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 179 cm and a weight of 108 kilograms. If it does not seem to be correct, feel free to check your entries.

BMI = 34

Your body mass index (BMI) is calculated as exactly 33.7 kilograms per square meter.

Health aspects

Your weight is at a high level; in our view, it can contribute towards health problems. By classification of the WHO, you are "obese".

Your body fat mass seems to be rather high. It may have raised your blood pressure and cholesterol levels, or affected the way your body handles blood sugar. Your doctor could tell you whether you are at risk for heart disease, stroke, or diabetes, or not.

SBMI = 51/70

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 51/70 or "51 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. Next you may want to lose weight: Do this slowly but surely.

Your SBMI will decrease by about one point every five years if you manage to keep your 108 kilograms 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 reach your weight target, all the better.

Your target weight of 79 kilograms

Your weight target is in the right direction but very ambitious. A fast weight loss of 29 kilograms could be the initial phase of a yo-yo effect. It may be safer to try 9 kilograms first, stabilize on the level of 100 kilograms 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 men at 34 years of age with a body mass index of 34, as a statistical group. They are non-personal. They should never replace medical advice.  Read more...
