About BMI Calculator
Body Mass Index (BMI) is a widely used screening tool that categorizes your weight relative to your height. While simple, it is a powerful first step in assessing metabolic risk. For Asian and Indian populations, standard international cutoffs often fail to capture the true risk of lifestyle diseases, which is why this calculator uses localized standards.
Scientific Basis
BMI is calculated as weight in kilograms divided by the square of height in meters (kg/m²). It was originally developed by Adolphe Quetelet in the 19th century. In 2004, a WHO expert consultation identified that Asian populations have higher body fat percentages and health risks at lower BMIs than Europeans, leading to the creation of lower cutoffs for the Asia-Pacific region.
Health Implications
A high BMI is a major risk factor for non-communicable diseases such as:
- Type 2 Diabetes: Risk increases significantly with a BMI over 23 in Asians.
- Cardiovascular Disease: Hypertension, stroke, and heart attack risks scale with BMI.
- Joint Issues: Excess weight puts mechanical stress on knees and hips (Osteoarthritis).
Actionable Tips
Focus on Protein: Increasing protein intake can boost metabolism and satiety.
Strength Training: Building muscle can improve your body composition even if your weight stays the same.
Track Visceral Fat: Don't rely on BMI alone; check your Waist-to-Hip ratio.
Limitations
BMI is a screening tool, not a diagnostic one. It does not distinguish between muscle and fat. Bodybuilders, pregnant women, and the elderly may get misleading results.
