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.
Overweight is defined as a body mass index of 25.0 to less than 30.0 kg/m². People with BMIs in this range have an increased risk of type 2 diabetes, hypertension, and cardiovascular disease. Obesity is defined as a BMI of 30.0 kg/m² or greater.
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.
If your BMI is 18.5 to <25, it falls within the healthy weight range. If your BMI is 25.0 to <30, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obesity range.
This means a person with a height of 150cm and a weight of 45kg would have a BMI score of 20. According to the BMI, that person would be in the “healthy weight range”.

What should your waist measurement be? For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high.
While being overweight is a precursor to obesity and, like obesity, can increase the risk of diabetes, heart attack and stroke, it's also possible to be overweight and still healthy, especially if you're free from chronic diseases like hypertension or diabetes.
Individuals are usually considered morbidly obese if their weight is more than 80 to 100 pounds above their ideal body weight. A BMI above 40 indicates that a person is morbidly obese and therefore a candidate for bariatric surgery.
Four phenotypes of obesity have been described, based on body fat composition and distribution: (1) normal weight obese; (2) metabolically obese normal weight; (3) metabolically healthy obese; and (4) metabolically unhealthy obese.

It gave the ideal weight according to height and the following formulae were used in traditional weight calculators: Ideal body weight (men) = 50 kg + 1.9 kg for every inch above 5 feet. Ideal body weight (women) = 49 kg + 1.7 kg for every inch above 5 feet.
The CDC report that the average weight of a 12-year-old male is 89 lb , or about 40 kg.
