For the first few days after bariatric surgery, an individual consumes primarily sugar-free liquids, according to Mayo Clinic. After a few days, an individual adds pureed foods, such as soft fruits and vegetables, eggs, lean ground meats and fish. Chopped solid foods are permissible after two months, but individuals must avoid fried foods, nuts and seeds, fibrous vegetables and tough meats.
The recommended diet for the two to six months after bariatric surgery should include at least six small meals with sufficient protein-rich foods to preserve muscle, advises the UCSF Medical Center. Individuals should attempt to obtain at least 65 to 75 grams of protein a day from foods such as poultry, fish, eggs, dairy and soy products. Daily caloric intake should not exceed 1,000 calories. Individuals must avoid bread, rice, high-fat foods and alcohol but should sip eight cups of caffeine-free liquids between meals every day. Individuals take daily high-potency multivitamin and mineral supplements, up to 2,000 milligrams of calcium, up to 1,000 International Units of vitamin D and 500 micrograms of vitamin B-12.
At the six-month post-surgical mark, an individual reduces her daily meals to three with one or two snacks, notes UCSF Medical Center. She increases food choices as tolerated, but she should not consume more than 1,000 calories per day.
