In my guessing he's natural body type is thin or lean not beefy. Thats why he less sharing of workout activity in his insta (again my guessing). So for someone who naturally built lean, they only need to train to maintain the muscle without really pay attention on protein or calories they need to consume, since they only need to "maintain" not build

I would agree there. I think the real effort for him comes with bulking up, needing investment of time and a strict eating regime, stuffing yourself with extra protein and carbs. When he did it, he did it superbly, knowing exactly when to stop bulking. But who want to live that way all the time? It seems quite sane to me that he might want to spend some time being closer to his natural weight.
