A gastric bypass is a surgical procedure designed to promote weight loss by reducing the size of the stomach, making it difficult to eat large quantities of food. Not only do you have to eat less after the surgery, but you also may need to change the types of foods you eat and how you eat them. The gastric bypass diet includes foods high in protein, low in fat, sugar and calories. It is important to carefully plan meals after gastric bypass surgery to make sure you get all your nutrient needs.
Immediately following surgery your diet is limited to just liquids, after a few days you can introduce pureed foods, then advance to semi-solid, soft foods. Finally, after eight weeks you can start eating solid food again. No matter what stage of the diet you are on, it is important to eat slowly and introduce new foods one at a time. At eight weeks, the size of your stomach should be about 1/2 cup. Aim for three meals a day and focus on protein foods. Your goal is to eat about 60 g of protein a day, according to the University of Virginia Healthsystem. A solid food breakfast for gastric bypass patients may include one egg scrambled in cooking spray with 1 oz. of fat free cheese. You can also try a 1/4 cup serving of fat free cottage cheese or fat free, sugar-free yogurt with 1/4 cup of canned fruit.
Foods high in fat take the stomach longer to digest, which may make you feel uncomfortable. Choose lean sources of protein to limit your intake of fat, such as skinless poultry, fish and lean red meat. Foods high in sugar can lead to dumping syndrome. Dumping syndrome occurs when undigested food is dumped into the small intestines leading to abdominal pain and diarrhea. A low-fat, low-sugar lunch for the gastric bypass patient may include 3 oz. portion of canned tuna packed in water with 1/4 cup of steamed green beans and and two low-fat crackers. You can also try 3 oz. of lean luncheon meat -- choose 95 percent fat free luncheon meats -- with 1/4 cup of diced melon.
Gastric bypass patients should drink fluids in between meals to avoid feeling too full at meal times. Gastric bypass patients should drink 6 to 8 cups of fluid a day, according to the University of Virginia Healthsystem. Choose sugar-free, non-carbonated beverages such as water, sugar-free drink mixes, sugar-free iced tea and skim milk. For dinner, gastric bypass patients can try a 3 oz. portion of broiled soul with 1/4 cup of mashed potatoes. You can also try 3 oz. of lean stewed meat, such as chuck shoulder, with 1/4 cup of soft cooked green peas. For vegetarians, saute 1/2 cup of tofu with some low-sodium soy sauce and serve with 1/4 cup of brown rice.
