Factors To Consider When Buying Low-Carb Protein Bars

When you’re in a rush to work or when you’re late for your gym session, you’re probably looking for a quick snack to munch on to give you enough energy that you need. More often than not, protein bars can come to your options, most especially if you’re monitoring your health.

These on-the-go bars really promise each and everyone of us the nutrients it wants to help us satisfy our hunger and at the same time build our muscles. However, since protein bars are not made the same, there are still considerations to look out for.

These factors don’t dictate whether your low-carb protein bar is a good or bad purchase. Rather, it helps you assess what protein bar best suits you.

Of course, you still have to buy from the trusty brands because there are protein bars that are candy bars in disguise. This type of protein bar is what you should look out for most especially when you’re on a weight loss journey.

So, use this checklist when you’re deciding which protein bars to invest in. I mean, you don’t want to be buying protein bars with empty calories and odd protein sources, right?

Nutritional Content

Other than a good and easy-to-read nutritional fact or instructions, the nutritional content of the protein bar is extremely important because this is definitely the cornerstone of your purchase. Most likely, you’re buying a protein bar to satisfy your hunger while still being healthy.

Protein bars are made for different individuals. There are protein bars that can be for people who want to gain weight and there are protein bars that are specifically made for vegans. Regardless, you should always read the nutritional content.

Protein bars do not only offer convenience, but they also offer good nutrients that you can stuff in your body. However, you don’t want to be compromising your health for easy access to nibbles.


Since we’re talking about low-carb protein bars. You should definitely look closely on the carbohydrates part of the nutritional facts.

At first taste (or glance), you might think that your protein bars are low-carb because of the small sugar content. But, this could be very misleading.

Carbohydrates may be the first component of the protein bar. You might think that you won’t be gaining much weight because your bars don’t taste sweet enough, but kid you not, carbohydrates can be really tricky.

You should look for bars that primarily contain protein, fruit, vegetable, or nuts. Carbohydrates can be in a facade of a different name like dextrose, molasses, honey and agave nectar, or others. 

If you want a very low-carb protein bar, then I suggest looking into ProSource Protein Bar. This protein bar has only 9g carbs per bar, which is already pretty low.

Sugar (Sweeteners and Seasonings)

When you look at the back of the packaging, you’ll immediately notice the types of sugar that were used. Though sugar can be good when taken in a small amount, there are just sugars that are pretty undesirable.

Ingredients like sucrose, corn syrup, and high-fructose corn syrup are the types of sugar that are usually incorporated in your protein bars in a high dosage. You should definitely watch out for that!

There are also sugar alcohols and artificial sweeteners like maltitol. Though these are relatively safe, they can have a downside too.

Artificial sweeteners and flavorings (or seasonings) can contribute to calorie content and could elevate your blood sugar. So, if you’re diabetic or you’re closely monitoring your glycemic index, then you might want to aim for no more than 6-8g of sugar.

Bulletproof Collagen Protein Bars is a good recommendation if you want a low sugar low-carb protein bar (2g).


Did you know that protein bars can deceive you? Some protein bars contain more sugar and calories than protein, defeating its initial purpose. A good protein bar must contain at least 5g of protein.

Your protein requirement is, of course, varying from your exercise goals to your bodily needs. Athletes may need more protein compared to an average individual.

If you’re strict with your weight loss journey, you might want to consider the 2:1 ratio of protein to carbs. 1:2 ratio is required, on the other hand, for recovery after a workout. And if you’re a long-endurance athlete, 1:4 may be the ideal ratio.

FitJoy Protein Bars is a good option for a high protein count (20g). And if you prefer plant-based protein, then you might want to look into Healthy Valley F-Factor Fudge Brownie Bar (20g).


You might want to give yourself a little assessment. Since you’re buying a low-carb protein, I’m assuming that you’re closely monitoring your weight gain. If this is the case, then a low calorie content protein bar should be your go to.

A great choice of a bar would be 140-200 calories per bar for women and 170-300 calories per bar for men. Of course, this is only for the average body. Different bodies and lifestyles require a different calorie requirement.

For a low calorie count in your protein bar, you might want to look into Orgain Organic Plant-Based Protein Bar (150 cal).


If you find trans or saturated fats in your protein bars, then you better run! Your protein bars must not contain any of these fats. The healthy fats, like nuts, must be the type to be incorporated in your bars.

You should avoid vegetable oils like soy, rapeseed, palm, sunflower, linseed, and sesame oil. These are the fats that are quite unhealthy for your diet.

Instead, look for healthier fat like coconut oil, nuts or nuts better, and seeds like chia. These are significantly better than the other types of fats.

If you’re eating your low-carb protein as a post-workout meal, you should really look for the healthier fat because it can slow down the release of carbs into the bloodstream. Ideally, this should be less than 3g.

Bulletproof Collagen Protein Bars are just not known for their collagen content, but also for their coconut oil content as their fat source.


More than 6g of fiber is ideal when you want this snack to be your stomach filler when waiting for your next meal. This helps you stay full longer. Moreover, this promotes a healthy gut function as well.

Fiber is also known as a great help when controlling your blood sugar. To give you an easier find, bars that are fruit and nut based are usually loaded with fiber.

F-Factor Fudge Brownie Bar is a product you might want to check into because of its high fiber content (20g).

Flavor and Texture

When you’re only beginning to eat healthy or when you just don’t really like the taste of the healthy and nutritious foods (I get it, they often taste bland or grassy, right?), flavor must be highly considered.

Eating healthy  is not just about choosing what is nutritious and what is the best, but it is also about choosing what makes you happy and enjoy eating. After all, eating is one great leisure, isn’t it?

You should look for protein bars that are good in your palate and really gives you the joy that you want. Protein bars aren’t just there to keep you full, but it should also give you the little serotonin that you need.

I recommend looking into SimplyProtein Bar for their exceptional taste. This is a great protein bar for picky eaters and those who are only beginning to indulge in this kind of lifestyle.

Frequently Asked Questions On Protein Bars

Is it okay to eat a protein bar every day?

Not really. It is still healthier to slow down and eat real food, instead of going for the on-the-go snacks. Real food is still the best main source of protein like cottage cheese, hummus, black beans, tofu, and whatnot.

Protein bars are a good addition to what you eat, but never an alternative. It is basically just there to help you with your hunger, but it should not be your main meal.

Are protein bars a good alternative for snacks?

This is a good snack option. However, you must still take note that they have a lot of fillers in them and these ingredients do not have the complete protein source.

You should still look into eating fruits and other whole food like yogurt for your snacks. You get more nutrients from whole and real foods instead of the processed, packaged snacks.

Are protein bars recommended for people losing weight?

This is recommended as a small snack, but definitely not a meal replacement. Of course, you’ll really lose weight if you’re only eating a 150-calorie protein bar compared to a 800-calorie meal. However, this is unhealthy and should not be practiced.

Your body still needs the nutrients it requires, most especially when you’re working out. Also, always read the nutritional information for the hidden fillers or bad fats.

Wrapping Up

It is important to know what you’re putting inside your gut. Hence, remember that even though these bars are deemed low-carb, whole and real food are still more important and healthier than these.

Nutritional information is still the best way to know if your low-carb protein bars are the best option for you. The short descriptions plastered on the front of the packaging can be really deceiving if you don’t read the numbers at the back. 

There are unhealthy fats and deceiving carbs that can be hiding in your bars. Remember to always check reviews and the nutritional facts before buying these bars. Take note that what you see isn’t always what you get!
