first of all you need to sort out your diet mate, if you wana lose all your fat try to eat very small or no amounts of carbohydrates per day specially after 4pm as thats when your metabolisam slows down.
make sure you don't eat any fried food or crap like that and drink lots of water.

as for the exercising cycling and walking fast up the hill are the best ones to burn fat.

and for the supplements try flaxseed oil as it is a natural fatty acid and will burn your bodys fat.
another strong one is thermobol from maximuscle, i was taking them back in summer and i nearly lost 3 inches round my waste and it was only 30 quid.

best of luck mate
