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 protein does give you glucose, but it takes a long time, relatively speaking, for your body to get it. 1  When you eat carbohydrates, your pancreas secretes insulin, the hormone that enables you to digest starches and sugars. This release of insulin is sometimes called an insulin spike. Eating simple carbohydrates such as sucrose provokes higher insulin secretion than eating complex carbohydrates such as starch.
