These fatty acids also can alter insulin signaling pathways and result in insulin resistance in hepatocytes and skeletal muscle cells, which may lead to diabetes. WebInterestingly, lipolysis (breakdown of fats to release fatty acids) and fat release from adipocytes is not different between untrained and trained people (Horowitz and Klein, 2000). This suggests that the improved ability to burn fat in trained people is attributed to differences in the muscle's ability to take up and use fatty acids and not ...
