As you can see in the table above, girls are, on average, heavier than boys between the ages of 11 and 13. From the age of 14 the average weight for boys is higher again. Boys gain another 20 kilograms from 14 to 20 years of age. On average, girls only gain another 10 kilograms during this period. Girls gain more weight in the early teenager years than boys because, in general, girls hit puberty earlier and their body changes. When boys hit puberty their muscle mass increases and they are, on average, heavier than girls of the same age. So girls get a growth spurt before boys do.
