Fatty liver is reversible in most cases, and the path to healing it is well established: lose a moderate amount of weight, change what you eat, and move more. Losing just 3 to 5 percent of your body weight can measurably reduce liver fat, while losing 7 percent or more can also reduce the inflammation that pushes the disease toward scarring. For someone weighing 200 pounds, that’s 6 to 14 pounds. Most doctors recommend reaching that 7 to 10 percent loss gradually over the course of a year.
Why Weight Loss Is the Most Effective Treatment
No single food or supplement heals a fatty liver as reliably as losing weight. Your liver accumulates fat when it takes in more energy than it can process, and shedding even a small percentage of body weight reverses that equation. At the 3 to 5 percent mark, you’ll see reduced fat in the liver on imaging. At 7 percent, inflammation starts to resolve. At 10 percent, there’s evidence that even early-stage scarring (fibrosis) can improve.
Crash diets aren’t the goal. Rapid weight loss can actually worsen liver inflammation temporarily, and it’s rarely sustainable. A calorie-restricted approach in the range of 1,200 to 1,800 calories per day, depending on your sex and size, is what most clinical trials use successfully. The emphasis should be on steady, sustained loss rather than speed.
What to Eat: The Mediterranean Approach
The dietary pattern with the strongest evidence behind it is the Mediterranean diet, built around vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish, with minimal red and processed meat. In one well-designed trial published in the journal Gut, participants following a standard Mediterranean diet lost about 20 percent of their liver fat over 18 months. A modified “green Mediterranean” version, which added green tea (3 to 4 cups daily) and a daily plant-based shake rich in polyphenols while further cutting red and processed meat, nearly doubled that result, with a 39 percent reduction in liver fat, even though both groups lost similar amounts of body weight.
Walnuts appeared to play a specific role. Both Mediterranean groups ate about 28 grams (a small handful) of walnuts daily, and higher walnut intake was independently linked to greater liver fat loss. The takeaway: the type of food you eat matters beyond the calorie count. Polyphenols, the plant compounds found abundantly in green tea, walnuts, berries, and leafy greens, appear to directly benefit liver fat metabolism.
Cut Back on Sugar, Especially Liquid Fructose
Fructose is uniquely harmful to the liver compared to other sugars. While glucose gets metabolized throughout your body, fructose goes almost entirely to the liver, where it bypasses the normal checks that regulate how much fat your liver produces. It essentially floods the liver with raw material for making new fat. Worse, when this fat-production pathway is running at full speed, it also blocks the liver’s ability to burn existing fat for energy. It’s a double hit: more fat made, less fat burned.
The biggest sources of excess fructose are sugary drinks, including sodas, fruit juices, sweet teas, and energy drinks. Whole fruit is fine because the fiber slows absorption and the amounts are modest. But a single can of soda can deliver more fructose in minutes than your liver is designed to handle. Eliminating or sharply reducing sugary beverages is one of the highest-impact changes you can make.
Exercise: What Type and How Much
Both aerobic exercise (walking, cycling, swimming) and resistance training (weights, bodyweight exercises, resistance bands) reduce liver fat with roughly equal effectiveness. The protocol that works in most studies is straightforward: 40 to 45 minutes per session, three times per week, for at least 12 weeks. You don’t need to be gasping for air. Moderate intensity, the equivalent of a brisk walk or light jog, is enough for aerobic sessions. Resistance training at a moderate effort level works just as well.
Exercise reduces liver fat even in studies where participants don’t lose significant weight, which means physical activity has a direct benefit on liver metabolism independent of the scale. That said, combining exercise with dietary changes produces the best outcomes. If you’re currently sedentary, starting with any regular movement and building toward those targets over several weeks is a reasonable approach.
Coffee May Help
Regular coffee consumption is consistently associated with lower rates of fatty liver disease and reduced liver scarring. A dose-response meta-analysis found that drinking more than three cups per day significantly reduced the risk of fatty liver, and people who drank coffee regularly had lower levels of liver enzymes (a marker of liver stress) compared to non-drinkers. The benefit appears to come from coffee’s bioactive compounds rather than caffeine alone, though both filtered and unfiltered coffee show protective effects. Coffee isn’t a treatment on its own, but if you already drink it, there’s good reason to keep going.
Sleep and Liver Fat
Short sleep contributes to liver fat accumulation, particularly when combined with excess body weight. Research shows that sleep duration is meaningfully connected to liver fat levels, and that up to 39 percent of the relationship between body fat distribution and liver fat may be explained by how much someone sleeps. Poor sleep drives insulin resistance, increases appetite hormones, and raises cortisol, all of which push the liver toward storing more fat. Aiming for 7 to 8 hours of consistent, quality sleep supports every other change you’re making.
Understanding Your Diagnosis
If your doctor has used a FibroScan or similar imaging tool, you may have received a CAP score, which measures how much of your liver contains fat. Here’s what those numbers mean:
- 238 to 260 dB/m (Grade S1): Less than one-third of your liver is affected. This is mild fatty liver.
- 260 to 290 dB/m (Grade S2): Between one-third and two-thirds of your liver is affected. Moderate fatty liver.
- 290 to 400 dB/m (Grade S3): More than two-thirds of your liver is affected. Severe fatty liver.
All three grades are still reversible with lifestyle changes, especially S1 and S2. Your doctor may also measure liver stiffness to check for fibrosis (scarring), which is the more serious concern. Simple fatty liver without inflammation or scarring has an excellent prognosis when addressed early.
When Medication Enters the Picture
For most people with fatty liver, lifestyle changes are the entire treatment plan. But in 2024, the FDA approved the first medication specifically for fatty liver disease that has progressed to moderate or advanced scarring (fibrosis) with inflammation, a stage sometimes called MASH. The drug, resmetirom (brand name Rezdiffra), is intended for use alongside diet and exercise, not as a replacement. It’s specifically for people who haven’t yet developed cirrhosis but whose liver disease has advanced beyond what lifestyle changes alone may reverse quickly enough.
If your fatty liver was caught at the simple steatosis stage, without significant inflammation or fibrosis, medication isn’t typically part of the conversation. The lifestyle strategies above are your primary tools, and they’re remarkably effective. In the green Mediterranean diet trial, the percentage of participants who still qualified as having fatty liver disease dropped from a baseline rate down to just 31.5 percent over 18 months, driven entirely by diet, exercise, and moderate weight loss.
