Lee believed that people should be aware of the nutrients they consumed on a daily basis. Within the pages of his script for Enter the Dragon, Lee made the following annotations about consuming only the calories your body actually needs, rather than simply indulging yourself in the culinary pleasures: "When you are a martial artist, you are a nut; you go to extremes to improve yourself as a marital artist. And one way is to eat only what your body requires and not get carried away with sensual [eating] pleasures." Lee also noted: "When you are a martial artist, you only eat what you require and don't get get carried away with foods that don't benefit you as a martial artist."
