The Claim

In diabetic obese patients with nonalcoholic fatty liver disease, 8 weeks of supervised aerobic exercise (either high-intensity interval or moderate-intensity continuous) significantly reduces alanine aminotransferase (ALT) levels, independent of weight loss.

Cause and effect
1 study reviewed
In plain English

In obese adults with type 2 diabetes and fatty liver disease, 8 weeks of supervised aerobic exercise lowers liver enzyme levels without requiring weight loss.

See the scientific wording

In diabetic obese patients with nonalcoholic fatty liver disease, 8 weeks of supervised aerobic exercise (either high-intensity interval or moderate-intensity continuous) significantly reduces alanine aminotransferase (ALT) levels, suggesting improved liver enzyme profiles independent of weight loss.

Why this might work

When a person exercises, their muscles burn more fat for energy, which pulls fat out of the bloodstream. With less fat circulating, the liver receives less fat to store. As a result, the liver accumulates less fat, which allows it to function better and release fewer liver enzymes into the blood.

  1. Study: Effects of high-intensity interval and moderate-intensity continuous aerobic exercise on diabetic obese patients with nonalcoholic fatty liver disease

    This study found that both intense and moderate exercise for 8 weeks reduced fat in the liver of people with type 2 diabetes and obesity—even without losing weight. Less liver fat usually means lower liver enzyme levels, so the exercise likely helped the liver heal.
