CBL and CNS aren't a million miles from each other at all, but as SanosukeX mentions, the shakes on CBL aren't even a requirement, they can just give you a bit of help. There are more important aspects. It's more about understanding the principle of what to eat when essentially (and why), and how the body reacts to certain foods at certain times of day. Once you understand that, it all falls in to place really… just need to hit your macros and get good workouts in. 😉
