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 center of the highlighted area.


The calculation of the body mass index is based on a height of 5 feet 9 inches (175 cm) and a weight of 170 pounds (77.1 kilograms). New calculation?

BMI = 25

Your body mass index (BMI) is calculated as exactly 25.1 kilograms per square meter.

Health aspects

Your weight is at the level that, in our view, should be optimal for health. We hold this statement contrary to the "overweight" classification of the WHO, read why ....

With a good balance of body fat and muscle mass, your blood pressure, cholesterol and blood sugar values are likely to remain at moderate levels. You would then seem to be well-protected against a heart attack, stroke or diabetes. This might be less so if your body fat is higher with a lower muscle mass, if you consume tobacco, other drugs or too much alcohol, lack physical activity or sleep, eat unhealthy food, or suffer from stress and other unhealthy life factors.

SBMI = 36/70

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 36/70 or "36 points out of 70".

Weight stability

A stable weight at this level is fine, especially if you keep fit.

Your SBMI will decrease by about one point within ten years if you manage to keep your 170 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?

This is no issue for you, luckily. But you may want to consider some suggestions that are well-advised, not only for weight reasons.

At the age of 65, a weight loss is far less important than it may have been earlier in your life. Keep this in mind when reading the following comments.

Your target weight of 150 pounds

You are already in your optimal weight range. Losing weight would add no benefit to your health.


Think over your diet. 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 current diet

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. If your diet does not meet this standard, feel free to change it.

Physical activity

Do physical exercise at least for half an hour daily at moderate 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 65 years of age with a body mass index of 25, as a statistical group. They are non-personal. They should never replace medical advice.  Read more...
