The Claim
Aerobic exercise does not significantly improve fasting glucose, lipid levels, or liver enzymes in adults with nonalcoholic fatty liver disease over a 12-month period when dietary intake is not controlled.
What the research says
Supports is higher
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 adults with nonalcoholic fatty liver disease, 12 months of aerobic exercise does not change fasting glucose, blood fats, or liver enzyme levels if diet is not changed.
See the scientific wording
Aerobic exercise does not significantly improve fasting glucose, lipid levels, or liver enzymes in adults with nonalcoholic fatty liver disease over 12 months when dietary intake is not controlled.
When a person exercises regularly without changing what they eat, they lose body fat, especially around the belly. This fat loss reduces the amount of fat delivered to the liver, so the liver stores less fat. But this does not change the levels of sugar or fats in the blood after fasting, or the enzymes that show liver stress, because the liver's ability to process these substances stays the same.
What the research says
1 studyFor people with fatty liver, walking or jogging for a year can help reduce liver fat a little — but mostly because they lose some weight, not because exercise alone fixes everything. The study didn’t change diets, so it supports the idea that exercise alone isn’t a magic fix.
