Is it easier for you to lose weight as a kid?

Im 15 years old weighing 130 pounds. i know thats perfect weight for a 15 year old but im 5 foot 6 and i have chubby cheeks, fat around the pectorals, and a chubby stomach. not many people think im fat but i just want to lose a little weight before summer. oh and i am just starting puberty i dont know if that helps. i just want to lose a little weigh so is it easier for a kid to lose weight rather than an adult?
