The Claim
The reduction in intrahepatic triglyceride content resulting from aerobic exercise in adults with nonalcoholic fatty liver disease is primarily mediated by weight loss, as the direct effect of exercise on liver fat becomes statistically nonsignificant when weight loss is adjusted for.
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, aerobic exercise reduces liver fat primarily because it leads to weight loss; when weight loss is accounted for, exercise no longer shows a direct effect on liver fat levels.
See the scientific wording
The reduction in intrahepatic triglyceride content from aerobic exercise in adults with nonalcoholic fatty liver disease is largely mediated by weight loss, as adjusting for weight loss eliminates the statistical significance of exercise’s direct effect on liver fat in most cases.
When a person exercises regularly, they burn more calories and lose body fat, especially around the abdomen. This fat loss means fewer fatty acids flow into the liver. With less fatty acid coming in, the liver makes less new fat and burns more of what it already has, so fat builds up less in the liver.
What the research says
1 studyWhen people with fatty liver exercise and lose weight, their liver gets better mostly because they lost weight, not because exercise magically cleans the liver on its own. This study shows that once you account for the weight loss, exercise alone doesn’t make much difference.
