Insulin is an anti-catabolic hormone, not an anabolic one, and carbohydrate intake does not necessarily enhance muscle anabolism or strength.

“insulin affects mtor although it doesn't seem to be a powerful enough signal to actually impact muscle building if insulin has an effect it's probably more so on the protein breakdown side of things in fact there if you look at studies looking at carbohydrate ingestion we don't really see increases in muscle protein synthesis so if you just give pure carbohydrate even up to like 100 grams of glucose even though you get a pretty good rise in insulin it doesn't seem to affect muscle protein synthesis”
