Patients eat no food for the first day or two after surgery, explains Mayo Clinic. For the next few days, they are only allowed to have liquids and semisolid foods, such as broth, juice, milk, soup and gelatin. Pureed foods, such as lean meats, eggs, beans, soft fruits and vegetables, are introduced for the next two to four weeks. Soft foods are then reintroduced. After about eight weeks, solid foods with firmer textures are allowed.

Foods to avoid in the weeks after surgery include nuts and seeds, popcorn, dried fruits, carbonated beverages and granola, advises Mayo Clinic. It is also best for patients to avoid fibrous vegetables, tough meats and breads.

Eating six small meals throughout the day is recommended, notes MedlinePlus. Taking 20 to 30 minutes to eat each meal while chewing thoroughly is important to ensure that food passes through the opening between the new, smaller stomach pouch and the intestines. Patients should not consume beverages with meals or for 30 minutes after eating, and they should stop eating as soon as they feel full.
