Patients should be served very small meals only (approximately 60g total per meal). Emphasis should be on high-protein foods and vegetables, with high-carbohydrate foods being secondary. Beverages and foods should not be ingested together. Patients must be educated to select no more than three items per meal from a selective menu.
