Fatty Liver and Sugar: How Much to Eat Per Day?

Note: This article is based on my personal experience and research. I am not a doctor or a dietitian, and this content is for informational purposes only. Always consult with your healthcare provider before making any changes to your diet or lifestyle.

After being diagnosed with a fatty liver, you might be tempted to believe that you should reduce the amount of fat you eat to reverse your condition. While this is a good starting point, it’s just one of the things you should do.

Another important one is cutting back on added sugar consumption – ideally, eliminating it completely from your diet, as sugar can be just as damaging, sometimes even more than fat itself.

Here’s what you should know:

Ideally, you should not consume any added sugar if you have fatty liver disease. Sugar equals empty calories that cause harm to your liver, so you should try to avoid it completely.

If that is not possible, aim to reduce it as much as possible. In grams, that would be 18 grams for men and 12 grams for women, based on the American Heart Association recommendations for healthy individuals (36 grams for men and 25 grams for women).

NOTE: This article does NOT refer to fatty liver and added sugar for those who also suffer from diabetes. In that particular case, the numbers could be completely different. Discuss this matter with your health provider instead.

So apart from completely eliminating alcohol from your diet, and keeping an eye on the types fats you consume, you also have to be very careful with the amount of added sugars you eat each day.

Why Sugar Matters as Much as Fat

Your body converts excess sugar and refined carbs into fat, which is stored in your liver, which is exactly the problem you’re dealing with when diagnosed with NAFLD/MASLD.

On top of that, added sugars spike your blood sugar, trigger insulin resistance, and cause inflammation. Over time, this worsens the condition and makes recovery harder.

You can read the article “The sweet danger of sugar” over at Harvard University for more details on why sugar is so bad for one’s health, even without the fatty liver diagnosis.

What Counts as “Added Sugar”?

Food companies sneak sugar into products under all sorts of names, not just “sugar”. Check out the ingredient lists for any of the names added sugar can have in processed producs:

• sucrose
• glucose
• fructose
• corn syrup
• malt syrup
• high-fructose corn syrup
• dextrose
• coconut sugar
• maple syrup
• honey

Since we are talking about added sugar, we should also stay away from some of the safer alternatives, like the final three listed above.

A rule of thumb: most ingredients ending in “-ose” are sugars. But not all are “added.” For example, lactose is naturally present in milk. Fructose is naturally foudn in fruit, but it’s also used as an additive in sodas and snacks.

So if you want to make sure that you only eat the things you should do, you should either prepare everything at home from base ingredients (which is difficult today), or read the labels carefully.

You’ll be surprised to see that sugar is added to products you’d never expect: deli meats and sausages (you should stay away from these anyway), bread, sauces, yogurt, etc.

Common Foods and Their Sugar Content

Companies are adding more sugar than they should to most foods (and even to some foods that don’t even need it). In most cases, cutting that amount to half would still deliver a tasty product.

But, to help keep things in perspective, here are some numbers you should consider:

Food/Drink	Sugar (grams)
12 oz can of Coke	35 g
Snickers bar	25 g
Flavored yogurt (1 cup)	18 g
Blonde Vanilla Latte (Grande)	35 g
Banana (medium, natural sugar)	14 g

That can of Coke or a Vanilla Latte (or anything similar) already puts you well over the safe limit for someone with fatty liver. Even the Snickers bar – which many people see as “just a small snack” – is more sugar than you should have in an entire day.

These are just a few examples – most store-bought foods and drinks have more added sugar than they should have.

Remember: we’re talking about added sugars, not the natural sugars found in fruits, vegetables, or whole grains. Those come with fiber, vitamins, and minerals that slow down absorption and actually help the liver.

A teaspoon of sugar stirred into coffee is not the same thing as the natural sugar in a banana (hence its presence in the chart above).

My Experience Cutting Sugar

When I was first diagnosed, I had a real sweet tooth. I always started my day with a coffee with two spoons of sugar and some creamer on top. Cutting that out felt impossible, but I did it. (By the way, here are some liver-friendly coffee creamer alternatives).

What worked for me was reducing slowly. Two spoons became one, then half, then eventually black coffee. Do this over the course of a month – don’t let it drag for too long, though.

These gradual changes will make the transition smoother. Just make sure you keep moving toward the goal, which is no added sugar at all (eventually).

I’ll be honest now: completely eliminating added sugar is very tough. But the closer you get to zero, the better your liver will be, and the healthier you will get.

I do agree that we need carbs from natural sources (our body needs them), but even those consumed in excess will have the same bad effects that plain sugar does. I personally ate fruits in moderation, and I was still able to reverse my condition.

Added sugar is not required in our diet, and our body simply does not need it: it serves no purpose whatsoever. It does make foods and drinks taste better, but otherwise, it’s just empty calories, because we get the required carbs from other food sources anyway (fruits, vegetables, and whole grains).

And there are solid options even when it comes to sweet snacks: check out my recommended liver-friendly dessert ideas here, or learn more about eating chocolate (and how it might help fatty liver).

(You can read one of the many articles on the topic of the uselessness of sugar on the NIH website here.)

And then we’ll have the sugar cravings that we’ll have to deal with. They are a real beast for most (myself included). But it is something that must be done if you want to get rid of your NAFLD.

Do fruits count as added sugar?

It’s actually recommended to have a diet rich in fruits and vegetables: despite the fact that they have a fair amount of sugars, they also have fibers, vitamins and minerals that help our body and liver, and are considered natural sugars that are absorbed slower, and therefore do less harm if any.

Not to mention the fact that our bodies have been consuming fruits for hundreds of thousands of years… so no, don’t even think about eliminating fresh fruit to reduce your sugar intake, as long as you don’t go overboard.

Dried fruits? Kiss them goodbye because they usually have added sugars (and some preservatives too).

Sure, you will need to eat fruit in moderation as well – two pounds of bananas each day, on top of a few pineapples and watermelons are definitely too much. But eating fruits as snacks and toppings without going overboard is definitely healthy and useful.

Remember: our body needs these sugars (carbs) for energy. It just doesn’t need added sugars or excess carbs.

Step-by-Step Sugar Reduction Plan Idea

While there are multiple approaches that will work, if you need some extra guidance, here’s how you can approach this:

• Day 1-2: Stop drinking sodas and fruit juices. Replace with water (or lemon water), sparkling water, or unsweetened tea.
• Day 3-4: Cut the sugar in your coffee/tea by half.
• Day 5-6: Swap desserts for fruit or plain yogurt with real cinnamon.
• Day 7: Start reading food labels, set a hard limit of less than 15 g added sugar per day (and try to get as close to 0 as possible).

Consider this as your personal challenge and understand that every small step you make will greatly impact the health of your liver, and your overall health.

It won’t be easy. Giving up on added sugar was my biggest challenge, but it’s doable. If I managed to do it, anybody can!

Conclusion

Fatty liver patients need to pay as much attention to sugar as they do to fat. While healthy adults may get away with 25–37 grams of added sugar per day, if you’re dealing with NAFLD, the safe zone is around 12–18 grams at most – and ideally zero.

Always opt for fruits when you feel the need to eat something sweet and learn to sweeten your foods with fruits also (use, for example, a banana instead of sugar when baking sweets).

And if you can’t really cut out all sugars overnight, take it slow, but make it your main goal to reduce sugar consumption drastically if you want to heal your liver.
