The minimum protein requirement for women is about 50 to 60 grams per day and men need 60 to 70 grams of protein per day. It's usually not possible to consume that much protein from foods alone during the first month after bariatric surgery. Most bariatric surgery patients use liquid protein supplements of some kind during the first few months after surgery, and many continue to use them as a convenient source of protein for the rest of their lives.

Some of the more popular liquid protein supplements used after bariatric surgery include portion-controlled shakes & drinks , hot drinks, soups, puddings, and liquid protein supplements.

Avoid using a straw and continue to sip slowly throughout the day, 1 to 2 ounces over 30 minutes.

They include the broth of low fat, cream bariatric soups, protein shakes & smoothies , skim milk, yogurt and diet puddings, and liquid protein supplements

Soft foods should be tender and easy to chew, such as ground or finely diced meats, canned or soft fruit, cooked vegetables, rice, macaroni, noodles. During this diet transition, you will eat many small meals a day and sip water in between. Perhaps starting with six small meals a day, you will then gradually progress to four meals. Meals should include protein rich foods, such as lean meat, yogurt and eggs. You will usually eat soft foods for about eight weeks before progressing to regular texture foods, as recommended by your surgeon of dietitian.

Meals will focus on lean sources of protein, fruits, vegetables and whole grains. Your surgeon or dietician will usually prescribe a reduced calorie diet (1000-1200 calories per day) to continue your weight loss. Continue to limit your intake of high-sugar, high fat foods that are loaded with calories, but devoid of nutrients. You'll also need continue to take vitamin and mineral supplements for life, to compensate for the nutrients that you're no longer able to absorb through the bypassed parts of your stomach and intestine.

Long Term Bariatric Surgery Diet Tips:

  • Eat Proteins first. Protein is the most important nutrient in the bariatric diet. Foods high in protein should always be eaten first, just in case you feel full and cannot finish the meal. Each meal you eat should include protein. Most bariatric health care providers recommend an intake of between 60 and 100 grams of protein each day.

  • Eat small meals. Though your stomach will gradually stretch as time goes on, you won't be able to eat more that 1 to 1 1/2 cups of food at a time. Eat three to six small meals a day, with each meal no more than six to eight ounces in size. Incorporate two or three healthy protein snacks if hungry. Make sure to eat only the amounts recommended by your surgeon or dietitian, and stop eating before you begin to feel full.

  • Eat and drink slowly. Take at least 20 to 30 minutes to eat your small meals and 30 to 60 minutes to drink 1 cup of fluid. Use of Take time to chew foods thoroughly - aim for 15 to 20 chews per bite. Your small stomach pouch and narrowed outlet require a slow, well chewed passage of food to ensure nothing gets stuck, and to avoid problems such as dumping or vomiting.

  • Avoid drinking fluids with meals. Drinking fluids with meals may may force foods through your small stomach pouch too quickly, causing you to become hungry again quickly. It can also cause abdominal pain, nausea, vomiting and a situation called dumping syndrome in gastric bypass patients.

  • Include fruits and vegetables with meals.

  • Keep hydrated. Aim to drink 6 to 8 cups of water each day. Choose beverages that are non-carbonated, as the gas produced can stretch the stomach pouch or the opening to the intestine. Artificial sweeteners added to water such as Crystal Lite® are acceptable, as well as flavored waters, decaf coffee or tea, broth and diluted fruit juices.

  • Take your vitamin and mineral supplements every day. To prevent vitamin and/or mineral deficiency, you will need to take vitamin and mineral supplements every day, for the rest of you life, as prescribed by your surgeon or dietitian. Required daily supplements may include a mulitvitamin/mineral, calcium, vitamin B-12 and possibly an iron supplement.
