How many slices of pizza are you?
A standard slice of pizza weighs about 110 g. A 75 kg adult equals roughly 682 slices of pizza — about 85 full pizzas, or three pizza nights for a small wedding.

The pizza calorie story
Your weight in pizza is more calorically dense than it sounds. A typical cheese slice supplies about 280 kcal — your body weight in pizza supplies roughly 190,000 kcal of food energy. That\'s 90+ days of normal eating at maintenance calories for an average adult. Pizza\'s calorie content comes mostly from the dough and cheese — toppings make a smaller difference than people assume.
