What is the average weight for a 13-year-old? 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.
It's expected that all tweens will experience a weight increase, called preteen weight gain. When you look at the total amount of weight gained across the span of the teenage growth spurt, it is significant. That awkward, pudgy appearance many tweenagers go through is a completely normal part of puberty.
Your weight (150 pounds) is in the Healthy Weight category for adults of your height (5 feet, 9 inches). BMI is a screening measure and is not intended to diagnose disease or illness. For more information, visit About Adult BMI.
A healthy weight would range from about 55 to 75 kg. If you are 150 kg you are morbidly obese.
Lean body mass in girls diminishes from approximately 80 percent to 75 percent by the end of puberty, while the amount of body fat increases. In comparison, the percentage of lean muscle mass in boys increases from about 80 percent to 90 percent by the time they reach adulthood.
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).
A 13-year-old boy who is 4' 10" should weigh between 92 and 103 pounds; a girl of the same age who is 4' 6" should weigh between 97 and 110 pounds. The average weight for 13-year-olds is between 90-100 lbs. For a male, the average height is 5'2", while the average female height is 4'8".
Adult Body Mass Index
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.
Noticeable weight gain may occur prior to a growth spurt as excess fat helps promote growth. As a child goes through puberty, their stores of body fat may change.
The changes that come with puberty include weight gain and, in guys, broader shoulders and increased muscle mass. Because everyone is on a different schedule, some of your friends may have started puberty when they were as young as 8 (if they're girls) or 9 (if they're guys).
Your child will experience many changes in their body during this time. For girls, puberty usually occurs between ages 10 to 14, and for boys, between ages 12 to 16.
BMI weight ranges
below 18.5 is underweight. between 18.5 and 24.9 is healthy. between 25 and 29.9 is overweight.
Until that 18-20 year mark, it is normal to see 5-7 kg (11-15 lbs) of weight gain each and every year. Adolescents should not weigh less than they did the day before. Here is the expected average weight gain of teenagers by age group: 12-13 years of age: 5kg per year.
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.
