When managing weight, knowing your BMI helps you:

  1. See if excess weight is affecting blood pressure, cholesterol, or heart function1
  2. Understand your risks of developing liver diseases2
  3. Track weight to reduce insulin resistance & PCOS-related hormone imbalances3
  4. Maintain a healthy weight to support regular menstrual cycle4

What is BMI, and why does it matter when managing weight?

Body Mass Index (BMI) is a simple measurement that compares your weight and height to indicate whether you are within a healthy range 1. While it does not measure body fat directly, BMI is a useful starting point for understanding weight-related health risks 1. A higher BMI can be associated with risk of type 2 diabetes, heart conditions, liver disease, PCOS, and infertility 5, 6, 7, 8. Knowing your BMI can help you make informed decisions to support your long-term health.
BMI is a calculation of a body person’s weight (in kilograms) divided by the square of their height (in meters). For adults 20 and older, BMI categories are based on a person’s BMI regardless of age, sex, or race.9
