How Do I Calculate My BMI

BMI (Body Mass Index)

is a simple measurement used to assess whether your weight is appropriate for your height. It helps identify if a person is underweight, at a healthy weight, overweight, or obese.

BMI (Body Mass Index) = Weight (kg) ÷ Height (m²)

BMI Classification:

  • Below 18.5 – Underweight
  • 18.5 to 24.9 – Healthy Weight
  • 25.0 to 29.9 – Overweight
  • 30.0 and Above – Obese

Example:
If your weight is 80 kg and your height is 1.70 meters:

BMI = 80 ÷ (1.70 × 1.70) = 27.7

This falls in the Overweight category, and an USG Abdomen may be required as part of your metabolic assessment.

However, BMI has some limitations:

  • Women naturally tend to have a higher percentage of body fat than men at the same BMI.
  • Men generally have more muscle mass, which can make their BMI appear higher even when they have low body fat.
  • BMI does not distinguish between fat, muscle, bone, or body composition.

For metabolic health assessments, especially in programs such as DLife Metabolic Reversal, additional measurements are often more informative:

  • Waist Circumference
  • Waist-to-Height Ratio
  • Body Fat Percentage
  • Fasting Insulin
  • HbA1c
  • Lipid Profile
  • Liver Function Tests

GenderIncreased Risk
Men More than 90 cm (35.4 inches)
Women More than 80 cm (31.5 inches)

A person may have a "normal" BMI but still carry excess abdominal fat and have insulin resistance or metabolic syndrome. Therefore, BMI should be considered alongside waist measurements and metabolic blood tests rather than as the sole indicator of health.
