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.
This is because the beta cells of the pancreas are unable to provide enough insulin to keep the blood sugar levels in the normal range. When people with diabetes find their blood sugar level to be unexpectedly high, they might call it a spike. This typically happens after eating a rich meal or a sequence of rich meals. by rich I mean high in starch and/or sugar plus animal fat. The starch/sugar raise the blood sugar, and the fat helps keep the sugar levels high by blocking the insulin from working efficiently. Pizza, ice cream, pasta with butter, etc.
