Thug.... first how old are you , how much do you weigh, how tall, any pics possibly?
If your just looking to get into shape, and not become massive, your still going to want to put on some muscle, even if its a minimal amount. The more muscle you have on your body, the more calories you will burn naturally. It doesnt have to be a lot of muscle, maybe just 5 or 10 lbs, but that would make all the difference in the world, if you could replace the few little lbs of fat on your waist with maybe 5 lbs of lean muscle on the rest of your physique.
First you need to tell us what you eat, what your daily eating habits are, and how often you eat. You are going to want to eat 4 to 5 small meals a day. How much you eat depends on what you weigh right now, and if you want to gain or lose weight.
Working nights shouldnt be much of a problem. You can still eat healthy choices throughout whenever you eat your meals. Try to remeber to eat something small every 3 to 4 hours. Maybe no more than a snack like fruit or a powerbar, or something like that, but something is better than nothing.
You also may want to invest in some protein powder. Try having a shake a day, and if you can afford it, two is even better. Try mixing it with some skim milk and a banana for a healthy meal, if you dont feel like preparing something. Fruits and vegtables are things you can pretty much eat whenever you want. They are a good source of vitamins and antioxidants, and contain little or no fat. Fruits do have sugar (fructose) and carbs, but as long as you dont eat 10 apples a day, the benefits far outweigh anything. ]
You will want to avoid certain foods. Anything high in fat and calories, things like hamburgers, hotdogs, pizza, things that are high in carbohydrates. Carbohydrates are energy soucres for the body, and you need a certain amount of carbs a day for energy. Same thing with calories.
The thing is, if you dont use those carbs and calories, they usually get stored as fat. So the kind of carbs you want are the ones that burn slowly, like oatmeal, yams, vegtables, whole grains, things like that. They burn slowly in the body, and dont add as much bodyfat as something like a candybar, which is pure sugar, and will give you fast energy, but will dropoff and youll feel worse, and hungry for more, faster.
So post your stats, and what you eat, and we'll go from there.
The basic Idea is to clean up your diet, eat smaller meals more frequently, and avoid alcohol as much as possible.
Also, start an exercise program. Whether its running, or basketball, or lifting weights, doing activities will help get you into shape, and help you lose fat faster than diet alone.
