Few things: Carb cycling is just eating differing amounts of carbs on workout days than on non-workout days. Anything beyond that is people adding layers of shit to a simple concept. If you lift, more carbs, if you don't, less carbs. Pretty simple concept there, regardless with whatever random blogs you read talk about. And apparently you didn't even read that shitty blog you posted, because the guy says that an energy deficit, which is what we're talking about, is a part of leaning up, and on days where you lift you need more carbs. The simple biology is that unless you are in ketosis, fats and proteins provide energy at a substantially slower rate than carbohydrates. Which means unless you spend several hours in the gym at a go with lots of long breaks between sets, carbohydrates are your primary fuel source while lifting, which is what we're talking about. Energy in the gym.
Consuming carbohydrates after working out has absolutely -zero- impact on energy while in the gym, unless you go home and to sleep almost immediately and then lift in the morning when you wake up and you have replenished some of your glycogen stores. But again, since Dandai is specifically referencing lack of energy "in the gym" (going to keep highlighting that statement since you are arguing philosophy for "leangains" instead of what we are talking about) and without being in keto your fat and protein sources are a poor source of quick energy. To keep your energy up, in the gym, carbs being broken down in your system on top of a restored glycogen is what you need. Fairly simple biology here.
The funny part, is that Dandai also said he's not carb cycling, and consumes the same stuff every day regardless. Which makes when he consumes his carbs basically meaningless unless he only eats them at a specific time of the day instead spread out throughout the course. Which is precisely what I was talking about. I apologize for using the term "carb cycling" since it apparently has been attached to "leangains.", and I wasn't aware that it was a linked thing. My experience comes entirely from the gym and knowing a lot about the body; I don't read fitness blogs or reddit posts on the topic unless someone is linking them as scientific fact. Which that blog you posted states but doesn't actually spit out any science aside from anecdotal evidence. But hey, it is a blog, so there's that. When people talk about carb cycling in my experience, they usually mean consuming more carbs on lifting days than on non-lifting ones. Or they're doing something with ketosis.
I'm not going to call you slow, but I'm not sure what you're arguing about with post-workout philosophy from a lifting fad I haven't heard referenced in a real gym in over 20 years of lifting. And when I google "leangains"t, the first three links are two to the same website which uses the term "intermittent fasting" (and almost 100% guaranteed to be something retarded about skipping breakfast but eating a bigger lunch/dinner is "fasting") and reddit. So I'm sure it's a thing and pretty close to exactly what I referenced as "sounding like something from reddit."
And finally, I just noticed that you only partially quoted me about pre-workout shakes (I didn't say protein shakes)/supplements(you cut that out) so when I google "pre-workout shakes" I get alllllllll kinds of shit with sugar in it. Some are low/no sugar! But most of them have carbs in them. And while I'm pretty sure I can find protein powders designated for post or pre-workout that contain carbs, I'll give you that tiny victory. But the spirit of what I was saying (and I actually said it, you just snipped it up a bit) is still correct. A lot of that shit has grams of carbs mixed in with a tiny serving size, with the other chunk usually being caffeine/vitamins. Not a lot of fat or protein in them. But definitely carbs.
But anyway, just clarifying for you since you tried to straw man me and then took the low-road of being insulting. Also, again, Daindai was talking about energy in the gym. Not leangains, or post-workout muscle repair. Energy in the gym. Inside the building, working out(or time spent doing exercise as a generic term) and a lack of energy with his current diet plan. With the energy him not having directly being an issue during that time/in that place. For clarification purposes.
