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 163 pounds looks like, and below you can read the detailed report on BMI and the health that would apply for such a person.

BMI = 29

Your body mass index (BMI) is calculated as exactly 28.9 kilograms per square meter.

Health aspects

Your weight is at a somewhat elevated level; in our view, it may be less than optimal for your health. By classification of the WHO, you are "overweight".

Your body fat mass seems to be a slightly above average. But health ought not be affected provided your blood pressure, cholesterol and blood sugar levels remain at moderate values. This could be more likely if you have a higher muscle mass and a lower amount of body fat.

SBMI = 42/70

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 42/70 or "42 points out of 70".

Weight stability

At this weight level, you are at risk of gaining more weight. If you manage to maintain your current weight, you have reached your first and most important goal. Weight loss should only take the second place.

Your SBMI will decrease by about one point within ten years if you manage to keep your 163 pounds stable. This is due to the fact that the optimal, i.e. the "healthiest" BMI range increases with age, thus reaching higher BMI values.

Weight management

The best you can do is eat healthy food and increase your fitness. This will boost your health, whatever the case. If you lose weight in the process, all the better.

With a weight loss of 9 pounds down to a target weight of 154 pounds, your health would benefit.

By the way, being fat without tobacco is better than being slim due to nicotine. The best advice for smokers is to postpone the weight loss and stop smoking first. To curb a weight gain, the following suggestions may be helpful.


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. Walking or cycling may be better for your joints than jogging.

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 29, as a statistical group. They are non-personal. They should never replace medical advice.  Read more...
