The table is based on the following age groups:

  • 18-30 years — optimal weight for young active individuals.
  • 31-45 years — taking into account reduced metabolism and potential changes in body composition.
  • 46-60 years — a more mature age group with possible hormonal changes and reduced physical activity.
  • 61+ years — considering reduced activity and changes in body composition with age.

These weight ranges are based on general BMI, and it is always better to consult a doctor or nutritionist for more precise recommendations.

BMI Formula

BMI = (Weight in kilograms) ÷ (Height in meters × Height in meters)

This is the basic formula, where:

  • Weight — your weight in kilograms.
  • Height — your height in meters, and it should be squared (i.e., multiplied by itself).
