The Claim

In adults with obesity and mild non-alcoholic fatty liver disease, a combination of alternate-day fasting (600 kcal on fast days) and five weekly sessions of moderate-intensity aerobic exercise (60 minutes per session) reduces intrahepatic triglyceride content by 5.48% after three months, which is a significantly greater reduction than that observed with exercise alone (1.30%) or no intervention (0.17%).

Cause and effect

In plain English

In adults with obesity and mild fatty liver disease, combining a low-calorie fasting schedule with regular moderate exercise reduces liver fat by 5.48% after three months, which is more than exercise alone or no treatment.

See the scientific wording

In adults with obesity and mild non-alcoholic fatty liver disease, combining alternate-day fasting (600 kcal on fast days) with five weekly sessions of moderate-intensity aerobic exercise (60 minutes per session) reduces intrahepatic triglyceride content by 5.48% after three months, a significantly greater reduction than exercise alone (1.30%) or no intervention (0.17%), indicating that the combination therapy is more effective than either component alone for reducing liver fat.

Why this might work

When a person eats very little every other day and exercises regularly, the liver runs out of stored sugar and starts burning fat for energy instead. This process clears fat out of the liver, while better insulin signaling stops the liver from making new fat. Together, these changes reduce liver fat more than either change alone.

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

    For people with obesity and mild fatty liver, doing a mix of eating very little every other day and exercising five times a week cuts liver fat much more than just exercising or doing nothing. The study proves this combo works better than either one alone.
