Is Pizza Bad for Fatty Liver? Slices, Crusts and Better Toppings

TL;DR

• Pizza isn’t banned with fatty liver, but typical takeout pizza stacks a refined crust, cheese high in saturated fat, processed meat and a lot of sodium.
• One slice of a national chain’s 14-inch pepperoni pizza has about 320 calories, 5.9 g of saturated fat and 835 mg of sodium. In CDC data, only deli meat sandwiches supply more of the sodium Americans eat.
• Keep it to one or two slices with a big salad, choose vegetable toppings and lighter cheese, or make it at home on a whole-wheat crust.

Pizza isn’t bad for fatty liver as an occasional meal, but the usual takeout version comes close to a checklist of what liver guidelines ask you to limit. For people with MASLD (formerly NAFLD), a couple of slices now and then is fine; a few slices several times a week, with breadsticks and soda, works against the liver fat you’re trying to lose.

Here’s what makes pizza a problem, how different pizzas compare, and how to build a slice that fits your plan.

Why Is Pizza a Problem for Fatty Liver?

Take a slice apart and each layer raises a different flag.

The crust: refined carbohydrates. Most pizza dough is white flour. The AASLD’s 2023 guidance notes that a diet with excess calories, “particularly excess saturated fats, refined carbohydrates, and sugar-sweetened beverages,” is associated with obesity and NAFLD. A hand-tossed chain slice has about 35 g of carbohydrate and only 2.5 g of fiber in USDA data. Our guide to bread and fatty liver covers why refined flour matters.

The cheese: saturated fat. In a controlled feeding study, extra saturated fat raised liver fat more than the same calories from sugar or unsaturated fat. The AASLD links saturated fat, more than unsaturated fat, to a higher risk of steatohepatitis. Cheese is a concentrated source: in USDA data, low-moisture whole-milk mozzarella has about 4.4 g of saturated fat per ounce and part-skim about 3.2 g (see is cheese bad for fatty liver).

The toppings: processed meat. In a 2018 study of 789 adults in Israel, people who ate more red and processed meat had 47% higher odds of fatty liver and higher odds of insulin resistance, even after accounting for body weight, saturated fat and other factors. It was a cross-sectional study, so it shows a link rather than cause, but it’s one reason pepperoni and sausage are worth limiting. Our guide to red meat and fatty liver has more.

The salt. A 2026 CDC analysis of national survey data (2021–2023) found that pizza supplies 4.4% of all the sodium Americans eat, behind only deli meat sandwiches (5.0%) and tied with savory snacks and soups. Too much sodium raises blood pressure, and the Dietary Guidelines set the limit at less than 2,300 mg a day (see is salt bad for fatty liver).

The 2024 European MASLD guideline (EASL–EASD–EASO) recommends “limiting the consumption of ultra-processed food (rich in sugars and saturated fat),” and the NOVA classification used in nutrition research counts pre-prepared pizza dishes as ultra-processed.

What Does Research Say About Pizza and Fatty Liver?

No study has looked at pizza on its own, but research on fast food points the same way. A 2023 study from Keck Medicine of USC, published in Clinical Gastroenterology and Hepatology, analyzed about 4,000 adults in the 2017–2018 National Health and Nutrition Examination Survey. It counted meals, including pizza, from a drive-through restaurant or one without wait staff as fast food.

• Getting 20% or more of daily calories from fast food was linked to higher liver fat.
• The rise was moderate in the general population and much larger in people with obesity or diabetes.

This was an observational snapshot, so it can’t prove that fast food caused the liver fat. But it suggests that the problem is fast food as a regular part of the diet, not an occasional slice.

How Do Different Pizzas Compare?

Here’s one slice of several common pizzas. The chain values are USDA’s analysis of 14-inch pizzas from one national chain, so the crusts can be compared directly:

Pizza (1 slice)	Calories	Carbs	Saturated fat	Sodium
Frozen cheese, thin crust (69 g)	181	19.9 g	3.9 g	325 mg
Chain cheese, thin crust (79 g)	242	27.0 g	4.8 g	677 mg
Chain cheese, hand-tossed (105 g)	289	35.1 g	5.1 g	708 mg
Chain cheese, pan crust (112 g)	309	36.8 g	4.9 g	650 mg
Chain pepperoni, thin crust (80 g)	266	26.1 g	5.3 g	774 mg
Chain pepperoni, hand-tossed (110 g)	320	35.3 g	5.9 g	835 mg
Chain sausage, hand-tossed (119 g)	342	35.0 g	6.5 g	798 mg
Chain “supreme,” hand-tossed (123 g)	305	32.0 g	5.2 g	809 mg

Source: USDA FoodData Central (SR Legacy). Recipes and slice sizes differ between brands.

What the numbers show:

• Sodium adds up fast. Every chain slice has 650–835 mg. Two hand-tossed pepperoni slices come to about 1,670 mg, roughly 73% of the 2,300 mg daily limit in the Dietary Guidelines.
• Thin crust cuts carbs, not saturated fat. Thin-crust slices have about 8–9 g fewer carbs and about 50 fewer calories, partly because they’re smaller. Saturated fat and sodium change much less.
• Meat toppings add saturated fat. Sausage has the most saturated fat per slice here, at 6.5 g, about a third of the FDA’s 20 g Daily Value.
• Frozen pizza varies. A thin-crust frozen cheese slice is small and relatively light, but USDA’s frozen thick-crust meat pizza has 876 mg of sodium per slice, so compare labels per serving.

How to Make Pizza Fit a Fatty Liver Diet

There’s no official pizza limit. One or two slices as part of a meal, not the whole meal, is a sensible place to start.

Ordering out:

• Start with a salad. Eat a large salad with an olive oil dressing first, then have your slices.
• Pick vegetable toppings. Mushrooms, peppers, onions, spinach, tomatoes and artichokes add fiber and volume for very few calories.
• Choose chicken over pepperoni or sausage if you want meat.
• Ask for light cheese rather than extra.
• Go thin if you like it, knowing it mainly trims carbs.
• Skip the extras. Breadsticks, garlic butter, dipping sauces and stuffed crusts add calories, fat and salt.
• Drink water. Sugary drinks are one of the clearest dietary drivers of fatty liver (see is soda bad for fatty liver).

Making it at home:

• Use whole-wheat dough or a whole-wheat pita or flatbread as the base.
• Use part-skim mozzarella, and add a little grated parmesan for flavor.
• Check the sauce label: canned pizza sauce has about 220 mg of sodium per quarter cup in USDA data, so a low-sodium sauce or plain crushed tomatoes with herbs helps.
• Pile on vegetables and finish with a drizzle of olive oil.

If you want to see how a slice stacks up against the rest of your day, an app like Liverly can score the meal for saturated fat, sodium and refined carbs.

Better Pizza Swaps

Instead of	Try
Pepperoni or sausage	Grilled chicken or extra vegetables
Extra cheese	Regular or light cheese
Pan or deep-dish crust	Thin or whole-wheat crust
Three or four slices	One or two slices plus a large salad
Breadsticks and soda	A side salad and water or sparkling water
A frozen meat-lovers pizza	A homemade whole-wheat flatbread with vegetables

What If You Have Cirrhosis?

Cirrhosis changes the priorities. People with fluid buildup (ascites) are usually asked to cut sodium further: European nutrition guidance puts the target at about 2 g of sodium a day, so a single hand-tossed pepperoni slice would use over 40% of it. At the same time, getting enough protein and calories matters more than it does with MASLD alone. Follow your hepatologist’s plan, and see our cirrhosis diet guide.

The Bottom Line

Pizza isn’t bad for fatty liver as an occasional meal, but typical takeout pizza combines a refined crust, saturated fat from cheese, processed meat and a lot of sodium. Research links fast food that makes up a fifth or more of daily calories to higher liver fat, especially in people with obesity or diabetes.

Keep it to one or two slices with a big salad, pick vegetables over pepperoni and sausage, go easy on the cheese, and drink water. Homemade pizza on a whole-wheat crust gives you the most control.
