What's the best way of losing the weight quickly?
The best way is to combine lean protein (fish and poultry, which have a naturally low glycaemic index) with other low-GI foods and fat-burning superfoods. This will not only burn fat: it will also build muscle to replace the fat you lose. You don't eat any less and there's no calorie counting. Swap oily fish and fatty meat for lean fish and meat, eat low GI carbs and favour fat-burning superfoods. 

Obviously you're going to have to swap your steak for lean fish, your ordinary rice for basmati and your wholemeal bread for white,  but you'll soon see that little changes make a big difference.
