What Does BMI Mean?
BMI stands for Body Mass Index. It’s a numerical value calculated using your weight (in kilograms or pounds) divided by the square of your height (in meters or feet).
BMI = weight (kg) ÷ height (m²)
It’s a widely accepted method for assessing whether your body weight is appropriate for your height—and a quick indicator of potential health risks related to weight.
Why You Should Calculate BMI
Calculating your BMI is a great first step toward taking charge of your health. Here’s what it can help with:
Identifying health risks such as heart disease, type 2 diabetes, and hypertension
Setting fitness or weight goals more accurately
Tracking progress on your health or weight loss journey
Making informed lifestyle changes
While it’s not a perfect measurement, it provides a useful starting point for assessing overall health.
BMI Categories and What They Indicate
Once you calculate BMI, your number will fall into one of the following health ranges:
| BMI Range | Health Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
Each category carries different health implications. Knowing your BMI helps you make smart choices toward better wellbeing.

Is BMI a Perfect Health Indicator?
While it’s a great starting point, BMI doesn’t tell the whole story. It doesn’t account for:
Muscle mass (you may appear overweight when you’re actually very fit)
Fat distribution (where fat is stored matters)
Age, gender, and body composition
That’s why it’s best to calculate BMI alongside other health indicators like waist-to-hip ratio, body fat percentage, or medical advice.
What to Do After You Calculate BMI
Once you know your BMI category, here’s what you can do:
Underweight: Focus on high-nutrient foods and consider strength training
Normal weight: Maintain with regular activity and balanced nutrition
Overweight/Obese: Make gradual lifestyle changes—think better food choices and consistent movement
Even small changes can lead to big health improvements over time.
