BMI may do more harm than good, study warns

BMI overlooks key health factors, study finds.

Why it matters

  • BMI is widely used but has significant limitations.
  • It influences medical decisions and can reinforce stereotypes.

By the numbers

  • Two-thirds of Canadians are considered overweight or obese based on BMI.

The big picture

  • BMI doesn’t distinguish between muscle and fat.
  • It overlooks factors like age, sex, and race.

What they're saying

  • Some argue BMI is still useful for most people.
  • Others highlight its known limitations and problematic history.

Caveats

  • BMI was originally a statistical tool, not a health measure.
  • Authors advocate for rejecting BMI or using it with caution.

What’s next

  • Possible paths include using more nuanced measures or rejecting BMI altogether.
