What is BMI?

Body mass index is a measure that determines whether your weight is appropriate for your height. It is calculated by dividing the weight in kilograms by the square of the height in metres.

BMI categories according to the World Health Organization

Under 18.5: 🔵 skinny
18.5 - 24.9: 🟢 Normal weight
25 - 29.9: 🟡 Weight gain
30 - 34.9: 🟠 Obesity, first degree
35 - 39.9: 🔴 Second degree obesity
40+: ⚫ Excessive obesity

📝 example: A person whose weight is 70 kg and whose height is 175 cm = 70 ÷ (1.75)² = 22.86 (normal)

💡 advice: BMI does not differentiate between muscle and fat. Athletes may appear overweight due to muscle mass.
