I've read the TNT book and (mostly) understand the concept but i'm curious how it would work with respect to gluconeogenesis. so on a low-carb diet, you want fat to be your body's primary fuel source. now if your diet is also rich in protein, it seems logical to me that your body would resort to gluconeogenesis quite readily since it wants to obtain glucose (assuming nothing in glycogen stores). is this what happens? Also, how does gluconeogenesis and glycogen storage coexist?
thanks!

This is what happens initially, which is why you can eat more protein the first couple of days. If you eat too much, then using fat as a primary source of fuel might not happen as you though it would. If you find that you are not losing or losing too slowly, you might want to see if your protein intake is too high. Your body will be making glucose for tissues that need it, hence you will have less available for storage.
