Is Butter Bad for Fatty Liver? Butter, Ghee and Better Fats
In large amounts, yes. Butter's fat is nearly two-thirds saturated, which raises liver fat more than unsaturated fat. Ghee is the same fat. Use a little.
TL;DR
- Butter isn’t banned with fatty liver, but a tablespoon has 7.3 g of saturated fat, more than a third of the FDA’s Daily Value, and saturated fat raises liver fat more than unsaturated fat in controlled trials.
- Ghee isn’t a healthier butter. It is the same butterfat with the water and milk solids removed, so a tablespoon has slightly more saturated fat and calories.
- Cook with olive, avocado or canola oil most of the time, and save butter for a teaspoon-sized finishing touch.
Butter is bad for fatty liver in the amounts many people use, though a small amount won’t undo a good diet. Nearly two-thirds of the fat in butter is saturated, the type that raised liver fat the most in controlled feeding studies, so for people with MASLD (formerly NAFLD) the goal is less butter and more unsaturated fat.
Here is what the research shows, how butter and ghee compare with other fats, and how to cook with less of them.
Why Does Saturated Fat Matter for a Fatty Liver?
The type of fat you eat changes how much fat your liver stores. Two Nordic trials tested this directly, and butter was part of both.
- Overfeeding study (Finland, 2018). Researchers gave 38 adults with overweight an extra 1,000 calories a day for three weeks. In the saturated fat group, the extra food each day was 40 g of butter (about 3 tablespoons), 30 g of coconut oil and 100 g of blue cheese. Liver fat rose 55% in that group, compared with 15% in a group eating extra olive oil, pesto, pecans and a little butter, and 33% in a group eating extra sugar. Saturated fat also increased insulin resistance and raised harmful fats called ceramides.
- Same calories, different fat (Sweden, 2012). In a 10-week trial, 67 adults with abdominal obesity ate diets with the same calories and the same total fat. One got its saturated fat mainly from butter, the other swapped in vegetable oils rich in polyunsaturated fat. Of the 61 who finished, liver fat was lower on the vegetable oil diet than on the butter diet.
Both trials were short, and they measured liver fat rather than long-term outcomes. But they point the same way: when butter replaces unsaturated fats, the liver tends to store more fat.
What Do Liver Guidelines Say About Butter?
None of the major guidelines bans butter by name. They focus on saturated fat:
- AASLD (2023): links eating saturated rather than unsaturated fat to a higher risk of steatohepatitis (MASH), and recommends, when possible, diets “with limited carbohydrates and saturated fat and enriched with high fiber and unsaturated fats (eg, Mediterranean diet).”
- EASL–EASD–EASO (2024): “Saturated fat has been shown to have a negative effect on liver steatosis in several short-term clinical trials.” It lists olive oil among the minimally processed foods to build meals around.
- NIDDK: recommends replacing saturated and trans fats with unsaturated fats, especially omega-3s.
The 2025–2030 Dietary Guidelines for Americans, written for the general public, say to prioritize oils such as olive oil when cooking, list butter as another option, and keep saturated fat to no more than 10% of daily calories. The liver guidelines lean harder toward unsaturated fat, and heart health is part of the reason: the AASLD notes that cardiovascular disease is one of the most common causes of death in people with fatty liver.
Is Ghee Better Than Butter for Fatty Liver?
No. Ghee is clarified butter. Butter is heated until its water cooks off and the milk solids can be removed, leaving almost pure butterfat. Taking out the water concentrates the fat, so ghee has slightly more saturated fat and calories per tablespoon than butter.
Ghee is central to many South Asian dishes and is popular for frying because it doesn’t burn as easily as butter. Neither of those changes its fat profile. There are no good human trials showing ghee is easier on the liver, so count it the same way you count butter.
How Does Butter Compare With Other Fats?
Here is a tablespoon of common fats side by side, sorted by saturated fat:
| Fat (1 tbsp) | Calories | Saturated fat | Share of 20 g Daily Value | Monounsaturated fat |
|---|---|---|---|---|
| Coconut oil (13.6 g) | 121 | 11.2 g | 56% | 0.9 g |
| Ghee (12.8 g) | 112 | 7.9 g | 40% | 3.7 g |
| Butter, salted (14.2 g) | 102 | 7.3 g | 36% | 3.0 g |
| Lard (12.8 g) | 115 | 5.0 g | 25% | 5.8 g |
| Whipped butter (9.4 g) | 69 | 4.3 g | 21% | 1.9 g |
| Olive oil (13.5 g) | 119 | 1.9 g | 9% | 9.8 g |
| Avocado oil (14 g) | 124 | 1.6 g | 8% | 9.9 g |
| Canola oil (14 g) | 124 | 1.0 g | 5% | 8.9 g |
| Mashed avocado, 2 tbsp (30 g) | 48 | 0.6 g | 3% | 2.9 g |
Source: USDA FoodData Central (SR Legacy). Ghee uses USDA’s anhydrous butter oil entry, which lists a tablespoon weight; USDA’s separate ghee entry gives a near-identical 60% saturated fat.
A few things stand out:
- Calories are similar across the board. Swapping butter for olive oil doesn’t save calories; it changes the type of fat. Whichever you choose, measure it.
- Olive and avocado oil have about a quarter of butter’s saturated fat and are mostly monounsaturated fat, the kind that raised liver fat least in the overfeeding study.
- Whipped butter spreads further, so a tablespoon carries about 40% less saturated fat than regular butter.
- Coconut oil is higher in saturated fat than butter, despite its healthy image.
How Much Butter Is OK With Fatty Liver?
There is no official butter limit for fatty liver. The numbers that matter are saturated fat totals: the FDA’s Daily Value is 20 g, and the Dietary Guidelines cap saturated fat at 10% of calories, about 22 g on a 2,000-calorie diet.
One tablespoon of butter uses up more than a third of that. One teaspoon has about 2.4 g of saturated fat and 34 calories, which is easier to fit. A sensible approach for most people with fatty liver:
- Use butter as a finishing touch, not a cooking fat. A teaspoon melted over vegetables or toast gives a lot of flavor.
- Count the hidden butter. Croissants, pastries, cookies, buttery restaurant sauces and movie-theater-style popcorn can carry more butter than you’d ever add yourself.
- Watch the stack-up. Butter, cheese and fatty meat in the same day add up quickly. Our guide to cheese and fatty liver shows how much each ounce adds.
An app like Liverly totals saturated fat across your meals, which makes it easier to see how much room is left for a pat of butter.
Better Swaps for Butter
| Instead of | Try |
|---|---|
| Butter to sauté vegetables or eggs | 1–2 teaspoons of olive or avocado oil |
| Butter on toast | Mashed avocado, hummus, or a thin layer of peanut butter |
| Ghee for curries and frying | Avocado or canola oil, with a teaspoon of ghee stirred in at the end for flavor |
| A butter sauce on fish or chicken | Lemon, garlic, herbs and a drizzle of extra-virgin olive oil |
| Butter in muffins and quick breads | A liquid oil, in recipes written for oil |
| Buttered popcorn | Air-popped popcorn with a light spray of oil and spices |
A few more habits help:
- Make olive oil your default. It anchors the Mediterranean-style diet both liver guidelines favor; see is olive oil good for fatty liver.
- Get more flavor per teaspoon. Brown butter, a little grated parmesan, toasted spices or fresh herbs give a rich taste with less fat.
- Choose nut butters for spreading. A peanuts-only butter brings mostly unsaturated fat; our peanut butter guide covers portions.
- Rethink the snack bowl. Air-popped popcorn needs very little fat to taste good; see is popcorn good for fatty liver.
What If You Have Cirrhosis?
Nutrition for cirrhosis is different from MASLD advice. The European guideline recommends a high-protein diet and a late-evening snack for people with muscle loss or decompensated cirrhosis, so the priorities differ from the advice above. Follow your hepatologist’s plan, and see our cirrhosis diet guide.
The Bottom Line
Butter is bad for fatty liver when it’s a daily cooking fat, and fine as an occasional small accent. Its fat is nearly two-thirds saturated, and in controlled trials saturated fat, including butter, raised liver fat more than unsaturated fats did. Ghee is the same fat in a more concentrated form, not a healthier version.
Cook with olive, avocado or canola oil, keep butter to about a teaspoon when you use it, and watch for the butter hidden in pastries and restaurant food. For how fats fit into the rest of your eating, see the fatty liver diet guide.

Frequently Asked Questions
Is ghee healthier than butter for fatty liver?
No. Ghee is clarified butter: the water and milk solids are removed, which leaves almost pure butterfat. That makes it slightly more concentrated, at about 112 calories and 7.9 g of saturated fat per tablespoon versus 102 calories and 7.3 g for butter (USDA). There are no good human trials showing ghee is better for the liver. Treat it exactly like butter and use it in small amounts.
How much butter can I have a day with fatty liver?
There is no official butter limit. The FDA's Daily Value for saturated fat is 20 g, and one tablespoon of butter has 7.3 g, more than a third of it. A practical approach is about a teaspoon at a time, around 2.4 g of saturated fat, used as a finishing touch rather than for cooking. Count it alongside cheese, fatty meat and baked goods.
Is margarine better than butter for fatty liver?
Soft tub spreads made from vegetable oils usually have far less saturated fat than butter: USDA lists about 1.7 g per tablespoon for a 60% fat tub spread versus 7.3 g for butter. Older stick margarines were a major source of trans fat, but the FDA no longer considers partially hydrogenated oils safe: for most uses, manufacturers had to stop adding them in 2018, with a final deadline of January 2021. Check the label for 0 g trans fat.
Is butter worse than sugar for fatty liver?
Both matter, and both are worth limiting. In a 2018 overfeeding study, an extra 1,000 calories a day for three weeks raised liver fat by 55% when the extra came mostly from saturated fat, including butter, and by 33% when it came from simple sugars. Sugar drove the liver to make new fat, while saturated fat had the bigger effect on liver fat overall. Unsaturated fat raised it least.
