You probably know someone who found out they had fatty liver disease during a routine check-up.
For many people, it shows up without a single warning sign. The question that follows is simple: what can I do about it?
A new meta-analysis published in October 2026 in Obesity Reviews pooled 16 randomized trials and found that long-term physical training was linked to a lower amount of fat stored in the liver.
Fatty liver disease, now often called MASLD, is far from rare. About 24 percent of US adults are affected, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

There is no approved drug aimed at the liver fat itself, which is why movement and diet carry so much weight here.
16 trials
The headline result is a drop in liver fat with regular training sustained over the long term.
Levels of ALT, a liver enzyme that often climbs when the liver is strained, also trended lower in the exercise groups, though the pooled change did not reach statistical significance.
Levels of AST, another common liver enzyme, did not improve.

The researchers also tried to nail down the ideal exercise dose. Their analysis of training frequency, intensity and duration ended up inconclusive, because too few trials covered each dose range.
In other words, movement clearly helps the liver, but this review alone cannot say exactly how much is best for every patient.
US guidance
The American Association for the Study of Liver Diseases offers more concrete numbers.
In its 2023 practice guidance, the group recommends 150 minutes of moderate exercise per week, spread over at least five days.

An increase of more than 60 minutes of activity per week on top of a sedentary routine also counts. For many people stuck at a desk, that puts the target within reach without a gym membership.
The guidance adds a point that often surprises patients. Exercise helps the liver even when the scale does not budge, with hepatic and cardiometabolic benefits seen independently of weight loss.
Workout routine
Brisk walking, cycling at a steady pace, swimming and similar moderate activity all count toward the weekly target.
Thirty minutes on five days matches the 150-minute goal almost exactly.

Anyone already managing liver disease, heart problems or diabetes should talk with a doctor before starting a new routine.
The pace, type and intensity that fit best vary from person to person, and the AASLD stresses that the plan should be tailored to each patient's ability and preferences.
