going to the gym everyday would help. depending on what grade she is in though she should have gym everyday and if shes sixteen then she is in High school. If she ran to the school instead of walking that would also be alot of help. If she has animals she could walk them. Riding her bike to school. Riding a sk8 board. There are all sorts of different thing that will help her. The main one though is to not eat so much junk food maybe just a half od a choclate bar every other day and eating more vegetables than Junk food.
