What the BMI Categories Mean.
BMI is grouped into four broad ranges used by healthcare providers as a starting point for discussing weight and health.
Underweight
May indicate insufficient energy intake for your body's needs.
Healthy Range
Generally associated with lower risk of weight-related health conditions.
Overweight
May benefit from lifestyle changes or, where appropriate, medical support.
Obesity Range
Associated with increased risk of several weight-related health conditions.
What Is BMI, and How Is It Calculated?
Body Mass Index (BMI) is a simple screening measure that uses your height and weight to give a general indication of whether your weight falls within a typical range for your height.
The Calculation
BMI is calculated by dividing your weight in kilograms by your height in metres, squared.
Why It's Used
BMI is widely used by healthcare providers as a quick, low-cost starting point for conversations about weight and health — including as one factor considered when assessing eligibility for certain weight management treatments.
BMI Has Limitations.
BMI is a useful starting point, but it doesn't tell the full story about anyone's individual health. Here's what it doesn't account for.

Answers to the questions we're asked most often about BMI and what your result means.
A BMI between 18.5 and 24.9 is generally considered within the healthy range for most adults. Below 18.5 is classified as underweight, 25–29.9 as overweight, and 30 or above as the obesity range.
BMI is a useful general screening tool, but it doesn't distinguish between muscle and fat, so very muscular individuals may show a higher BMI without excess body fat. It also doesn't account for age, sex, ethnicity, or where fat is distributed in the body — all of which can affect what's healthy for a specific person.
The standard BMI formula and categories are the same for adult men and women. However, body composition naturally differs between sexes, which is one reason BMI is best used as a starting point rather than a complete health assessment.
There's no strict rule, but checking every few months alongside your weight management journey can help you track general trends over time. It's less useful to check daily, since normal weight fluctuation can shift the number without reflecting any real change.
Your BMI is one factor among several that can inform a conversation about weight management. The most useful next step is a consultation, where your full health history and goals can be considered alongside your BMI to explore what's appropriate for you.
BMI is typically one of several factors considered when assessing suitability for weight management treatments, often alongside any weight-related health conditions. Final eligibility is determined by a licensed physician during consultation, not by BMI alone.
