Bariatric Advantage Meal Replacement powder

One of the biggest struggles with the duodenal switch weight loss surgery is getting enough protein. My entire approach toward food has changed; where once I could eat and eat and eat, and wanted to, now I can’t, and even when I can eat, I often feel ambivalent or even turned off by food. But it’s imperative that I keep my protein intake up; that plus weight training are the one-two punch that will ensure I lose fat and not muscle.

To make sure I get enough protein, I’ve been tracking what I eat with SparkPeople. In the beginning I aimed for 60 grams of protein per day, but now that I’ve added more exercise and my stomach seems capable of handling more food, I’ve upped my goal to 90. I generally end up somewhere in the 80s.

While I think the ideal situation would be to get all my protein from real food, I’m not sure that’s actually possible. I’ve tried. Even on days when I forced myself to eat virtually nonstop (which is not recommended), I wasn’t able to get much further than the 50s. So to assist me in this endeavor, I’ve turned to various protein supplements.

When I originally looked at all my options, I thought it would be easiest to depend on products I could buy locally. I started out with New Whey Liquid Protein, which I’d tried out shortly after surgery and which was available at the smoothie place up the street from our apartment. Each little tube contains a whopping 42 grams of protein. I’d heard that the non-citrus flavors weren’t very good, so I stuck with orange.

However, New Whey isn’t something you’d want to drink regularly. For one thing, it replaces too much food. For another, it’s not delicious. Also, some weight loss surgery patients have trouble with whey protein (though I didn’t seem to). Regardless, one day I drank a tube of Liquid Protein and decided, “Never again. Or at least not for a very long time.” Now I think New Whey is probably good to keep on hand for emergencies, but not to depend on routinely.

After that I switched to Atkins Advantage shakes. They come in four flavors: Dark Chocolate Royale, Chocolate, Strawberry, and Vanilla. I tried them all, but they were all too chalky save the Dark Chocolate Royale, so that’s what I’ve stuck with ever since. I keep one compartment on the door of my fridge loaded up with Atkins shakes and have them for breakfast or snacks. Unlike New Whey, these don’t pack a lot of protein: just 15 grams. But that’s enough to get me going in the morning and help me transition to regular food for the rest of the day.

I’ve also been using Atkins Advantage meal bars as snacks. Their protein content differs depending on the flavor. I like the Chocolate Peanut Butter Bar (19 grams), the Mudslide Bar (15 grams), and the Cookies n’ Creme Bar (15 grams). I try not to have an Atkins shake and an Atkins bar in the same day, because again I’m leery of replacing too much food. Also, the bars tend to have a lot of carbohydrates, which I’m trying to avoid–the best carbs come from vegetables, brown rice, and whole wheat bread, if I must have carbs at all. The shakes don’t really have this carbohydrate problem, so I tend to depend on them more than the bars, but sometimes I want some kind of treat for a snack, and the bars are the closest thing I can do.

At this point I’d like to point out that it’s important to avoid sugar during this period of rapid weight loss. I’m also avoiding most artificial sugars, because they can cause unpleasant gastric side effects. However, sucralose (Splenda) seems to be okay, so I do use that. The Atkins products are all made with sucralose.

This system has been mostly working for me. I’ve been trying to incorporate more protein-rich foods and snacks into my diet, too. But getting to 90 grams of protein per day is still a challenge. So finally I thought I’d look for a shake that packs more of a protein punch.

I ordered one Ready to Shake Meal Replacement from Bariatric Advantage to try it out. They sent a plastic bottle with a screw top; inside the bottle was a pre-measured amount of powder to make a shake with 27 grams of protein.

protein shakeThe idea is that you put water or milk into the bottle, shake it, and drink, but it proved a little more challenging than it sounds. When I put the water in, the powder at the very bottom became a paste, not unlike what happens to powdered hot cocoa. I had to use a straw to scrape the powder off the bottom. Then the sludge was caught in the straw, so I had to blow it back out and try to mix it all up again. Finally it was done, and I threw the straw away…but then when I started to drink, replacing and removing the cap as I did so, I realized that the shaking had coated the inside of the cap with liquid, meaning I would spill it each time I took the lid off. Plus, drinking from the ridged mouth of the bottle was unpleasant. Fortunately I had another straw, so I popped it in and finished the shake that way.

The taste isn’t unpleasant. Right now I’d say I like Atkins better, but I’m not sure if that’s just because I drink the Atkins shakes refrigerated or not. Neither Atkins nor this shake is delicious.

The shake might taste better with milk instead of water, too. I didn’t realize I could use milk until I went to Bariatric Advantage’s recipes page. There I also found a lot of other information:

  • You can make shakes and smoothies with the powders using a blender.
  • You can make ice cream with the powders.
  • You can stir the powders into other foods, like oatmeal or soup.

I think at this point it would behoove me to get some of the unflavored powder and try it out in various recipes. This sounds like a great way to keep getting real food into my system while bumping up the protein.

I’m not sure I want to commit to the shakes at this point, though. I like the idea of making shakes and smoothies with ice and a blender, but I don’t actually have a blender, and I’m not won over by the taste of the shake. What I may do is buy a large bag of unflavored powder for cooking and then get one or two small packets of flavored powder to try out as shakes or ice cream. I’ll probably stay away from fruit smoothies, since even natural sugars can retard the rapid weight loss.

[EDIT: A few hours after finishing the shake, I had piercing lower abdominal pain followed by diarrhea. I will not be purchasing any more Bariatric Advantage protein powder.]

This surgery has given me a whole lot of new things to keep track of, but it has so been worth it. As of today, I’m down 76 pounds! Now I’m 43 pounds away from my “I could be happy at that weight” goal and 57 pounds away from the weight all the online calculators tell me I should be. It’s amazing that either way, I’m closer to the goal than I am to where I started!


  1. Thank you for posting this. I am scheduled for RNY on Feb 15, and I know I will have to use the protein shakes. I have no idea where to start with these various shakes/mixes because I’ve heard some of them taste awful. It was good to hear feedback on a few options. I think I will try the Atkins shakes and maybe get a few samples from my doctors office. I don’t want to spend alot on something I won’t use. Good luck on your weight loss. Thanks again for the post!

  2. Thanks for reading, Jennifer!

    I am about to update this post with a gross side effect I had from the Bariatric Advantage shake. Needless to say, I don’t think I will be using their powder at all. However, I can recommend Atkins Advantage Dark Chocolate Royale shakes. They’re kind of like Slim-Fast, and since they’re pre-made, you don’t have to mess with powder. And those New Whey drinks are great in the beginning when you can’t eat much at all, so I would definitely keep those on hand if I were you.

    Good luck!

  3. I will trust your doctors advice but that amount of protein sounds like a LOT of protein. Will you be able to reduce to a more normal level after you get to a stable weight? I just looked it up and the FDA said something like 47 grams a day for a healthy female.

  4. The particular surgery I had makes two big changes to the gastrointestinal system. First, it reduces the size of the stomach to a sleeve, so that I’m physically unable to eat more. Some patients stop at this point, which is known as the “gastric sleeve”. However, my surgery, the duodenal switch, also reroutes the intestines such that food no longer passes by much of the parts of the intestine that absorb food. This is known as “malabsorption”. It means that I no longer process a lot of the food I take in. That’s why I basically have to shoot for double the amount of protein. It’s also why I have to take a lot of supplements to make sure I have enough vitamins and minerals.

    The malabsorption is really beneficial in terms of fats; mostly fats just pass right through me. Unfortunately sugars and carbs can still affect me, so I have to watch out for those, especially during the “rapid weight loss” period. But with the smaller stomach and the intestinal changes, I no longer crave food like I used to, so it’s much easier than it was in the past.

    So no, I won’t be able to go back to a “normal” level of protein after I lose weight, but I will be eating what’s normal for me :) It should become easier as time goes on and my stomach expands.
