Obesity, which results from gluttony or chronic overeating, is against the will of God. The Bible condemns those whose "... god is their belly... " (Philippians 3:19). The Bible says that the body is the temple of God and that God will punish those who defile the body (1 Corinthians 3:16; 19-20). Exogenous obesity that occurs as a result of gluttony is evidence of willfully harming or defiling the body.

In 1 Corinthians 9:25,27 the Bible says, 'And everyone who competes for the prize is temperate in all things. Now they do it to obtain a perishable crown, but we for an imperishable crown. " {27} "But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified " God expects the christian to be master or controller over his or her own body, and not a slave TO the body. The Bible says that we become slaves to anything when we allow it to control us (Romans 6:16). This is true in many areas including overeating and gluttony.

In Ezekiel 16:49, the Bible says, "Look, this was the iniquity of your sister Sodom: She and her daughter had pride, fullness of food, and abundance of idleness; neither did she strengthen the hand of the poor and needy. " Evidently, one of the sins that brought Sodom to a depraved and sinful state was the gluttony and satisfaction of itself with food. Such can cause us to be obsessed with obeying the appetites of our flesh.

Similarly, Paul wrote of the inhabitants of the island of Crete, "One of them, a prophet of their own, said, "Cretans are always liars, evil beasts, lazy gluttons, " (Titus 1:12). Because the Cretans were this way Paul warned Titus that the work of preaching the gospel on the island of Crete would be a great challenge. Paul said that sometimes human beings, "... serve various lusts and pleasures... " (Titus 3:3). This is exactly what happens when a person fails to exercise self-control in eating and becomes a glutton or physically obese.

The Bible says that those who are gluttons or who are given to serving any lust of the flesh must have their whole orientation to the flesh changed through a renewing of the inner person (Galatians 5:16-24).
