BMI calculator

BMI is your weight in kg divided by your height in metres squared. For Asian adults, including Indians, a WHO expert group suggested lower cut-offs: 23 for overweight and 27.5 for obesity, instead of 25 and 30.

How it works

  • BMI = weight (kg) / height (m) x height (m).
  • WHO standard: under 18.5 underweight, 18.5 to 24.9 normal, 25 to 29.9 overweight, 30 and above obese.
  • Asian cut-offs (WHO expert consultation, 2004): 23 to 27.4 overweight, 27.5 and above obese.
  • BMI ignores muscle. Lifters with a lot of muscle can read overweight while being lean.

Kynetix works these out from your profile and adjusts them as you train and log. See the app.

Questions

What is a healthy BMI for Indians?

Between 18.5 and 22.9 on the Asian cut-offs. Above 23 counts as overweight there, earlier than the standard 25.

Is BMI accurate for people who lift?

Not very. It cannot tell muscle from fat, so a muscular person can score high. Waist size and how your clothes fit tell you more.
