Bariatric Surgery Post-Op Diet Guide

Post-Operative Diet Stages:

Stage 1: Clear Liquid Diet 5 -7 days

A clear liquid diet allows for healing time and to make sure that your body can tolerate anything by mouth. This phase takes a minimum of 2 days after your operation. At first, take in liquids every ½ hour – about 2 ounces at a time. Then gradually increase your intake of fluids to 6 to 8 ounces every hour. Drink very slowly and refrain from gulping.

The Goal in Phase one is to stay hydrated- you want to consume a minimum of 48 oz. of fluids, optimal goal 64 oz.

  • The Clear diet begins post-operatively if there is no nausea or vomiting.
  • You MUST sip VERY SMALL amounts of fluid ALL DAY.
  • The goal for a day is a total of 64oz of clear liquid per day by sipping SMALL SIPS 4-8oz per hour.
  • Recommended Sugar-Free Clear Liquids:
    • Clear Broth/Bouillon: Chicken, beef, vegetable
    • Gatorade/Vitamin water
    • Light or diluted (50/50) juices (apple, grape, cranberry)
    • Clear Liquid protein (New Whey Liquid Protein- Walmart, GNC, Rite Aid)
    • Unsweetened caffeine free herbal tea.
    • Jell-o.
    • NO carbonated beverages.

CLEAR LIQUID DIET SAMPLE MENU

Important: You do not weigh your fluids, you measure by volume. You can have as many fluids as your body wants. The minimum goal is 48 oz. To prevent dehydration:

WAKE-UP:

  • 6 oz. warm herbal tea (no milk/cream) or broth (warm fluids help in relaxing the stomach muscles)

BREAKFAST

  • 8:00 am – 6 oz. JUICE – Apple or cranberry, white grape, Gatorade, vitamin water (50% water/50% juice)
  • Sugar-free Jell-o

MID-MORNING SNACK

  • 10:00am- 6 oz. warm tea (no milk/cream) or broth

LUNCH

  • 12:00 – 6 oz. Vitamin water or clear liquid protein shake
  • Sugar-free Jell-o

MID-AFTERNOON SNACK

  • 3:00 pm – 6 oz. herbal tea or broth

DINNER

  • 5:00 pm 6 oz. white grape juice (50% water/50% juice) or clear liquid protein drink
  • Sugar-free Jell-o or Sugar-free Popsicle

EVENING SNACK

  • 6 oz. herbal tea or broth

Stage 2: Thick Liquid Diet 6-14 days

Goal is to stay hydrated and consume between 60 – 90 grams of protein

This diet allows a broad range of liquids and protein supplements. This will give your new stomach pouch and digestive system time to heal properly and allow you time to adjust to your new stomach pouch. A good rule of thumb for what is allowed on this diet is anything that has the consistency of what can easily be strained through a straw. Remember, however; at this stage you should not be sipping anything though a straw!!!!

Start taking your multi-vitamins, calcium and iron daily as directed. If you need guidance in this area or require vitamins, please contact us to purchase our recommended vitamins designed for you particular bariatric needs.

  • Start high protein full liquid diet
  • Recommended
    • All foods from the previous stage.
    • Protein powders
    • Greek Yogurt (remember it needs to have more protein than sugar- Fage/Chobani plain Greek yogurt)
    • Almond or Coconut Milk
    • Natural Apple Sauce
    • Vegetable juice (V8)
    • Hot cereals like oatmeal/ cream of wheat/Kashi hot cereal
    • Sugar-Free Pudding
    • Soups (chose higher protein soups like bean soup, can take chunky soups and blend before eating)
  • Avoid all carbonated beverages (fills the stomach with gas), sugar (extra calories that fight against weight loss) and coffee (it is acidic and may have problems with acid reflux after surgery. It is also a diuretic, causing you to be dehydrated)
  • Drink a minimum of 48 oz. of fluids and a goal of 64 ounces of liquids per day to prevent dehydration. Sport drink bottles with measurements on the side will help ensure you are drinking enough fluid. Remember, you will not be able to gulp liquids so you will want to drink small amounts throughout the day.

THICK LIQUID DIET

SAMPLE MENU

BREAKFAST

  • 1 oz. packet high protein oatmeal made with almond milk
  • One scoop unflavored protein isolate added in

Stage 3: Soft Solids Food (15 – 21 days)

Goal: start weighing food – 4 – 6 ounces total per meal, getting 20 grams of protein per meal (3 oz. will always be protein)- Protein first!

Chew all your food well to applesauce consistency. If you don’t follow these precautions, you may experience vomiting, stomach irritation, and swelling. You could also have obstruction of the small gastric pouch. If solid foods cause nausea and vomiting, go back to the liquid diet you had earlier. Then you can slowly add soft foods and eventually transition to solid foods. Vomiting may increase the incidence of band slippage, stomach slippage or stretching of the small stomach pouch above the band. IF VOMITING AND NAUSEA PERSIST, CALL YOUR DOCTOR IMMEDIATELY.

Think of your new pouch as shaped like a funnel. You can pour any liquid into this funnel, and it will run through and out the bottom. The same thing happens with your pouch when you only consume liquids. So you do not want to drink your calories or overeat.

As a part of your new life, you will want to STOP drinking 30 minutes before a meal and 30 minutes after a meal.

  • You begin to weigh your food at this stage- Goal is 6 oz. of food- 3 oz. of protein always and 3 oz. of other food (healthy fat, fruits, veggies, etc…)
  • Your goal is to work towards getting 20 grams of protein at each meal
  • Add only ONE food at a time.
  • Goal for day is 48-64oz of fluid to prevent dehydration
  • Cottage cheese (4%-whole fat)
  • Ricotta cheese
  • Soft Tofu
  • Scrambled Eggs
  • Texturized Vegetable Protein (TVP)
  • Egg, chicken, shrimp, tuna salad, (canned chicken, tuna, salmon)
  • Refried beans
  • String cheese or soft cheese like laughing cow

***THIS NEEDS TO BECOME A LIFELONG HABIT. ***

  • VERY IMPORTANT: STOP drinking 30 minutes before eating and DO NOT drink until 30 minutes after a meal.
  • Chew thoroughly and slowly.
  • Eat three meals a day and one to two protein drinks
  • Protein intake needs to be approximately 60 – 90g a day./li>

Stage 4: Solid Food (Day 21 and beyond)

Goal: 6 oz. of food per meal by weight, 3 oz. of protein (20 grams) & incorporating variety

Important Reminders: Remember to eat slowly. Cut your food into dime sized bites. Chew each bite thoroughly, at least 25 times, before swallowing. Do not drink any liquids ½ hour before you eat and during your solid meal. Do not drink any liquids for a ½ hour after your meal. Liquids will pass through your new stomach pouch quickly and will not make you feel full. Consuming only solids at each meal will give you the proper feeling of fullness (satiety) while limiting the amount you eat. Take at least 20 minutes to eat your meal. Always read labels.

  • All foods from previous stages.
  • Cheese (any cheese other than American or Velveeta)
  • Dried Beans: kidney, lentil, split pea.
  • Lean Meats: fish, tuna, chicken, turkey. Make sure all meats are moist.
  • Canned fruit in natural juices
  • Soft cooked vegetable
  • Be careful of fibrous/gassy vegetables (celery, broccoli, cabbage, etc…)
  • Avoid the membrane of the fruit (skin on citrus)
  • Avoid tough meat.

Remember:

  • Only add ONE new food at a time!
  • Avoid starchy food like white rice, pasta, bread.
  • Chew thoroughly and slowly.
  • Protein Supplements: 60-90g.
  • In between meals, drink at least 6-8 cups of water and any other non-calorie or sugar-free, non-carbonated beverages.
  • Stop drinking 30 minutes before eating and DO NOT drink until 30 minutes after a meal.
  • EAT 6 small liquid and blended meals each day, but add one solid food item at one meal the first day. Add one more stable food item each day.
  • ALL NEW FOODS NEED TO BE SOFT, COOKED OR CANNED.
  • AVOID all raw fruit and vegetables, nuts, popcorn, pickles, olives or relishes.
  • RECORD all new foods and any problems you have with them in a food diary and let your doctor know of any problems or questions you may have.
  • CHEW your food very well before swallowing. The consistency of the food should be liked mashed potatoes. Make sure that each bite is tiny (as if you were feeding a baby) and continue to eat small amounts slowly. Eat about 2 Tablespoons for 10-15 minutes.
  • CONTINUE to take your multiple vitamins, calcium supplements, iron and B12 supplement as directed.
