Hypothesis
Both exercise and omega-3 fatty acids would reverse or attenuate progression of NAFLD in obese rats, and the combination of treatments would have an even greater effect.
Conclusion
Exercise effectively treats hepatic steatosis in obese rats, while omega-3 fatty acids did not provide additional benefits and may have worsened liver fat accumulation.
Supporting Evidence
- Exercise lowered hepatic triglyceride levels in rats.
- Omega-3 fatty acids did not lower liver fat and may have increased it.
- Exercise improved insulin sensitivity in the rats.
- Rats receiving exercise had lower body fat percentages.
- Exercise increased complete fatty acid oxidation in the liver.
Takeaway
This study shows that exercise helps reduce fat in the liver of rats, but adding fish oil didn't help and might have made things worse.
Methodology
Male OLETF rats were divided into four groups and treated with exercise, omega-3 fatty acids, or both for eight weeks, after which various health metrics were assessed.
Potential Biases
Potential bias in the interpretation of results due to the specific dietary and exercise conditions applied.
Limitations
The study was conducted on a specific rat model, which may not fully represent human conditions.
Participant Demographics
Male OLETF rats, a model for obesity and metabolic syndrome.
