Abstract in brief

Acute exercise can quickly reverse insulin resistance caused by starvation, which typically develops after about 23 days due to increased lipid load.
One session of exercise boosts mitochondrial fatty acid oxidation, improves glucose tolerance, and enhances insulin sensitivity, despite reductions in glycogen stores and increased plasma free fatty acids.
The exercise-induced improvements are linked to changes in mitochondrial function, regulatory proteins related to glucose and fat metabolism, and increased activity of signaling pathways like Akt, aiding in better glucose disposal and lipid utilization.]
