One extra-large slice is a 377-calorie meal
Costco's food court slices are big, and the figures reflect that. An extra-large slice weighs 139 g and carries 377 calories, about 19% of the daily calorie value. A large slice at 132 g lands at 358. The gap between the two sizes is small, so how many slices you eat matters far more than which size you get.
Stack slices and the total climbs fast. Two extra-large slices reach 753 calories, three hit 1,130, and five come to 1,883. Protein climbs too, from 30.1 g for two slices to 45.1 g for three, but so does every other row on the label, including fat and sodium.
If you are logging a food court lunch, the real decision happens at the second slice. One slice with a light side reads very differently from two slices on their own. BodyPal can log the slice from a photo, which helps when you are eating standing up next to the cart.
Carbs bring half the calories, fat over a third
Per 100 g, Costco pizza has 33.2 g of carbs, 10.5 g of fat and 10.8 g of protein. Turned into energy, carbs supply 49% of the calories, fat 35% and protein 16%. That is the classic thick-crust profile: the dough does most of the work, and the cheese brings much of the fat.
Saturated fat is 4.2 g per 100 g, and cholesterol is a modest 17 mg. Sugars stay low at 3.3 g per 100 g, or 4.6 g per extra-large slice. Fiber is thin as well, 2.2 g per 100 g and 3.1 g per slice, so the thick crust adds energy without adding much bulk.
Protein is respectable for fast food. One extra-large slice gives 15 g, which is 30% of the daily value, a bigger share than its 19% of daily calories. It still is not a protein-led food: for every gram of protein you get roughly three grams of carbs.
Sodium is the row to watch
Each extra-large slice carries 751 mg of sodium, which is 33% of the daily value. Calories for the same slice sit at 19% of their daily value. Sodium outpaces energy by a wide margin, and that gap is what sets this food apart from a home-style slice you might assume is similar.
Multiply and it gets serious. Two slices bring 1,501 mg, three bring 2,252 mg, and five reach 3,753 mg. Three slices alone land just under a full day's sodium daily value; five go well past it. Even a large slice at 713 mg uses 31% of the daily value.
If you watch sodium, the slice count is the lever that matters most. Potassium is only 169 mg per 100 g, so the slice offers little on that side of the ledger. Choosing water over a second slice, and keeping the rest of the day's meals less salty, leaves the most room to work with.
Treat a slice as a meal, not a snack
A single extra-large slice uses about 19% of the daily calorie value and 33% of the sodium value. That makes it a meal in its own right, not something to eat between meals. Log it that way, and plan the other meals around the sodium as much as the calories.
What the slice lacks is fiber and volume. At 3.1 g of fiber per slice, it leaves plenty of room for vegetables, fruit or a plain salad on the side, foods that add bulk without much salt. A side like that can make one slice feel like enough, which does more for the total than any topping swap.
These numbers are USDA values for a thick-crust cheese pizza from a restaurant or fast-food outlet, applied here to Costco's food court slice. Toppings change the picture: meat toppings generally push fat and sodium higher, so a combo or pepperoni slice will sit above the cheese figures on this page.
How does Costco pizza compare?
Here is how Costco pizza stacks up against cheese pizza, pepperoni pizza and generic pizza, per 100 g and per usual serving.
Verdict: Cheese pizza at 276 calories and generic pizza at 266 per 100 g bracket the Costco figure, so the source barely moves the calorie count. If sodium is your concern, skip pepperoni pizza at 759 mg and 291 calories per 100 g; for the fewest calories, plain pizza at 266 is the pick.
