Gastric Sleeve Diet Guide

PHASE 1: Pre-op Diet

Your gastric sleeve diet plan will change depending on your overall status. Food will be re-introduced into the stomach SLOWLY. This is done to avoid sudden expansion of the stomach and avoid any other complications. Normally, your doctor and nutritionist will provide you the diet plan. This includes what food to eat, not to eat, the time, fluid requirements, protein requirements and so on.

The 3 Stages of Gastric Sleeve Diet(Pre-operation)

By following the prescribed diet, your liver and body fat will lessen. Reducing the size of the liver means a safer, faster operation, and less bleeding during the surgery. Having smaller body fat will help your body prepare for the post-operation diet.

Here are important diet guidelines that you can take to prepare you for the big day:

  • Avoid sugary foods including pastries, cakes, high carbohydrate foods- pasta and bread, candies, and chocolates.
  • Avoid fatty and fried foods including red meats, butter, and margarine, deep-fried dishes
  • Avoid milk products- cheese, ice cream
  • Avoid carbonated beverages and alcoholic beverages

Nutrition Goals to help you prepare for surgery:

  • Eat three meals at regular times each day
  • Reduce non-hunger snacking
  • Eliminate sweetened beverages
  • Lose at least 10-15 pounds before surgery. Patients with a BMI over 55, should lose 10% of their body weight

NON-ADHERENCE TO THE ABOVE MAY RESULT IN CANCELLATION OF YOUR SURGERY.

 
PHASE 2: Post-op Diet

After surgery, it is important to follow the diet guidelines given by the doctors. Your stomach can only accommodate nearly four ounces of food. It is vital not to overload or under load it to avoid further complications. 

Sticking to your diet and exercise are essential for a successful weight loss. Make few changes in your lifestyle and eating habits to ensure that you follow the guidelines.

Possible complications may include: hair loss, vomiting, dehydration, nausea, constipation, diarrhea, excessive gas, lactose intolerance, protein, and calorie malnutrition, gallstones, and mineral and vitamin deficiency.

In the next four weeks, NO SOLID FOOD IS ALLOWED

 

4 Stages of the Gastric Sleeve Diet

 

 

Stage 1: FULL LIQUID WITH PROTEIN

Starts on the 1st Day of Your Gastric Sleeve Diet

Hours after the surgery, you are only allowed to drink water.

Carefully observe your reaction to water. Sip small amounts every hour and be aware of signs of fullness. A recording sheet will be provided by a nurse or doctor. You will need to outline what time you drank water and how many ounces.

If your Physician sees you can tolerate water, you can start drinking water, apple juice, decaf tea, decaf coffee, sugar-free Popsicle, orange juice, sugar-free jello, flat diet sodas, and clear fat-free broth.

You do this slowly. Drink water and other clear liquids until your new stomach can adapt to the new food it intakes. You’ll feel full faster so be aware of that.

Avoid caffeine, sugar, carbonated beverages and other flavored beverages.

And again, Take small sips and be aware of feelings of fullness.

THE ONLY FOOD ALLOWED ARE

 

Only food allowed for Week 1

Stage 2: SLOWLY INTRODUCE
BLENDERIZED 
AND PUREED FOOD

Starts on the 2nd Week of Your Gastric Sleeve Diet

After drinking clear liquids for seven days, you can now start eating food in liquid or blenderized form.

Foods are blenderized for easy digestion. Make sure that all food are thinned and fine in consistency. Stage 3 can last for nearly two weeks.

From liquids, you transition to pureed food. Remember to do this slowly. Introduce new food to your stomach every day. Observe your reaction and be alert for any sign of fullness. 

You will start with small amounts of these liquids and pureed foods because you will feel full quickly. At first, you will have to eat small amounts frequently.

GUIDELINES FOR EATING PUREED FOOD…. 

From 2-4 ounces at a time, aim to get six meals a day. Again, protein intake must be at least 60 to 80 grams daily

The aim is to eat four to six meals of four ounces each day. Eat slowly and it should take 30 minutes to eat four ounces (1/2 cup).

  2. Decrease your portion size

 


IMPORTANT THINGS TO REMEMBER ON
THE FIRST 2 WEEKS OF GASTRIC SLEEVE DIET

  1. Eat three meals a day to ensure you are well nourished
  2. Do not skip meals and eat “on the run” as this tends to result in food being eaten too quickly with inadequate chewing. Also, the types of foods that are easy to eat “on the run” tend to be higher in fat and calories
  3. Continue to take your liquid or crushed multivitamin and mineral tablets unless advised differently by your dietitian or doctor
  4. Keep a food diary. It will help know what food disagrees with you and find what causes discomfort if you feel it
  5. Pay attention to your body’s signals of fullness
  6. If you feel nauseous, stop eating immediately. One extra mouthful of food after signals of fullness could lead to pain, discomfort, and vomiting.
  7. Use ice cube trays. Each cube holds about two ounces. This will help portion sizes. Try preparing reduced-fat cream soups or pureed meats and vegetable and store them in trays
  8. Protein comes first. Limit them to two to four ounces per meal
  9. Aim for four to six meals per day
  10. Drink at least eight cups of fluids per day


 

Stage 3: INTRODUCING SOFT FOODS

Starts on the 3rd or 4th Week of Your Gastric Sleeve Diet

With the approval of your physician, the dietitian will introduce soft foods in your diet.

He or she will review guidelines on how to successfully introduce semi-solid consistency foods without nausea and vomiting. At this point, you will advance to soft and easily tolerated foods.

A soft diet is recommended to provide an allowance for the stomach to recover from the surgery. Also called the transition diet, the soft diet is given between liquid and regular diet. This phase can be given to the patient for 3 to 8 weeks, depending on how their new stomach tolerates food.

FOODS TO AVOID ARE….

In soft diet, gas-forming foods, coarse bread and cereals, seeds, some vegetables and fruits are not allowed.

Protein requirement ranges from 60 to 70 grams and 64 ounces of liquid. The patient may take up to three servings of soft vegetables and a small portion of fat.

Protein sources include: Egg whites, fish, lean chicken, lean turkey, tofu, non-fat cheese, non-fat cottage cheese

Vegetable sources include: Avocado, banana, potato, carrots, green beans, squash, tomato and cucumber

Allowed FoodFoods To Avoid

Cooked eggs, any type except fried

Canned fruits (in their own juices or water)

Crackers

Pretzels

Hard rolls

Bread (toasted)

Skim milk

INSTRUCTION ON EATING AND DRINKING AT STAGE 3

  • Eat three meals and two snacks per day
  • Each meal should not exceed the volume of six ounces
  • Eat and drink slowly. Take at least 30 minutes to eat a meal
  • Take small bites, chew very well.
  • Sip on liquids during meals only if needed, but don’t drink large amounts during meals. Limit to one ounce of fluid per meal
  • Continue to drink low-calorie liquids between meals – at least 8 cups per day
  • Continue to take a vitamin and mineral supplement every day and introduce a calcium and B12 supplement

Reminder: Keep in mind that you are “re-educating” your stomach. When you eat too fast, too much, or don’t chew enough, you will feel discomfort and vomit.

 

Stage 4: LOW FAT, LOW SUGAR, HIGH PROTEIN DIET

Starts on the 4th or 5th Week of Your Gastric Sleeve Diet

Begin at this stage upon the approval of your physician and dietitian.

This is a gradual process. Slowly, you will learn how to incorporate protein sources in your diet other than supplements.

Advancing to this stage may take 2-6 weeks. Slowly add regular foods to your diet. From eating 3 meals a day, your goal is to eat 5 small meals a day.

Drink all your liquids slowly and NEVER drink while eating. You can only do that 30-60 minutes before and after eating. Otherwise, you will feel full easily and not get the proper nutrition your body needs. Other complications from doing this are nausea, vomiting, and feeling of discomfort.

A WELL BALANCED MEAL PLAN IS VERY IMPORTANT…..

Eat your protein meals first since they satisfy hunger longer. When you can eat more protein, decrease the amount of protein supplements you consume. If you were unable to take your needed amount of daily protein, which is 70 grams per day, you can supplement it with the necessary amount of protein shake.
