I am 12 years old I am a skinny person I only have 10% of fat in my body but my doctor claims I'm still very healthy. The average would be around 17%.
Well mine body fat is 9% according to Internet body fat calculate stuff;p and I'm a boy...
The average body fat percentage a 13-year-old should have depends on their gender and height. It is usually around 25 percent.
12% - 16%
well a 13 year old should not have more than 45% body fat i hope this helps if not sorry
It doesnt matter if. You should work out and eat healthy if you want to have less body fat.
