Hi . My dd 8.9 yo has suddenly put on few kilos. Her height is 138 cms weight 40.7 kilos. Mostly her fat is gathered in her tummy. She is a very active child and regularly plays sport. Eats chocolates once in a week. Not having a sweet tooth. Regularly eats fruits & veges. Eats too less junk, sometimes only over the weekends. Am wondering why is she putting on so much weight. The doc says she is overweight. Kindly help!
