The Study
Single Bout Of Aerobic Exercise Reduces Intrahepatic And Intramyocellular Triglyceride In Obese Individuals With Nafld: 3187 Board #252 June 3, 2: 00 PM - 3: 30 PM.
This study watched 10 people exercise once and saw their liver and muscle fat go down a little right after. But it didn't compare them to people who didn't exercise, so we don't know if the workout actually caused the drop or if something else did.
Analysis score

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — even one short workout can temporarily lower fat levels in the liver and muscles of people with fatty liver disease.
- 2After one 30-minute walk at a moderate pace, liver fat dropped from 16% to 14.2%, and muscle fat dropped from 2.2% to 1.3%.

People with non-alcoholic fatty liver disease who perform 135 minutes of aerobic exercise each week have lower levels of fat in their liver compared to those who do not.
In obese adults with non-alcoholic fatty liver disease, a 30-minute aerobic workout at half their maximum oxygen capacity is linked to a measurable drop in fat stored in the liver and muscle cells right after the exercise.
