1.) You can't lose fat in just one area of the body. That is called spot reduction, and it does not work. Doing 300 crunches a day will not give you a 6-pack when you have a keg shaped stomach, it will just create abs underneath all that disgusting fat. You have to lose fat everywhere.
2.) keep your daily calorie intake at 1800-2200. If you don't know the calorie content of your foods or the ballpark of it, then you'll be fat forever. educate yourself.
3.) do weights 3x a week, cardio 4x a week (all on seperate days. Lifting weights will increase muscle mass, which in turn will increase your metabolism and make you burn off more fat at rest. supplement protein after both cardio and weights.
4.) cardio sessions should not be longer then 15 minutes.
5.) they should be done with high intensity. what that means is, when you do cardio, it should go like this:
jog for 30 secs
sprint for 30 secs
jog for 30 secs
sprint for 30 secs...
for the 15 minutes. Don't do long cardio sessions, because you will lose muscle mass. Also there has been a study (can't find the link) that proved short duration high-intensity cardio is much more efficient at burning fat in your body then long duration steady cardio.
edit:
6.) only drink water, and drink LOTS of it.
