How many calories are in cheese pizza?
USDA numbers for regular-crust frozen cheese pizza, per package serving and per 100 g, with protein, fat and sodium.
Regular-crust frozen cheese pizza comes to 268 calories per 100 g, which is moderate per gram; the trouble is that a "slice" is not a unit. USDA package servings range from 81 g (about 217 calories) to 199 g for a whole 8 oz personal pizza (about 533 calories). Pizza is also one of the foods where the label serving is often small, so the number on the box rarely matches what you actually ate.

Is cheese pizza good for weight loss?
Cheese pizza can fit into a deficit if you control the slice count, since it does bring some protein, and 10.4 g per 100 g helps with fullness compared with sweet snacks. An 81 g serving at about 217 calories is a reasonable portion to pair with a salad; two of those is around 434 calories, which is a normal dinner for many people. The point where it goes wrong is eating half a pizza because it is already on the table. Decide on the number of slices before the pizza comes out of the oven, and plate them. Thin-crust versions and extra vegetables stretch the volume without adding much, while extra cheese and stuffed crusts do the opposite.
How to log cheese pizza in Cal.AI
For frozen pizza, Barcode is best: the box lists the serving weight, and you can use the minus and plus control to log two or three servings. For takeout, use Scan Food and then Fix Results to adjust the portion; an 81 g serving is a modest slice, while 146 to 151 g is a large one. The common mistake is logging one slice at the small package serving when your slice was closer to twice that weight.
Frequently asked questions
How many calories are in a slice of cheese pizza?
It depends on the slice weight. USDA package servings run from 81 g, about 217 calories, up to 146 to 151 g, about 391 to 405 calories, all at 268 calories per 100 g. A whole 8 oz personal cheese pizza weighs 199 g and has about 533 calories. Weigh one slice once to learn what yours is.
How much protein is in cheese pizza?
Frozen cheese pizza has 10.4 g of protein per 100 g, so an 81 g serving gives about 8.4 g and a 151 g serving about 15.6 g. That is more protein than most snack foods but less than a meat-based main. If you want the meal to hold you longer, a side with lean protein or a salad with beans helps.
Is cheese pizza high in sodium?
Moderately high. USDA lists 447 mg of sodium per 100 g, so an 81 g serving is about 362 mg and a 151 g serving about 675 mg. Eat the whole 199 g personal pizza and sodium reaches about 890 mg, over a third of the 2,300 mg daily limit in the Dietary Guidelines. Cheese and the crust both contribute, so toppings add on top of that.
