You don't need a huge insulin spike to gain muscle. The carbohydrate my body is making from gluconeogenesis is likely enough to trigger an insulin / glut4 response. My glycogen stores are full as far as I am aware - I do not feel flat and typical glycolytic activity like 8 sets of 15 reps on squats are being achieved just as easily as when I was eating a lot of carbohydrateThere is this bro-science that you can't (or hardly can) gain muscles on a keto diet. Has to do with insulin response to carbs and whatnot. Wanna see if its true.
I think as long as glycogen stores are kept full there should be no issue with building muscle and muscle memory is giving me good strong gain so far. Bare in mind that my diet isn't "ketogenic". I may or may not be in ketosis I have no idea but that is not the point. The meat I am eating is typically 10-15% fat where as traditional ketogenic diets are 50-70% fat. I'm eating upwards of 400g of protein a day so there is likely a lot of gluconeogenesis going on to restore and add glycogen
