Lean diet plans

Hey, I need help as well. I really need to lose this extra weight more so in the mid-section area. I am 5'8 and weigh 193. My body fat percentage is around 22% but I want to get down to like 10%. I am not good at dieting at all. I am a college student and on a budget. Right now I am not meeting my required calorie intake. It's suppose to be at around 2200 and i'm only getting about 1100. Any good diet plans out there? Does calorie intake really matter? I've never been much of a eater. Use to eat only about one big meal a day and be ok. Right now i have 1% milk, go lean cereal, protein powder, carrots, yogurt, cup of fruit, salad mix, tilapia, and chicken wings.
