The Claim

Alternate-day fasting alone reduces intrahepatic triglyceride content by 2.25% after three months in adults with obesity and mild non-alcoholic fatty liver disease, and this reduction is not statistically different from the 5.48% reduction achieved by combining fasting with aerobic exercise.

In plain English

In adults with obesity and mild non-alcoholic fatty liver disease, three months of alternate-day fasting reduces liver fat by 2.25%, a change that is not significantly different from the 5.48% reduction seen when fasting is combined with aerobic exercise.

See the scientific wording

Alternate-day fasting alone reduces intrahepatic triglyceride content by 2.25% after three months in adults with obesity and mild non-alcoholic fatty liver disease, a reduction that is not statistically different from the 5.48% reduction achieved by combining fasting with aerobic exercise, suggesting fasting alone may be sufficient for liver fat reduction in this population.

Why this might work

When a person eats very little every other day, the liver runs out of stored sugar and starts burning fat for energy instead. This process breaks down fat inside liver cells and turns it into fuel, which lowers the amount of fat stored in the liver. The body also becomes better at using insulin, which helps stop more fat from building up in the liver.

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

    This study found that eating very few calories every other day lowered liver fat just as much as doing that same diet plus exercising — so exercise didn’t add much extra benefit for reducing liver fat in these people.
