Eating Healthy After Gastric Sleeve Surgery – Make It Your Lifestyle!

Healthy After Gastric Sleeve Surgery
Written by Nancy

You’re out with friends enjoying dinner at a trendy restaurant; it’s time to place your orders.  One of your friends will have the filet mignon with mashed potatoes and gravy; the second orders spicy penne pasta with shrimp. You are still undecided, not due to scarcity of options but because there are too many!

The fact that you cannot order what you really want (fish and chips with tartar sauce) is disheartening. You’ve just had a Gastric Sleeve Surgery, and you know your options are limited.

But you need to focus on the bigger picture; the success of your surgery is directly related to what you eat.

During First Week after Surgery – Clear Liquid Diet Only

You will be served a bariatric approved clear liquid diet during this phase. There are some guidelines that you must follow to make this time easier, such as:


  • Sip fluids slowly
  • Don’t use a straw or bottle
  • Don’t gulp the fluids

Foods that can be safely consumed during period are: ice chips, water, sugar-free Jell-o, clear broths (made from chicken, beef, and vegetable), crystal light or other sugar free drink mixes, sugar-free popsicles, unsweetened and caffeine free tea.

After First Week of Surgery – Graduate to Full Liquid Diet

You will slowly transition to an all full liquid diet after a week. Consume as much as protein as possible during this time period, in liquid form. Required amount of protein is 60–70 grams, in 60 ounces of liquids daily.

Some approved liquids are: Skim milk, soy milk (especially if you are lactose intolerant), sugar free gelatin, soups, fully blended fruit smoothies, sugar free popsicles, applesauce, and protein shakes.

Start a Soft Foods Diet – For a Week

After a week of all liquid diet, the body becomes ready for soft foods. This transition is typically recommended by surgeons after a week or more of liquid diet and should resume for a week. Patients are suggested to continue consuming 60 to 70 grams of protein every day. They must also avoid sugar, fat and carbohydrates.

Approved list of soft foods include: mashed fruit, mashed vegetables, scrambled eggs, tuna fish with low-fat mayonnaise, low fat cottage cheese, bananas, mashed potatoes, and yogurt.

Additional Considerations

Your stomach is still acclimating to the new stomach size, meaning several smalls should be consumed in a day. Serving size shouldn’t be more than 3 to 4 ounces at a time. Calorie intake on the other hand should be 600 to 800 in a day.

Four Weeks after Surgery – Solid Foods Diet

After 4 weeks of preparation, you will now be ready to eat solid foods. All the foods that you will eat for the rest of your life are included in this transition. Even though bariatric surgery is an effective solution for healthy weight-loss, the end result is still dependent on the food choices you make.

Strictly following the above guidelines will make sure you lose weight in the safest way possible. Remember, deciding to go through bariatric surgery should be accompanied by a well-thought and executed diet plan.
