How can i loose weight, easily?

Ok, so i'm 12 years old and turning 13 in November and I weigh 138 lbs. My doctor said I should weigh abut 110.... I really dislike being overweight, I hate it actually! I would just like to know, how, could I loose the POUNDS. I believe i'm like 5'1/5'2 ish. Could you guys recommend like exercises that help remove fat from the stomach and thighs and the rear, tips? Please don't tell me to count calories cause i don't really know how to do that or to buy some special protein of some sort cause i wanna loose weight not my money, so yeah, thank you so much! :)
