If your BMI is: 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.
45 (kg) divided by 2.25 (height squared) = 20. 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”.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
BMI values of less than 18.5 kg/m2 are considered underweight. BMI values between 18.5 kg/m2 to 24.9 kg/m2 are healthy. BMI values between 25 kg/m2 to 30 kg/m2 are overweight. BMI values greater than 40 kg/m2 are considered obese.
ICMR-National Institute of Nutrition (NIN) has redefined the ideal or reference Indian adult man and woman with regard to age to 19-39 years instead of 20-39 years. The body weight has been put at 65 kg for males and 55 kg for females while earlier, it was 60 kg and 50 kg respectively, which are a decade old.
55kg is normal weight for most of people. The weight range for 13-year-old boys is between 75 and 145 pounds. Weights in the 50th percentile for this age land at 100 pounds.
Clinically underweight or dangerously skinny for a man would be: A BMI of 15, 16, 17, or 18. A weight of 100–120 pounds (46–55kg)
Even though a 13 year old who is 70 kg is considered to be overweight as they suggest you should be weighing more like 50 to 60 plus kg, you are a growing teenager (providing that you are still growing, I'm only saying this because when I was your age I stopped growing unfortunately for me).
The CDC report that the average weight of a 12-year-old male is 89 lb , or about 40 kg.
From a clinical perspective, an individual is considered “too skinny” if they are deemed underweight. According to the Centers for Disease Control, an individual is underweight if their Body Mass Index (BMI) is below 18.5 [1].
Women with a BMI of less than 18.5 are considered underweight. The average woman's height is 5 feet, 4 inches. If you weigh 107 pounds or less at this height, you are considered underweight with a BMI of 18.4. A healthy weight range for that woman would be 108 to 145 pounds.
The best measure of whether you are a healthy weight is the body mass index (BMI). This is calculated using your weight and your height. In adults, a healthy weight range is a BMI of 18.5 to 24.9. If your BMI is under 18.5 then you would be considered underweight.
under 18.5kg/m2 – you are considered underweight and possibly malnourished.
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.
The average weight for 12 year old boys is 40.7 kg and 12 year old girls average 41.8 kg 1 The tables below show the distribution of weight by percentile of the 12 year year old population. Current units = kilograms.
If your BMI is less than 18.5, it falls within the underweight range. 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.
Assuming you have an average height for your age of 160 cm, you are not overweight, but underweight! A girl of your age should weigh at least 62 kg, and all the way up to 87 kg.
For example, a 7-year-old boy who is 3 feet 11 inches (119 cm) tall would have to weigh at least 56.9 pounds (25.8 kg) ( BMI = 17.9) to be considered overweight, and a 13-year-old girl who is 5 feet, 3 inches (160 cm) tall would be considered obese if she weighed 161 pounds (73 kg) ( BMI = 28.5).
According to the Centers for Disease Control and Prevention (CDC), most 13-year-old girls weigh around 76–148 pounds (lb) and most 13-year-old boys weigh between 75 and 145 lb, but this can vary widely. The average weight of a 13-year-old will depend on a number of factors.
The healthy weight range is actually broader than many people think it is. For example, a person who is 170 cm (5'7") tall has an ideal weight range of 118 lbs. to 159 lbs. (53.5 kg to 72.3 kg).
Using a height of 1.73 m (5 ft 8 in) as a guide, as it squares to three and also lies conveniently between average adult male and female heights, overweight is defined as 75 kg and obese as 90 kg. The risk of the extra 15 kg, or 33 lb, is modest when compared with other risk factors.
