What Is BMI?
BMI (Body Mass Index) is a simple and widely used method to estimate whether your weight is healthy in relation to your height. It’s calculated using the following formula:
BMI = weight (kg) ÷ [height (m)]²
Your BMI number helps categorize your body weight as underweight, normal weight, overweight, or obese, providing a general idea of your health condition.
Although BMI doesn’t measure body fat directly, it’s a reliable indicator for most adults and is recommended by health organizations like the World Health Organization (WHO).
Why Is BMI Important?
Your BMI is one of the easiest indicators of your overall health. It helps you:
-
Understand whether you need to gain, maintain, or lose weight.
-
Detect potential health risks early.
-
Set realistic fitness and nutrition goals.
-
Track your body changes over time.
Remember, BMI is a screening tool, not a diagnosis. Factors like muscle mass, bone density, and age can slightly affect accuracy — especially in athletes or elderly people.
How to Calculate Your BMI
You can calculate BMI manually using this formula:
BMI = Weight (kg) ÷ Height (m)²
Example:
If your weight is 70 kg and height is 1.75 m:
→ BMI = 70 ÷ (1.75 × 1.75) = 22.86 (Normal Range)
Alternatively, just enter your weight and height in our BMI Calculator above and get the result instantly.
How to Improve Your BMI Naturally
If your BMI falls outside the healthy range, consider these simple lifestyle improvements:
-
Eat balanced meals – Focus on whole foods, vegetables, and lean proteins.
-
Exercise regularly – Aim for at least 30 minutes of activity 4–5 days per week.
-
Stay hydrated – Drink enough water throughout the day.
-
Get proper sleep – Aim for 7–8 hours of quality rest nightly.
-
Track your progress – Recheck your BMI monthly to monitor changes.
Small, consistent habits are more effective than drastic short-term diets.
