What to eat and avoid on the gastric sleeve diet

A gastric sleeve procedure surgically reduces the stomach to about 15 percent of its previous size. The operation helps people who have it to feel fuller faster and greatly reduces overeating.

After surgery, a person must follow a strict diet that enables the body to recover and adjust to a smaller stomach size.

Surgery recipients will need to eat smaller and more frequent meals for the rest of their lives. Here is what someone can expect from the gastric sleeve diet.

  • Gastric sleeve surgery is so-called because the stomach resembles a sleeve afterward.
  • The reduced stomach size makes it difficult for someone to overeat.
  • The surgery's success depends on a person's willingness to stick to a healthy lifestyle.
  • The gastric sleeve diet follows four distinct phases for getting back to a healthful eating pattern.

What are the basics?

In gastric sleeve surgery, a surgeon reduces the stomach to a sleeve-like shape by removing much of the stomach.

The surgery is irreversible and can help people lose 60 percent or more of their excess body weight.

It also reduces the body's ability to produce a hunger hormone called ghrelin.

This lets most people feel hungry less often after their surgery.

The gastric sleeve diet is a multiphase diet designed to prepare people for surgery, help them recover, and transition to a lifetime of healthful eating.

People who cannot have gastric sleeve surgery or want to try lifestyle remedies before considering it may be interested in trying the gastric sleeve diet.

However, research from 2011 and published in the journal Obesity Surgery, suggests that gastric sleeve surgery causes nutritional deficits.

So, rather than trying the gastric sleeve diet, someone might want to consider reducing their portion sizes and sticking only to healthy foods first.

Phases of the gastric sleeve diet

The four phases progress so that people can transition to a solid food diet that they will eat for the rest of their lives. Some doctors also require a special pre-operation diet to optimize health ahead of the surgery.

Every individual should discuss details of a healthful pre-operation diet with their doctor since the right diet varies from person to person.

Phase 1

Phase 1 of the gastric sleeve diet usually lasts for about a week after surgery. During this time, people should consume only clear liquids.

Remaining well hydrated following surgery can speed the healing process and help with symptoms, such as nausea and vomiting.

While it can be hard to stick to a clear liquid diet, most people feel little or no hunger in the days immediately following their surgery. They should also avoid consuming:

Instead, people should drink sugar-free clear liquids. In addition to at least 8 glasses of water per day, a clear liquid diet can include:

  • jello
  • broth
  • decaf tea or coffee
  • sugar-free popsicles
