The insulin spike didnât even increase muscle blood flow! What appears to have happened was, because they used a protein source (whey) that has already been shown to maximally stimulate post-exercise protein synthesis as well as increase insulin levels, no further anabolic effect was possible even from an insulin spike.
And, thatâs how scientists found that elevation of fat levels in the blood âcauses insulin resistance by inhibition of glucose transportâ into the muscles. And, this can happen within just three hours. One hit of fat can start causing insulin resistance, inhibiting glucose uptake after just 160 minutes.
