I do the workout and sports required. Cutting on food is a difficult thing, so I cut the fat-containing food like cheese from my diet for a few months. Suddenly altering my diet is not possible, so I stop eating unhealthy food one by one. I talk to my parents about it and make them understand. If I lose a fixed amount of weight in a week I reward myself with a cheeseburger at the end of the week, and then start working on my diet plan again, feeling motivated.
