The Ultimate Guide to
Bariatric Protein Shakes 

Bariatric Protein Shakes are A MUST 

Drinking bariatric protein shakes is the ONLY way to hit your protein goal in the beginning months after weight loss surgery.

How else are you going to get down the 60-80 grams of protein daily that your surgeon has asked you to have? Note: Be sure to follow YOUR surgeon’s exact bariatric diet guidelines.

 One 3oz chicken breast has approximately 20 grams of protein…

 …so you’d have to eat 3-4 chicken breasts per day to hit your protein goal!

 With a new stomach the size of an egg or small banana (depending on which surgery you had), the ONLY way to hit those big protein numbers in the beginning is to drink your protein!

 Enter the “bariatric protein shake.”

Ready Made or Home-made Bariatric Protein Shakes?

There is no right or wrong here.

 One is not better than the other. It’s simply a matter of time or money.

Popular Ready Made Protein Shakes

The ready made/ready to drink (RTD) protein shakes are convenient, so they will cost you more $$….just like buying cut up pineapple costs more than a whole pineapple!

 If you start from scratch and mix up your own concoction with your blender (or a shaker cup), you’ll save money, but it will cost you your time.

 Hey, you could always use a combination of the two!

 …Use ready made protein shakes on your work day or when you’re in a hurry or on the go…

 …and when you have a little more time on your days off or on weekends, mix them up yourself.

Exactly How Much Protein Do Bariatric Protein Shakes Need to Have?

Well it depends.

How far out of surgery are you?

In the beginning, you get ALL of your protein from protein shakes because you can’t eat enough real food.

Over time as you’re able to eat more protein from Greek yogurt, cottage cheese, eggs, beans, fish, and chicken, you don’t rely on the protein shakes as much.

If you pick a protein shake that has only 10 grams of protein in it, then you need to drink 6-8 of them to hit your protein goal, right? Not happening!

Think about it…if each shake is 11oz, then 6-8 of them would be 66-88oz. There is no waaaay you’re going to be able to get that much volume down.

So in the beginning…

 …pick a protein shake with 30-40 grams of protein each. Then you only need to drink 2 per day to hit a protein goal of 60-80g/d.  Brilliant! And totally do-able in the beginning.

As time goes on and you can eat more protein rich foods, its ok to drink protein shakes that have slightly lower protein counts.

Use of Bariatric Protein Shakes
Can Be Summarized Like This:

  • In the first weeks get ALL of your protein from protein shakes.
  • For the first few month, get MOST of you protein from protein shakes and supplement with food.
  • In the long term…get most of your protein from food and supplement with protein shakes only if necessary.

It’s important to note that everyone heals at a different pace and there is no exact bariatric protein shake schedule to follow!

Use protein shakes as long as you need to use them, to help you meet the daily 60-80 grams protein goal.

What Happens If You Don't Get Enough Protein?

  • Slow healing
  • Low energy
  • Muscle loss
  • Hair Loss!!!! (This is what everyone is always most worried about!)

Did I mention hair loss? ;)
