hi! i am a little older than you and i way around the same weight as you. At your age you shouldn't have to be worrying about your weight. But I will still recommend
Explanation:
You should get involved in more sports. For example, i play tennis, soccer and basketball. I am vegetarian so my diet is kind of healthy but i sill like to eat sweets lol. Either way running daily would also help a lot and drinking lots of water. :)
