Best Protein Powders for Gastric Sleeve Patients

Getting the right amount of protein is especially important for gastric sleeve patients. After testing five different products, I’ve determined that Dymatize ISO 100 Whey Protein Powder is the best protein powder for gastric sleeve patients. 

Protein is always an essential component of your diet, but after gastric sleeve surgery, it is more than critical for your recovery. The suitable protein powder can make the recovery process even more successful, but picking the wrong powder could potentially derail your body’s healing. 

The high-quality ingredients and excellent nutritional value are only some of the reasons why Dymatize ISO Whey Protein Powder has made the top of the list. 

Of course, every post-op patient may have different needs. You may need a different protein powder if you’re following a vegan diet, are gluten-free, or prefer to consume your powder in smoothies or baked goods. 

Keep reading for an in-depth look at the best protein powder for gastric sleeve patients. 



Importance of Protein After Surgery 

Protein can be helpful for anyone, but with the rapid weight loss that comes after gastric sleeve surgery, any post-op patient must consume enough protein to keep a healthy metabolism and limit muscle mass loss.

If you aren’t able to get enough protein while you lose weight after a gastric sleeve surgery, your body may begin to lose the existing muscle mass that you have. Since your body won’t have enough protein to rebuild what it has lost, gastric sleeve patients without adequate protein may also begin to experience adverse side effects due to a lack of nutrition.

Maintaining or rebuilding muscle not only helps prevent unsavory side effects like hair loss, but it can even reduce the amount of loose or sagging skin left after your rapid weight loss too. 


Best Source of Protein After Surgery

After surgery, while the body is healing, protein is vital. Protein will help your body rebuild itself and normalize after surgery. 

As your appetite regulates due to a smaller stomach, it can be complicated to meet all of your protein needs through meat and dairy products. Instead, you can try reincorporating more protein into your diet through a protein powder.

While it’s important to talk to your doctor about your personal nutrition plan, gastric sleeve patients typically require between 65 to 75 grams of protein daily. Without this crucial nutrient, it is easy for your body to lose lean muscle. 

You can expect to be able to start taking in liquids, including drinking protein shakes, by day two after surgery. While all patients need to consult their doctors for a meal plan, this is typical. 

Choosing the right protein shake is essential because some of them are meant for weight gain. The best protein for gastric sleeve patients will be low in calories and high in protein/nutrition.

What Should I Be Eating Pre-Op?

Getting ready for surgery is essential. Your lifestyle is about to change when it comes to your relationship to food, so developing healthy habits beforehand can help you have a speedier and more successful recovery and result. 

Getting lots of protein before surgery is essential. You can start incorporating high-quality protein powders and shakes in the weeks leading up to surgery. You’ll also want to include lean meats and whole grains. These foods are low in fat yet high in satiation and nutrition. 

The most important thing you can do is listen to your doctor’s advice and any recommendations they may have for your pre-op diet. 


What Should I Be Eating Post-Op?

Immediately after the surgery and for the first day, you will not be eating anything. Don’t worry about feeling hungry. The surgery is likely to reduce your hunger hormone, ghrelin

Around day two, you will be able to start taking in liquids, including:

  • Water 
  • Clear broth 
  • Unsweetened fruit juices
  • High-quality protein drinks 

After that, your recovery comes in phases, gradually incorporating soft foods, then ground meats until you can eat regularly. 

After the healing is complete, it is vital to maintain a healthy, high protein, low-calorie diet. Choose foods that give you plenty of nutritional value in relation to the calories.
