The Claim

In adults with obesity and mild non-alcoholic fatty liver disease, a combination of alternate-day fasting and aerobic exercise for three months improves insulin sensitivity by 4% (QUICKI) and reduces insulin resistance by 2.55 units (HOMA-IR) compared to no intervention, but does not produce significantly greater improvements than alternate-day fasting alone or aerobic exercise alone.

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

In adults with obesity and mild fatty liver disease, combining alternate-day fasting with aerobic exercise for three months increases insulin sensitivity by 4% and lowers insulin resistance by 2.55 HOMA-IR units compared to no change, but the improvement is not greater than either intervention alone.

See the scientific wording

In adults with obesity and mild non-alcoholic fatty liver disease, combining alternate-day fasting with aerobic exercise improves insulin sensitivity by 4% (QUICKI) and reduces insulin resistance by 2.55 units (HOMA-IR) after three months, significantly more than no intervention, but not significantly more than fasting alone or exercise alone.

Why this might work

When the liver has less fat, it stops blocking insulin's signal, allowing the liver to take up sugar from the blood more effectively, which lowers blood insulin levels and improves how the whole body responds to insulin.

  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 for people with obesity and fatty liver, doing intermittent fasting and exercise together helps the body use insulin better — but doing just fasting alone works just as well. Exercise didn’t make it any better than fasting by itself.
