Gastric Bypass and
Gastric Sleeve Diet
Immediately after your gastric bypass or gastric sleeve surgery, you won't be
able to eat for one to two days. After a couple of days, you will be able to eat
some very specific foods according to a diet progression. The purpose of the
gastric bypass diet progression is to help you in the healing process, minimize
stress on surgical areas and allow time for your body to adjust to new eating
patterns.
Common phases in the gastric bypass and gastric sleeve diet:
Phase I - Liquids - foods and fluids that are liquid or semi-liquid at room
temperature and contain mostly water, such as broth, juice, milk, strained cream
soup and cooked cereal. In most cases, you stay on a liquid diet for one to two
days.
Phase II - Pureed foods - foods with a consistency of a smooth paste or a thick
liquid. Pureed foods contain no distinct pieces. The pureed diet is generally
followed for three to four weeks, or as recommended by your dietitian or doctor.
Phase III - Soft foods - foods that are tender and easy to chew, such as ground
or finely diced meats, canned or soft, fresh fruit, and cooked vegetables. You
usually eat soft foods for eight weeks before progressing to eating foods of
regular consistency with firmer texture as recommended by your dietitian or
doctor.
During the diet progression, you eat many small meals each day and sip liquids
slowly throughout the day (but not at the same time you eat). You may start with
six small meals a day, then progress to four meals and then finally, when
following a regular diet, decrease to three meals a day. Typically, each meal
will include protein-rich foods, such as lean meat, low-fat dairy products
(yogurt, cheese) or eggs. Protein is important for maintaining and repairing
your body after surgery.
How quickly you move from one step to the next depends on how fast your body
adjusts to the change in eating patterns and the texture and consistency of
food. People usually start eating regular foods with a firmer texture three
months after surgery, but it can occur sooner.

You may drink anything that is clear and liquid at room temperature. Avoid
caffeine and carbonated drinks.

adjusting the temperature. Please follow your doctors' recommendations on how
long to follow each diet.
