Hi ! To get slimmer one needs to reduce body fat percentage. And I'm sure you want it to be a long term result. & Fad diets don't work in the long term.  What works is a wholesome, balanced diet. And for losing weight you need to burn more calories than you consume. To be in a calorie deficit you can cut out  or restrict following foods from your diet : Fried or Oily foods, Sugary foods (deserts, cakes, soft drinks,packaged fruit juices, sweets) ,Foods containing Refined flour (maida or corn flour) and most packaged foods, fast food and starchy vegetables like potatoes. Eat whole foods like : Whole grains , fruits, vegetables, dals/pulses, low fat paneer, egg whites, grilled /steamed fish & chicken. And remember the rule of thumb: Eat enough food. But do not over eat. Ideally the diet should be customized as per individual requirement. More so because you're in a growth phase. Also take up a structured exercise program for gettin fit. Nothing looks as good as a fit toned body & only a combination of workout and diet can do that. All the best.
