Understanding the Bariatric Surgery Diet

The diet after weight loss surgery gradually progresses from liquids to purées to solid foods. Because the size of your stomach is effectively reduced to about the size of 1 cup or less, your meals are smaller. You have to eat more frequently throughout the day, and you need to make sure you chew your food slowly and thoroughly, so it doesn’t become stuck and so it’s properly digested. You need more time to eat than you used to, but you’ll notice you feel fuller with less food. You eat and absorb fewer nutrients than you did before surgery, so to prevent deficiencies, you need to commit to a regimen of vitamin supplements for the rest of your life.

After surgery, your pouch is swollen and your diet has to progress gradually from clear liquids to solid food to prevent discomfort and the premature stretching of your pouch. This is done in the four main stages described below. In Chapter 2 we cover each stage in greater detail, including specific foods, daily menus, and helpful tips.

Specific dietary guidelines vary for each procedure and each patient. What we discuss are some of the general dietary changes weight loss surgery patients can expect after weight loss surgery.
