What is Body Mass Index (BMI)?
Body Mass Index (BMI) is a simple screening tool commonly used to estimate body fat. It is calculated by dividing your weight in kilograms by the square of your height in meters. While not a direct measure of body fat, it correlates with direct measures and is an effective screening tool for weight categories that may lead to health problems.
How to Use This Calculator
- Select Unit: Choose between Metric (CM/KG) or US (Feet/Pounds).
- Enter Height: Input your accurate height.
- Enter Weight: Input your current weight.
- Indian Standard Toggle: If you are of Asian descent, check this box. Research suggests Asians face health risks at lower BMI levels than Western populations.
BMI Formula
The standard formula used globally is:
BMI = Weight (kg) / Height² (m²)
For the US System: BMI = [Weight (lbs) / Height² (in²)] × 703
Health Risks of Abnormal BMI
Being outside the normal BMI range can significantly impact your health:
- Underweight: Risk of malnutrition, osteoporosis, and weakened immunity.
- Overweight/Obese: Higher risk of Type 2 Diabetes, hypertension, heart disease, sleep apnea, and certain cancers.
Frequently Asked Questions (FAQ)
No. BMI does not distinguish between muscle mass and fat. Athletes and bodybuilders may have a high BMI due to muscle weight but still be healthy with low body fat.
Research shows that Asian populations tend to accumulate abdominal fat more easily, increasing the risk of metabolic diseases (like diabetes) at a lower BMI compared to Caucasian populations. Hence, the cutoff for "Overweight" is lower (23 instead of 25).
For the most consistent results, weigh yourself first thing in the morning, after using the restroom and before eating or drinking.
Healthy weight loss is gradual (0.5 to 1 kg per week). Rapid weight loss often results in muscle loss rather than fat loss. A balanced diet and regular exercise are the best ways to sustainably lower your BMI.
