into account height and weight. This index should be considered as a hint, whether to lose weight or, on the contrary, it is time to gain weight. To determine your BMI, use this equation:
BMI = weight (kg) / rost² (m)Now that you have the value of the index, it is necessary to decode the scale approved by the World Health Organization:
- Lack of body weight - an index of less than 18.5,
- Normal weight - an index of 18.5-24.9,
- Possible obesity - an index of 25-29.9,
- Obesity of the first degree - 30-34,9,
- Obesity is the second degree - 35-39,9,
- Obesity third degree - 40.
Such an index is relevant for people over twenty years. For children and teenagers rates will be wider, and when it comes to older women or men aged, on the contrary, more stringent (with age, excess weight affects a person more negatively, respectively, even a small percentage extra kilos will be marked in the table as liquefaction).
Why to know the body mass index?
It is thought that such a simple way a person can own to determine whether he is at risk for many diseases associated with weight. For example, obesity, beginning in the second degree, increases the probability to be ill with diabetes, breast cancer, colon and prostate.The World Health Organization believe that every person should strive to index not higher than 24.9, however, point out that this figure is not 100% accurate.
