The first few weeks after Gastric Sleeve surgery are a liquid diet, and there are a number of liquid protein supplements out there. In fact, after you begin on solid food, you will probably go back to liquid protein for a few months to supplement your intake.

 Foods that go down easy the first month after the gastric sleeve:

Fish has a texture that goes easily through the stomach the first month after you begin a solid food diet. There are many different fish recipes that work well with Gastric Sleeve surgery, and you can find a number of them on

For people who say “I don’t like fish,” my response is – this is a new lifestyle and part of surgery is trying new things. Most people who have had bad experiences with fish is because the fish is too “fishy” tasting. The key is to buy great fish – but since you won’t be eating much, you can purchase small amounts.


Tips for fish buying:

  • Ask to smell the fish. If it smells like the ocean – buy it. If it smells fishy, don’t buy it. Do not depend on someone else’s sniffer for this- it has to be yours.
  • The fish – if it is whole, should have clear and not cloudy eyes.
  • Ask the fish monger (the person who sells fish) when the fish came in.

Other fish that people like that work well with the gastric sleeve – tuna fish. A wide variety of canned tuna is available from very inexpensive to quite expensive. Find one that you like. My favorite is the hardwood smoked tuna from

Canned salmon is a great way to get wild salmon that was caught on a ship and canned the day it was caught. It can be used, like tuna, in a variety of ways.

Egg salad is a great protein to use after Gastric Sleeve surgery – you can mush the eggs with your favorite ingredients and make a great dish – here is my favorite recipe:

  • Four eggs
  • 1 Hass avocado – ripe
  • 1 ½ tablespoons of chopped onion
  • 1 tablespoon of fresh parsley
  • 4 tablespoons of sweet pickle relish
  • 1 tablespoon of Greek yogurt
  • 2 teaspoons of Dijon mustard

Boil the eggs and cool. Mash the eggs in a bowl. Add the avocado, onion, and parsley. Then add the remaining ingredients. Add salt and pepper to taste.

The first month after Gastric Sleeve surgery is the time for new recipes…

…that you have never tried before.  But because the stomach is still small, you want to have those textures of foods that go down easily.

The first month after Gastric Sleeve eat fish and eggs as a primary protein source. You could also use soy products like Tofu or Tempeh, or even some beans.

The idea is simply softer proteins – and not overcooked proteins.

I can’t eat anything I like after having Gastric Sleeve surgery!!!

Well, probably the burger won’t go down easily the first month after surgery.

Some feel that they are deprived after having the Gastric Sleeve – unable to eat much and noting how much food is a part of social situations.

The key is to focus your efforts from trying to eat foods that got you to be a Gastric Sleeve patient to those foods that are new and with new flavors. This is the time to change quantity of food with quality of food and with flavors of food. Think spices. Think herbs. Think great flavors.

This is why you find some basic fish protein that you like and start to dress it up a bit with flavors:

Halibut goes great with some citrus – like lemon. But also a bit of Parmesan cheese and some macadamia nuts.

Think of the egg salad up there and instead of sweet relish consider using some radish or some pickled radish or even a great dill pickle to perk up the senses.

So, yes, you will eat small, but you will eat to live instead of live to eat. But this means – flavor – flavor – flavor.

The texture of proteins and Gastric Sleeve surgery

The other issue with proteins is most are overcooked. When they are over-cooked, they are hard to get down. Before surgery, you may have choked them down with sauce. Now it is time to learn to make them better.

Two tips for successful eating with Gastric Sleeve surgery:

  1. Get a Sous Vide machine – about $300 bucks on up.
  2. Get an instant read thermometer and take the chicken out of the oven when it reaches 150 degrees. If you wait ’til 160 degrees (most recipes), it will be overcooked and dry. So, don’t do that.

So – start to experiment with flavor and good foods.

Good proteins are a key to eating healthy with the Gastric Sleeve.

Flavor is a key to enjoying new foods after Gastric Sleeve surgery and re-purposing the older foods.
