The Prophet’s Guidance regarding Diet: The Prophet (peace and blessings of Allaah be upon him) used to know what he was eating.
He used to eat what was good for him.
He used to eat enough to keep him going, but no so much as to make him fat. Ibn ‘Umar narrated that the Prophet (peace and blessings of Allaah be upon him) said: “The believer eats in one stomach whilst the kaafir eats in seven.” Narrated by al-Bukhaari (5081) and Muslim (2060).
He taught his ummah something to protect them from diseases caused by eating and drinking. He said: “The son of Adam does not fill any vessel worse than his stomach. It is sufficient for the son of Adam to eat a few mouthfuls, to keep him going. If he must do that (fill his stomach), then let him fill one third with food, one third with drink and one third with air.” Narrated by al-Tirmidhi (1381), Ibn Maajah (3349); classed as saheeh by al-Albaani in al-Silsilah al-Saheehah (2265).
