All that cheese is not good news for pizza lovers to start with. Then many of us add any number of toppings that are high in fat. Just eating half a plain margherita pizza from Pizza Express gives you 263 calories. A single slice of Dominos deluxe has 171 calories. If you cant resist the odd pizza now and then, try going for the lower fat toppings such as vegetables and prawns. Dont ask for extra cheese and avoid garlic dips or garlic bread. Contrary to what you might think, the deep pan pizza is actually a healthier option than the thin crust as it contains less fat.
