How could a poor student maintain a healthy diet and lose weight?

Speak to a dietician: You should aim for a balanced diet, especially eating a breakfast that contains a reasonable amount of protein and is low in carbohydrates. Diets with the proper balance of protein, carbohydrates and fat are contained in many standard diet books. Beware of fad diets that promise great weight loss without much effort. You should begin exercise at least 3-5 times per week.
