And put a knife to your throat, if you have a strong desire for food.
Matthew 18:8-9

1 Corinthians 9:27
But I give blows to my body, and keep it under control, for fear that, after having given the good news to others, I myself might not have God's approval.
Philippians 3:19
Whose end is destruction, whose god is the stomach, and whose glory is in their shame, whose minds are fixed on the things of the earth.
