I know you were being sarcastic.. but actually, if you follow a low carb diet (like he prolly does, maybe not.. not sure) it helps to eat shit carbs to spike insulin, and prime your insulin sensitivity say once a week or two. "Priming" the pump so to speak. Some people believe in this, some don't. I do, but it doesn't necessarily have to be shit carbs, it's just that it also just so happens to be a great time to splurge and relieve some of that craving for crap foods that you get. Two birds with one stone.
Yeah it was sarcastic but I'm honestly quite a big follower of the guy. He is on a low carb diet with an intake of something like 2500 calories a day, 100grams of carbs, 100grams of fat and 200grams of protein. He does intersperse it with 1 or 2 carb-up days a week though, so pretty much exactly what you said.
