Xta, I took a quick look at your profile. I'm afraid there there is no "diet that actually works" that will make you lose 10 kgs in a couple of weeks. What DOES work is slower and consistent weight loss using the tools available here on FatSecret.
At 77 kgs, you're hardly gonna be the "fat one" there.
If you're not comfortable with your size, I suggest you look around on the website, find a diet that suits your needs and your life style and take a longer term dedication to doing this.
It can be done, and it doesn't have to be difficult. I'm living proof.
I hope you reach your goals and enjoy the ride.
