true, but gluconeogenisis is metabolically inefficient (and very very cost $ inefficient ,, meaning protein is way more expensive then carbs just to use as glucose) ,, I know of some guys that are on keto and they just slam 40 grams of dextrose or some fast acting carb pre-workout and get some of the benefits of glucose, but they have such a high work load and intensity that they burn through it and get back into ketosis in a couple hours.
