text: she is 148 and she is 13 and her height is 5'3? my little cuzin weighs 148 and she is 13 and her height is 5'4 i dont know what to tell her is she overweight i agree with most other comments, she still is young and her body may change a lot (and for the batter) as she grows, however, i think you shold try to get her a little more active, like taking a walk, swimming, bike riding, or getting her to tr out for a sport, that way she can get some more exercise, possibly lose some wight, but still not put her at riskfor still being young.  also, try checking her diet, a little junkfood averyday can go a long way, so maybe try taking her out to healthier places for lunch or dinner, and make it a treat for both of you so you can both, (her especially) enjoy a healtier lifestyle.  hope that offers some help!!!
