If you don’t have the carbs as fuel then your body will convert fat into fuel to do that process. That’s what I was trying to say about converting fat into muscle.

I’m not strawmanning I think you’re moving the goalposts. You said mass gainers work. When I was on mass gainers I was easily getting over 5 calories. So I should be growing more muscle then right? Okay so if I push it to 6k calories, more muscle right? Or is there a threshold where you no longer see muscle gain and it’s all just fat? Make it make sense
