Weight loss surgery makes protein shakes essential
Whether you're considering bariatric surgery or have already had it, getting your protein is going to be a very important part of your life. (Read more on the pre-weight loss surgery diet and post-weight loss surgery diet.)
However, it may be hard for you to get all the protein you need from "regular" foods for a variety of reasons.
That's where and why protein shakes/protein powders come in to the picture.
There are so many brands and types of protein powder and shakes out there I can't count them with all my fingers and toes! That's why you need to know and understand the differences so you can pick one that's best for you.
Not all products are created equally and knowing what to look for and what to avoid is the difference between enjoying your shake...and spending time in the bathroom trying to recover from it.
Let's get on the same page with our terminology. I use the terms protein powder and protein shake interchangeably. Although it is possible to buy unflavored protein powders that taste horrible, most are flavored, and can be mixed with water or milk and translate into a nice protein "shake."
The Kinds of Protein
The source of protein in your shake can be derived from a variety of foods. Read the list of ingredients on the food label to determine the source. It will be one of the following:
Note that there are 2 kinds of whey protein:
The most popular shakes are made from whey protein concentrate, whey protein isolate, soy protein or even some combination of whey and soy.
Which protein source is right for you?
I suggest trying whey first, then soy or egg, and then any of the other plant sources named above. You'll get the most protein for the least calories from whey, egg, and soy. I recommend your shakes fall in the 150-250 calorie range.
If you're lactose intolerant (or become lactose intolerant, which is likely to happen after gastric bypass) choose shakes/powders made from only whey protein isolate (label will usually say "lactose free"), or soy protein. Avoid whey protein concentrate.
Protein Shake/Protein Powders: How much protein do they provide?
This varies depending on the brand. First of all, read the serving size! A serving is typically "one scoop" but occasionally it will be "two scoops."
Then read the label for the number of grams of protein per serving. Choose a product with at least 15 grams of protein.
How much daily protein you need varies but generally is in the 60-80g/day range. (Be sure to follow the recommendations of your physician.) If you have two shakes per day with 15 grams protein each, you'll get half your daily requirement by drinking 2 shakes.
If you mix protein powder that has 15 grams of protein with 1 cup skim milk/lactaid milk your resulting shake will be even higher in protein: 23 grams. Then 2 shakes provide 46 grams per day.
The amount of added sugar varies brand to brand. A protein powder with lots of sugar will taste really yummy but can cause dumping syndrome after gastric bypass surgery.
Choose a brand with the least amount of sugar possible: Ideally less than 5g, but if you must...no more than 15 grams.
You can use unflavored (i.e., unsweetened) protein powder to make a shake and use fruit and/or artificial sweetener to make it taste better while keeping the calories down.
Be sure to follow your doctor's recommendations as opinions vary. I've worked with one physician who likes his patients to choose shakes with less than 5 grams of sugar.
Know that 4 grams of sugar = 1 teaspoon.
This also varies brand to brand. Too much fat can cause dumping syndrome in the same way too much sugar can, and it also supplies excess calories.
Read the label for the number of grams of total fat and choose a brand with 5 grams or less.
Beside protein, sugar, and fat, protein shakes and powders can have added sodium, food dyes, artificial sweeteners and added vitamins and minerals.
Sometimes it's all that added stuff that upsets your stomach. Yellow #5 in a banana flavored shake or Red #40 and/or Blue #1 in a "berry" shake could cause you distress (plus these chemicals are just not healthy for you and some even may pose a health risk!). Also, while added vitamins and minerals sound good, the forms in protein powder are often cheap and hard to digest and may therefore upset your stomach.
Be sure to read the entire ingredient list. If the list of ingredients is really long and it looks like it belongs in a chemistry class, it's probably not the healthiest choice and you may have trouble tolerating it.
Summary: The Best Protein Shakes/Protein Powders Have:
These are my favorite brands and the ones I regularly recommend to my clients. See my protein shakes recipes to get some yummy ideas of how to mix them.
Note: The links below lead to different sites depending on where each product is sold. Some of the links go to search results so you can choose the size and flavor that you prefer. Have fun!
Note: Nutritional values may vary a little bit between flavors.
These are some of my favorite ready-to-drink protein shakes and drinks made especially for weight loss surgery patients.
You Can Even Get Liquid Protein!
Liquid protein is best used after surgery, when the volume you can eat is still very small. 1 oz of this liquid protein provides 15g protein.
No matter how yummy a shake tastes in the beginning, anything can get tiresome if you eat it day after day. Make sure you have a good variety of shakes to alternate between so you never get bored and are able to drink your protein shakes when necessary.
