Diet calculators

Below is a set of diet calculators that you might use to analyze your condition and the results of your diet. The calculators are based on formulas used by professional dieticians to asses a patient's condition. Each calculator examines only selected aspects of our body, so the result will not always be entirely suitable. We recommend using all of the calculators, and if in doubt, do not hesitate to contact our dieticians.

BMI Calculator - Body mass index calculator or Quetelet II index defines the relationship between body mass and height. BMI is calculated by dividing body mass by the square of height in metres. By calculating BMI we can assess if we are in a group at risk of weight disorders. BMI is not a credible index of disease risk, but it can be a first signal that your weight is not correct. Thanks to this we can take immediate action to re-establish the 'ideal weight'. BMI is not a credible index if:

  • you are pregnant
  • you are very muscular
  • you are still growing
  • kg

    WHR Calculator - WHRCalculator - waist-hip ratio. It is used to define the type of obesity and the adiopse tissue distribution. WHR is used as a measure of two types of obesity:

  • abdominal obesity
  • rump and thigh obesity
  • Abdominal obesity means accumulation of adiopse tissue inside the abdominal cavity. Rump and thigh obesity means accumulation of adiopse tissue in lower parts of the body. It is important to properly measure our body parts before we put the data into the calculator. Women should measure their waist half-way between the bottom part of the rib arch and top side of the hip bone. Hips should be measured at the widest part. Men should measure their waist exactly oat the level of their navel, and hips at the level of the bottom end of the hip bone.
    The ideal ratio for women is 0.8 or near to this, for men it is 1 or near to this. Ratios which significantly differ mean a high risk of diabetes, ischaemic heart disease, and many other diseases related to obesity. It this case you should seriously think about a diet. Contact our dietician to consult your case.

    TER Calculator - calculates your Total Energy Requirement in calories per 24 hours. TER is the sum of AMR and BMR results. TER calculators show the number of calories used daily which allow us to maintain, decrease or increase body weight by eating more or less calorific meals. To achieve the desired goal we need to change our diet or physical activity.
