Does anyone know a diet plan for teenager or that's easy to follow?

I'm so frustrated cause I want to start a diet to loose weight and I've been searching around and what i find is simply more blah blah on diets or this crazy recipes that must be done with tons of condiments and stuff that I don't have or don't eat, specially in school so I would really like to hear from some of you guys and your experiences with weight loss and some diets that have worked for you.
