It is related that Umar bin al-Khattaab (radiallaahu anhu) said:

O people, beware of gluttony (excess) with respect to food, for it makes one lazy towards prayer, harms (corrupts) the body and makes (a person) inherit disease. However, it is upon you to have moderation in your nourishment, for it is nearer to rectitude, further away from excess and more fortifying for worshipping Allaah. And a servant does not perish until he prefers his desire (shahwah) over his religion.

And it is related that Abdullah bin Adiyy said:

Abdullah bin Umar used to have a freed slave, and once he returned from Iraaq. He came and gave salutations to him and said, "I have brought you a gift." He said, "And what is it?" He said, "Jawaarish." He (Ibn Umar) said, "And what is jawaarish?" He said, "It helps to digest food." He (Ibn Umar) said, "I have never filled my stomach (completely) with food for forty-years, so what am I going to do with it?"

Mawsoo'ah Ibn Abi al-Dunyaa (4/92) and Sifat al-Safwah (1/272) through Hayat al-Salaf of Ahmad al-Tayyar.
