SBMI Chart

low moderate high very high health risk

This is what the SBMI chart of a women at 40 years of age, a height of 5 feet 3 inches and a weight of 104 pounds looks like, and below you can read the detailed report on BMI and the health that would apply for such a person.

BMI = 18

Your body mass index (BMI) is calculated as exactly 18.4 kilograms per square meter.

Health aspects

Your weight is at a marginally lower level; in our view, it still should still be fine for your health. By classification of the WHO, you are "underweight".

Your low body mass will not be a problem for your health provided you are getting sufficient amounts of vital substances such as protein, minerals, vitamins and essential fats. A low but stable weight may be fine, but an unintended weight loss could be a sign of poor health.

SBMI = 27/70

This assessment is based on the newly developed Smart Body Mass Index. Its ideal range is between 30/70 and 39/70.

Your Smart Body Mass Index (SBMI) is calculated as 27/70 or "27 points out of 70".

Weight stability

Do not lose any weight. A small gain in weight could be beneficial, preferably by building up muscle mass.

Weight management

With a weight gain of 6 pounds up to a target weight of 110 pounds, your health would benefit.


Eat a variety of foods that you like, optimally including five servings of fruit and/or vegetables a day. Avoid eating too sweet, too fat and too much.

Physical activity

Do physical exercise at least for half an hour daily at moderate to vigorous intensity.

Important to know

This feedback can only be based on the inevitably limited extent of the data that you have entered here. This data has been evaluated by comparing it with the results of the most comprehensive study published so far on the BMI and its associated health risks.

The results and comments above can only give you an estimate that applies to all women at 40 years of age with a body mass index of 18, as a statistical group. They are non-personal. They should never replace medical advice.  Read more...
