The Claim

In overweight, sedentary adults with moderate dyslipidemia, aerobic exercise reduces liver fat as measured by increased liver density on CT scans and is associated with a 4.3 U/L reduction in alanine aminotransferase.

Source: Effects of aerobic vs. resistance training on visceral and liver fat stores, liver enzymes, and insulin resistance by HOMA in overweight adults from STRRIDE AT/RT.

In plain English

In overweight, sedentary adults with moderate dyslipidemia, aerobic exercise is associated with lower liver fat, measured by increased liver density on CT scans, and a 4.3 U/L decrease in alanine aminotransferase levels.

See the scientific wording

In overweight, sedentary adults with moderate dyslipidemia, aerobic exercise reduces liver fat as measured by increased liver density on CT scans, a finding not previously demonstrated in human trials, and is associated with a 4.3 U/L reduction in alanine aminotransferase, a biomarker of liver fat infiltration.

Why this might work

When a person does regular aerobic exercise, their body burns more energy, which causes fat stores to release fatty acids into the blood. These fatty acids travel to the liver, where they are burned for fuel instead of being stored. This reduces the amount of fat inside liver cells, making the liver denser on scans. As fat builds up less in the liver, the liver cells become less stressed and stop leaking a specific enzyme into the blood. At the same time, less fat in the liver and around internal organs improves how the body responds to insulin, which further stops the liver from making new fat.

  1. Study: Effects of aerobic vs. resistance training on visceral and liver fat stores, liver enzymes, and insulin resistance by HOMA in overweight adults from STRRIDE AT/RT.

    In overweight, inactive adults, walking or jogging regularly for 8 months reduced fat in the liver and lowered a blood marker of liver stress, as shown by CT scans and blood tests. Lifting weights didn’t have the same effect.
