Many people like to keep some of their favorite snack foods that you keep around for times when hunger appears but it's important that we choose the right snacks because some of them can don’t always have the nutritional profile that they should.

Protein shakes have been around for a while and are very popular but let's face it they aren’t all created equally.

Some of them taste great, but others can make you feel bloated after just one sip. Others can even cause an upset stomach or days of constipation.

One Protein Bar Review

One Protein Bars are made with real ingredients including pea protein isolate, whey protein concentrate, milk protein isolate, and egg whites.

They also contain natural flavors and sweeteners like agave nectar and stevia. These bars vegan friendly and are gluten free.

A One Bar comes in over 15 different delicious flavors. One Bars make a great pre-workout, in-between meal, or post workout snack.

You can enjoy them guilt-free because they are made with natural ingredients and contain less than 5 grams of sugar per serving.

If you're looking for a healthier alternative to a protein bar One Bar is a great option. Let’s look in a little bit more detail.


Protein is the main ingredient in a One Bar.

A One Bar contains enough protein for your bodies needs but you shouldn’t go overboard with protein as too much protein could cause you to store fat instead of burning it.

In the One Bar milk and whey proteins are blended together in a ratio that works best for your body.

Unfortunately the many versions of One Bar isn't an option if you are a vegan. However, the new One Plant Protein bar does not contain animal products and therefore is vegan friendly.

One Bar has also removed the sugar alcohols that give them their sweetness. These sugars are often associated with bloating and other digestive problems.


If you are following a calorie controlled diet then bear in mind there are different calorie counts on the labels of the bars. So you will need to calculate them yourself.

One of the most popular bars is the 'Almond Bliss' - Here is a detailed breakdown of the nutrition information for each bar:

  • Calories: 240
  • Proteins: 20 grams
  • Total Fat: 9 grams Sodium 115 mg
  • Total Carbs: 22 grams
  • Dietary Fiber: 3 grams (including both soluble & insoluble fiber)
  • Sugar: 1 gram
  • Sugar Alcohol: 6 grams


Is the protein 1 bar actually healthy for you? Some protein bars on the market may have a lot of added sugars and a nutrition profile similar to a candy.

You should avoid these because they contain a lot of sugar and not enough nutrients. One protein bars are low in sugar and have a great nutrition profile.

These bars provide a mix of essential amino acids, vitamins, minerals, fiber, antioxidants, and other health benefits.


One Bars come in various flavours ranging from birthday cake to Blueberry Cobbler, and with over fifteen flavors available, it can satisfy just almost any taste bud.

Unlike many other bars on the market, One Bars do not contain the strong aftertaste that comes from using sugar alcohols.

For a tasty treat, all One Bars feature a rich layer of frosting and soft cake like texture. If you are craving a delicious protein bar, One Bars should definitely be your first choice.

Weight Loss Friendly?

One Bar is made with real fruit, nuts, seeds and chocolate — all natural ingredients that are packed full of fiber, vitamins and minerals.

If you're hungry after a workout, snack on a protein bar instead of grabbing something unhealthy at your desk.

Protein bars are a convenient option and will give you the right amount of nutrition to refuel.

A post workout snack should consist of a mix of protein, carbohydrates, and fats to help rebuild muscle tissue and replenish glycogen stores.

These snacks are easy to grab and won't require any preparation time. This make them the ideal addition to any weight loss programme.

Muscle Gain

Protein is an essential nutrient for all living organisms.

It plays a role in maintaining healthy bones and muscles, preventing disease, producing hormones, and helping our bodies repair themselves after injury.

Protein also helps us feel full longer and aids in digestion. If you’re trying to add muscle mass, consuming enough protein while exercising will help you achieve your goals.

Eating at least 1 gram of protein per kilogram of bodyweight each day may be beneficial.

However, if you’re not currently eating enough protein, you can start slowly and gradually increase your intake until you reach that amount to help prevent any unpleasant side effects.

Meal Replacement

Protein Bars, including the One bar, are often seen as a replacement for meals, especially breakfast.

You should remember that Protein bars are not a substitute for eating whole foods, though they can be a great addition to your diet if you need a quick pick me up.

If you’ve got time to sit down and enjoy a proper meal, then a protein bar isn’t going to cut it. However, if you’re running out the door, grabbing a protein bar could be just what you need.

Some protein bars are high in calories and contain added sugars, making them less ideal for weight loss.

Others are low in calories, and lower in sugar, making them a healthier choice.

Weight Gain

Some protein bars have very high amounts of added sugar, making them calories dense. While others may not be nutritionally balanced. Others may be low in fiber.

Protein bars are generally considered healthy, especially when compared to other snack options.

However, if weight gain is your motivation you can can easily gain weight with the higher calories options.


Birthday Cake

The birthday cake flavour One bar is a great tasting option. These bars have a nice texture and are easy to chew.

They don't leave my mouth feeling dry like other protein bars tend to. They also have a delicious chocolate frosting which isn't overpowering, and it adds a nice touch to the overall experience.

Overall, these bars are a great tasting treat that you could enjoy anytime of the year.

Cinnamon Roll

One Bar nailed another tough flavor. Their Cinnamon Roll Bar has a nice layer of frosting on top, which adds an extra crunchy bite that crumbles away when you bite down on it.

In terms of cinnamon flavor this bar doesn't seem to have enough cinnamon flavor to make up the lack of sugar, so overall, It would be recommended for anyone who likes a subtle cinnamon taste.

Almond Bliss

This bar is surprising because it had a slight coconut flavor, but it doesn't overpower the other flavors.

The almond pieces add a great crunchy texture, and they are also sprinkled throughout the bar. This bar could benefit from adding even more nuts, but it is still enjoyable.

Cookies And Cream

These two flavours are particularly popular. It really hits all the right notes. The vanilla bean ice cream is also very good. Both of them have an excellent aftertaste.

Chocolate Brownie

If you love brownies and chocolate, then this bar should be right up your alley. The chocolate flavor is very similar to a real brownie.

The icing provides just enough sweetness to round out the flavor profile. The best part of this bar is the texture. It feels like a real brownie.

Chocolate Chip Cookie Dough

Many choc chip cookie bars out there offer a lot of sugar, but not enough nutrition. Most of them also have a very strong cookie dough flavor, which isn’t necessary.

This bar offers a great amount of protein, but still keeps the calories low. The best thing about this bar is its unique texture. It tastes like a cookie dough bar, but a healthy version.

There aren’t any chewy pieces of cookie dough, just soft chunks of high quality protein. So overall, this bar is an awesome option if you’re looking for something sweet and nutritious.

Maple Glazed Doughnut

If you love doughnuts this is the flavour for you. It tastes like a real doughnut along with that unmistakable maple flavour. A maple doughnut that doesn’t contain any artificial ingredients.

Just pure maple goodness. For the most part the taste isn't overly sweet, like you might expect with an artificial sugar.

Blueberry Cobbler

This flavor doesn’t taste like anything else out there. That is because this is a unique combination of ingredients that nobody else has ever put together before.

If you are looking for something different, then this is the perfect choice for you.

In Summary

As protein bars go, the One bar is a great nutritional choice with fantastic flavours - the perfect ‘on the go’ treat!
