5 Reasons Nick’s Keto Protein Bars Belong in the Trash (Not Your Stomach)

Nick's Keto Protein Bars Comparison Chart

Sweden gave us ABBA, IKEA… and now, “healthy” candy bars? Nick Luthman, the Swedish engineer behind Nick’s Keto Protein Bars, once faced a pre-diabetic diagnosis.

His solution? A low-carb lifestyle and a dream of guilt-free treats. Fast forward, and we have Nick’s Keto Protein Bars, marketed as the answer to our sweet cravings. But beneath the shiny wrapper and “no added sugar” claims, these bars raise some serious red flags.

1. The Candy Bar Charade

Nick’s Keto Protein Bars aren’t fooling anyone. They look like candy bars, they feel like candy bars, and, most importantly, they taste like candy bars. With flavors like Choklad Peanöt, Triple Choklad, and Karamell Choklad, they practically scream “guilty pleasure.”

And that’s by design. By mimicking the irresistible qualities of our favorite junk foods, Nick’s is playing a clever game of “healthy indulgence,” blurring the line between a nutritious snack and a sugary treat (as one poor customer on Amazon discovered):

Let’s be real: chocolate, nougat, caramel, and peanuts are not health food, no matter how much protein powder you throw in and sugar you take out. These ingredients are calorie-dense and nutrient-poor, offering little more than empty calories.

Indulging in these treats too often can mess up your metabolism, leading to weight gain, blood sugar spikes according to Heather Yoshimura (Adult/Gerontology Nurse Practitioner), and a host of other health problems. So, while Nick’s bars might satisfy your sweet tooth, they won’t do your body any favors. While they may offer a temporary dopamine hit, they lack the sustained energy and nourishment that our bodies truly need.

2. The Sugar Sham

Sadly, “No added sugar” doesn’t mean something is healthy. While it may be technically true that no sugar was added, these bars are loaded with erythritol, xylitol, and stevia – sugar substitutes with their own baggage. According to Yale New Haven Hospital, sugar alcohols like erythritol and xylitol can wreak havoc on your gut, causing bloating, gas, and even diarrhea.

While they’re not fully absorbed like sugar, they can still raise your blood sugar, contrary to their marketing. Even stevia is not safe. While it may seem natural, your body reacts to it in the same way as artificial sweeteners like sorbitol. Their long-term health effects are still under scrutiny. Researchers from Ben-Gurion University of the Negev (BGU) in Beersheba, Israel found that stevia can have a negative effect on gut health. Plus, recent studies have shown that sugar alcohols can still be partially absorbed, leading to unexpected spikes in blood sugar.

3. Swedish Smoke and Mirrors

Nick’s proudly flaunts its Swedish heritage, conjuring images of Viking warriors and pristine Nordic landscapes hoping you’ll associate it with Nordic health and wellness. But what does “Swedish” really mean for a protein bar? Aside from Nick’s nationality, these bars are not uniquely Scandinavian. They are made with no special Nordic ingredients or certifications. This “Swedish” angle feels like a marketing gimmick designed to elevate a product that is essentially on par with any other ultra-processed protein bar. You may find it cute, but don’t let it distract you from what’s actually inside.

4. “Better For You” Doesn’t Mean Good For You

Nick’s carefully avoids calling their bars “healthy,” opting for the vague term “better for you.” I kinda respect the attempt at a more honest approach. But better than what? A Snickers bar? Sure, these bars might edge out a candy bar nutritionally, but that’s a pretty low bar to clear (pun intended).

While these bars might have slightly better macros than a candy bar, that doesn’t make them good for you. Let’s dive into the macros in this bar.

5. The Ingredient Inquisition

While these bars boast “no added sugar” and a moderate amount of protein, a closer examination of the macros reveals a different story.

With 190 calories, 10 grams of fat, 15 grams of protein, 9 grams of fiber, and just 3 net carbs per bar, these numbers seem good at first glance. But how do they get there? With a crap ton of sugar alcohols–11g, to be precise–and a large dose of the synthetic fiber polydextrose. That’s fake food, not nourishment. While the amount of protein is significant, the problem is that the bars taste like protein powder.

I’m not the only one who was grossed out by the gritty protein powder taste:

And if you thought Nick’s Bars were unhealthy, read our review that proves Quest Bars are not healthy either.

What’s With the Protein?

The Triple Chokolad bar relies heavily on protein isolates like whey protein isolate, micellar casein isolate, and soy protein isolate. While these isolates offer a concentrated dose of protein, they’re also stripped of many beneficial nutrients found in whole food sources. Additionally, some people may experience digestive discomfort from these highly processed protein forms.

Next, we encounter a slew of binders, fillers, and emulsifiers. Soluble corn fiber, a type of processed fiber often used as a sweetener and thickening agent, raises concerns about its impact on blood sugar and gut health, according to Dr. David Friedman.

Tapioca starch, another filler, offers little nutritional value. And let’s not forget the gums: guar gum, xanthan gum, and locust bean gum. These additives help create a smooth, creamy texture, but their long-term effects on gut health remain a subject of debate.

The Takeaway
Nick’s Keto Protein Bars are a masterclass in clever marketing, masquerading as a healthy snack. But don’t be fooled – these are candy bars in disguise, packed with questionable ingredients and dubious health claims. These bars are designed to taste like candy, which makes them highly palatable and easy to overeat. If you’re looking for a truly nutritious and satisfying snack, skip the Swedish sham and reach for something that actually nourishes your body.

Why Real Ingredients Matter in Your Protein Bar

Many bars, like Nick’s Keto Protein Bars, try to pass themselves off as healthy by touting low net carbs and high protein. However, these numbers often mask a less appealing reality – a reliance on processed ingredients, sugar substitutes that wreak havoc on your gut, and a nutritional profile that’s closer to candy than a wholesome snack. Check out our low-carb protein bar reviews to see how Nick’s stacks up.

We developed the Human Food Bar, a plant-based bar packed with prebiotic fiber and resistant starch to nourish your microbiome and support optimal health.

Unlike Nick’s, our bar is inspired by the fiber-rich diets of our hunter-gatherer ancestors. We’ve carefully selected ingredients like tiger nuts, chicory root, and green banana flour to deliver a bar that’s not only delicious but also genuinely beneficial for your gut and overall well-being. Try it today!
