SBMI Chart

low moderate high very high health risk

This SBMI chart shows your BMI value and its age-dependent significance for the health. Your value is marked in the centre of the highlighted area.


The calculation of the body mass index is based on a height of 5 feet 8 inches (173 cm) and a weight of 199 pounds (90.3 kilogrammes). New calculation?

BMI = 30

Your body mass index (BMI) is calculated as exactly 30.3 kilogrammes per square metre.

Health aspects

Your weight is at a somewhat elevated level; in our view, it may be less than optimal for your health. Contrary to the WHO classification of "obese", we hold the statement that you are only "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 = 43/70

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 43/70 or "43 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 199 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.

Your target weight of 160 pounds

Your weight target is in the right direction but very ambitious. A fast weight loss of 39 pounds kilogrammes could be the initial phase of a yo-yo effect. It may be safer to try 12 pounds first, stabilize on the level of 187 pounds and then set a new target, if this seems sensible.

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.


Never diet again. 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.

Your earlier diet

Would you like to specify the diet type? A good diet supplies the body with a well-balanced, mainly plant-based mix of carbohydrates, fats, proteins, minerals, vitamins and with enough, but not too much energy.

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