This is all about a relationship with God. A controlling person has a relationship with themselves. They know every detail about themselves, and their mind is constantly returning to thinking about what they need. Their mouths and conversations will invariably return to talking about themselves and their wants, their needs, their desires. With each passing year, the dieter is more in love with the food and less in love with God. The relationship with God cannot proceed until the control is laid down. The control leads to dieting, which leads to greed, and the greed leads to being out of control. You only have one thing to concentrate on, you only have one thing to do, and that is to concentrate on your relationship with God.
