I Googled "gluttony in the Bible" and found a very interesting website. Here's a little of it:
"Let your moderation be known unto all men. The Lord is at hand" (Philippians 4:5).
As Christians we are to realize the emphasis is to be put upon the spiritual man; however, just because we have an understanding of our spiritual position in Christ does not mean we can break His physical laws of health and not suffer the consequences. The spiritual man should always be given top priority as it needs to be in ascendancy. Its influence over the physical man is greater than the physical man's influence over it.We need proper balance between neglecting our bodies and giving them too much attention.
You can find the rest of it here.
