In the fourth and final phase of the gastric bypass diet you will graduate to solid foods without blending them
. Your portions will still be small, as they will always have to be, but hopefully at this point you will be starting to get use to the small meals. It is highly suggested that you continue to eat your food slowly and chew it thoroughly before ingesting it. These steps will greatly reduce the risks of bariatric surgery complications. After gastric bypass surgery you should stay clear of high fat and high in sugar foods. Your doctor will also have you take nutritional supplements or multi-vitamins to make up for the food that you cannot eat. You will need to take daily vitamins for the remainder of your life.
