Integrated eating has four developmental stages.

The first stage is Structured Eating: 

Structured Eating gives a form and organization to food and feeding. In this process an individual is given a structured or semi structured meal plan that includes balanced meals and snacks. Restoration of appetite and normal eating begins mechanically and the stomach and brain begin to communicate again. It may take several weeks or months before appetite returns.  However, without mechanical eating it is difficult to get back into the habit of eating again.
