Protein intake on a ketogenic diet does not release the same amount of insulin as carbohydrate intake when glycogen is depleted and ketones are being produced.

“Lane will counter ketogenic claims by saying the amount of insulin released when you eat protein is the same as when you eat a carbohydrate and that is not true contextually dependent right that may be true on a mixed diet if we are using glycolytic metabolism if we are eating carbohydrates if we are if we are glycogen replete if we are not in a low carbohydrate state if we are not making ketones it may be true there are some studies which show that giving someone protein increases insulin to a similar degree as bread but in a ketogenic state on a low carbohydrate state that is not true”
