Weight loss help

Marrissa • Lil Riss💕

I am 19 years old, 5’1 and I weigh about 155lbs. I’m trying to figure out the best way to drop down to about 120lbs. I really only want to lose the fat in my stomach. I’m happy with my butt and what not but I do want my stomach to be smaller. So if anyone has any advice on how to be my proper weight pretty quickly for my height and age I would appreciate it!
