I want to lose a significant amount of weight I’m 16 and I’m about 180 and I would like to weigh about 120-130lbs. So what should I do and eat to lose this weight? Any help is appreciated and I will give points!

i need to lose weight by this thursday and i will do anything! like literally thing anything but surgery im 15 and 138 and im 5"7 and im very unhappy with my body and i need to lose weight by it either being not eating anything!

I dont have money to spend on gyms, pills, diet drinks, etc.

But links and websites and encouraging notes to help me stick to my diet would help too ^_^
