Inside a super giant infinite castle that seemed like a void.

Is where the worlds most gluttonous king lives, with oceans and voids of servants who serves him 100,000 to 500,000 calories worth of junk food everyday. He keeps doing this, not knowing how bad is for him and his organs and body is starting to weaken from this, until he could not stand and kept sitting on the huge throne inside the infinite void castle, filled with infinitely expansive pillars, and oceans of servants filling him with junk food to fill up his appetite.

There was absolute infinite servants, but it only filled a quarter of the infinite void castle, you could tell him what he is doing is bad for his health and body or leave him to eat to death.

What do you do?
