Bariatric Surgery Program
After Surgery
Dietary Adjustments
Bariatric surgery modifies your gastrointestinal tract and requires permanent
changes in your eating habits that must be adhered to for successful weight
loss. Your surgeon will provide to you post-surgery dietary guidelines.
It is most important that you adhere strictly to your surgeon’s recommended
guidelines.
General Dietary Guidelines
The following are some of the generally accepted dietary guidelines
a weight-loss surgery patient may encounter:
- When you start eating
solid food it is essential that you chew thoroughly.
- Chew your
food at least 20 to 30 times before swallowing. You will not be
able to eat steaks or other chunks of meat if they are not chewed
thoroughly.
- Don’t drink fluids while eating. They
will make you feel full before you have consumed enough food.
- Omit
desserts and other items with sugar listed as one of the first
three ingredients.
- Omit carbonated drinks, high-calorie nutritional
supplements, milk shakes, high-fat foods and foods with high fiber
content.
- Avoid alcohol.
- Limit snacking between meals.
- Do not chew gum.
- Do not drink through a straw.
Support from a Dietician or Nutritionist
Compliance with post-operative dietary guidelines is very important.
For this reason, you may be referred to a dietitian, nutritionist and/or
a bariatric surgery psychologist.
The nutritionist can help you learn how and what foods and fluids to eat
and drink following the surgery. A bariatric surgery psychologist can help
educate and prepare both you and your family for the changes that accompany
weight loss, and assist you in following the post-operative guidelines.
Protein Sources
After surgery you will be eating very small amounts of food. In order
to prevent malnutrition, your body needs an adequate amount of protein
to remain strong and healthy. Protein is the building block that the
body uses to build new tissue, preserve muscle tissue and repair wounds.
It also helps the immune system fight infections.
Good protein choices are lean meats like skinless chicken, trimmed round
steak, lean pork chops and fish. Low-fat or fat-free cheeses, cottage cheese,
skim milk, fat-free plain yogurt, whole eggs or egg whites, and beans are
also good protein food choices.
The Holy Cross Hospital Outpatient Nutrition Counseling Center prepared
the following information to help bariatric patients consume adequate amounts
of protein after surgery.
Protein Counting Food List
Use this chart to select high protein foods and
calculate how many grams of protein you are eating a day. Aim for 60 grams
of protein a day and gradually increase to 80 to 100 grams a day.

between meals.
It is important to use your protein supplement
drinks to get enough protein in a day. Meat is not always tolerated
right away. Keep track of this and reintroduce at another time.
