His opinion backed by nothing, he is ignoring all science and research done by others IMO.
His way will work for some people, but not all, I believe different things will work for different people.
For example I used to train with a guy years ago, we used to train the exact same split for about 12 month, 4 times a week religiously, many years ago.
He was eating Maccas for breakfast, KFC or huge take away shop burger for lunch with serving of chips and coke, and whatever he wanted for dinner, ranging from pizza to ice cream, on top he used to have TWO 2000 Calorie weight gainer shakes per day, that's 4000 calories of shakes alone, and beers several nights a week. Nil Cardio.
He was ripped as, I am talking ultra ripped with every muscle visible, abs, the lot.
I was doing the same training eating a lot less carbs and still looking soft till I started cutting carbs, so his diet worked for him, if I followed his diet I would be a 200kg marshmellow
So every person needs to find the diet that works, calorie counting does not work for me, and I hate life when ever I do it.
Eating low carbs again and definition is starting to show and body fat is dropping off. I am at the moment following a low carb diet with a refeed day once a week, eating carbs at night only one night a week after a HEAVY training session, usually after Squat or Dead Lift day.
Will stick with that as it works for ME and I find it easy to do, as I can delay any carb cravings till the refeed day, and organise it around my social life IE going out for dinner with friends or family, parties etc. So I feel I am not missing out.
So I do not believe there is one diet for all people.
Might give the whole CBL a run once I drop another 5 or 6 kg, and see how it works for me, but I am not sure I could actually eat that many carbs every night, I prefer the meals I am having now, as they are very satisfying and tasty
