Is there a right diet for teenagers?

I've been looking for a diet that will be effective fast. The crash diets haven't worked, and I'm almost desperate. Please help?Is there a right diet for teenagers?
What you do is cut out alot of sugar and eat healthier. I am an african american teen. i'm 14 years old i want to lose weight also. if you stretch, exercise properly and do it on a regular. Run or jog. Trust me you will lose weight. The only thing is you have to be dedicated. That was my problem i'd say i was going to do it but i was dedicated. i'm serious now. I dance more like hip hop and alot of dance outfits and also dances cause me to show my stomach i always think if nothing else a flat stomach will be the key to your sucess regardless of what you do. But good luck stay dedicated and i hope this helps!!Is there a right diet for teenagers?

Cut out junk foods and sugar treats/pop. Get active. No fast food.
