The Claim

In adults with obesity and mild non-alcoholic fatty liver disease, a three-month intervention of alternate-day fasting combined with aerobic exercise does not significantly reduce alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood pressure, plasma lipids, or liver fibrosis scores, despite significant reductions in intrahepatic triglyceride content and improved insulin sensitivity.

Description
1 study reviewed
In plain English

In adults with obesity and mild fatty liver disease, three months of alternate-day fasting and aerobic exercise does not lower liver enzymes, blood pressure, blood fats, or liver scarring, even though liver fat and insulin sensitivity improve.

See the scientific wording

In adults with obesity and mild non-alcoholic fatty liver disease, alternate-day fasting combined with aerobic exercise does not significantly reduce liver enzymes (ALT, AST), blood pressure, plasma lipids, or liver fibrosis scores after three months, despite improvements in liver fat and insulin sensitivity, suggesting these markers are less responsive to short-term lifestyle intervention than intrahepatic triglyceride content.

Why this might work

When the liver burns more fat for energy, it clears out excess fat stored inside liver cells. This makes the liver more responsive to insulin, which lowers blood sugar. But the liver cells do not get less damaged or inflamed quickly enough to change the levels of liver enzymes or scar tissue markers in just three months.

  1. Study: Effect of alternate day fasting combined with aerobic exercise on non-alcoholic fatty liver disease: A randomized controlled trial

    In obese adults with fatty liver, combining intermittent fasting and exercise helped reduce liver fat and improve insulin sensitivity, but didn't lower liver enzymes, cholesterol, blood pressure, or fibrosis scores in just three months — meaning those other markers didn't budge even when the liver got less fatty.
