Depends on your goals and where you currently are, the books (CBL and Carb Nite) explain how to use insulin to your advantage, I am not going to be able to explain in a forum post what took two books and hundreds of scientific studies to put together.
Generally if you follow a CBL protocol, you only consume carbs just after training, to assist your body to transport proteins into muscle cells when they are most receptive, in the morning fat cells are more likely to empty, as the hormonal balance of the body is set up to do so.
CBL is designed for people that already are pretty lean and is supposed to give you the final edge in maximising your natural gains and lean-ness. Carb Nite is more for people who still have a fair bit of fat to drop, both diets are designed to be done by people training with weights, not cardio bunnies, as it revolves around your weight training.
Like I said read the books and references and it's really quite simple to understand, also explains why other eating methods fail, and why some work.
Well you have to focus on when your body responds best to certain things, no point trying to fight what it does naturally, you can't argue away hormones and how they affect what goes on in your body
No one said CBL is a scientific refernece
What makes it a fad diet?? So any new scientific findings and research and development is a fad?? Have you read the books to be able to make this judgement and even comment on something that you clearly have no idea about. Unless you have read the books and followed up on the over 50 pages or scientific studies listed in the books as references you really are talking out of your arse, it would be like me telling you how to run a dairy farm, I have no idea, so I don't comment on it.
Well again refer to the book and around 50 pages of referenced scientific studies, then come back and comment on something you have educated yourself on. As only then you can make an educated and valid comment.
WTF??
Where did this gem come from?? Since when would building muscle require meats, grains and legumes and eaten together??
What benefits would the grains and legumes give you, pretty sure millions of people have build muscle without eating these three together. I personally pretty much never eat these together, so there for I should have no muscles??
