under 18.5kg/m2 – you are considered underweight and possibly malnourished. 18.5 to 24.9kg/m2 – you are within a healthy weight range for young and middle-aged adults. 25.0 to 29.9kg/m2 – you are considered overweight. over 30kg/m2 – you are considered obese.
Example: If a person weighs 68 kg and is 165 cm (1.65 m) tall, BMI is calculated as 68 ÷ (1.65)2 = 24.98 kg/m2, which means that the person has a BMI of 24.98 and is considered to be a healthy weight. Body mass index (BMI) is an approximate measure of obesity.
Normal or healthy weight = BMI 18.5-24.9 kg/m. Overweight = 25-29.9 kg/m. Obese = 30 – 39.9 kg/m. Extremely Obese = 40 kg/m2 or greater.
