What does forest whitaker on color of money mean when he says do you think I need to lose some weight?

Answer 1

it is a reply to a repeated question ("Are you a hustler?") that he gets asked during the match by his opponent, Fast Eddie (Paul Newman). Part of the enjoyment of this film is trying to guess what is going through Eddie's mind at any given moment (Paul Newman won an Oscar for his performance). At this point, Eddie has just started to hustle alone again but he is older now and out of practice (at both the hustle and the game itself). He wins a few matches against some easy marks and then comes across Amos (Forest Whitaker). This is a critical scene in the film for several reasons. Eddie learns pretty quickly that Amos is trying to hustle him but he continues to lay down his money and let Amos run the table, saying: "Do it again". Eddie's pointed question: "Are you a hustler" is meant to intimidate Amos out of his twitchy, talky-guy routine. Eddie most likely thinks he can still outplay his younger, brash and overweight opponent. Amos does not answer Eddie's question until the very end of the match when he finally says the famous line: "Do you think I need to lose some weight?" The answer to both questions is of course: 'Yes'. The reason Amos answers him in this fashion is because a good hustler will always remain in character. Losing the match finally enables Fast Eddie to relinquish his own hustle and become a serious pool player again.
