Who can give me good advice on how to lose weight fast?

I’m a 15 yr. old girl who is struggling 2 lose weight, and I really want 2 lose weight fast by this summer, and if anyone has good advice and knows what I can do, then please answer. Please Answer!
~Thanks for all ur help!
The problem is though, I really don’t go out much (because of my parents) so I kinda need a plan at home.
Thanks!
