Top Products According to Experts

Best Keto Bars Reviews 2021 (UPDATED)

1. Keto Bars!

The original and one of the best: Keto Bars! are delicious.

They are, of course, high in fat at 21 grams, low carb at only 3 grams, with moderate amounts of protein per serving.

Unlike many keto products, they are also completely vegan. The ketogenic diet is notoriously difficult to follow plant-based, so this is a real treat.

Keto Bars! have a very simple but effective ingredients list. They only contain Peanut Butter, Chocolate, Coconut, Erythritol, Water, Salt and Stevia. You get a rich taste and quite dense, satisfying texture with this: they will melt in your mouth like any good chocolate would.

This being said, they are not particularly sweet. This mi-ght not be desirable for somebody first starting out on ketosis. If you’re used to sweeter foods, Keto Bars! may not be for you.

If you’ve been in ketosis for a while, they will be perfect. Your taste buds will have adapted to a lack of sugar and so the flavours in Keto Bar! will work really well for you. They will also hopefully stop you from getting any sudden hunger pangs or a desire for more sweetness.

2. Quest Nutrition Bars

Quest nutrition’s variety pack is a great resource for anyone looking for a high protein content in their diet. If you lift weights, involve yourself in any athletic endeavours, or simply need to up your protein intake, you should consider trying them.

They are lowish carb (4-6 grams per serving) and gluten free. You get around 20 grams of protein per serving, alongside 5-8 grams of fat.

There is no added sugar, which is surprising given their lovely, sweet taste.

One of the best things about this variety pack is the selection of flavours you get: Blueberry Muffin, Double Chocolate Chunk, Chocolate Brownie, Mint Chocolate Chip, Chocolate Chip Cookie Dough, Mocha Chocolate Chip, Chocolate Hazelnut, Oatmeal Chocolate Chip, Chocolate Peanut Butter, S'mores, Cookies and Cream, and White Chocolate Raspberry.

With this kind of offering, you need never be bored by flavours again.

3. Atkins Almond Butter Keto Bars

One of the biggest things to recommend these almond butter snack bars is the name behind them: Atkins are one of the biggest original hitters on the ketogenic scene. Dr Robert C. Atkins himself first popularised ketosis back in the nineties with his famous Atkins Diet.

There is more than just branding at work here. Again, it is a variety pack, meaning you get a choice of flavours. There are four here: Chocolate Almond Caramel, Vanilla Pecan Crisp, Lemon, and White Chocolate Macadamia Nut.

All of these are lovely. They are light and crisp, without any artificial colours, flavours or preservatives.

On top of this, the bars are made with real almond butter, ensuring that their nutritional value is excellent. You will get 12-16 grams of protein and 8-11 grams of fibre. Given how much keto diets can often lack adequate fibre levels, this is a huge plus.

Nutritional Value

4. Perfect Keto Bar

Perfect Keto advertise their keto bars as being protein packed. They are, in that they contain 10 grams per serving, but this is a little lacklustre compared to some other entries onto this list.

That 10 grams is very good quality, though. It comes from grass-fed bovine collagen. You also get 19 grams of fat, mostly from coconut oil MCTs.

All together, these will improve feelings of satiation whilst giving a very high-quality nutritional burst. There are no artificial flavors or preservatives, only good, clean ingredients. There is a selection of flavors available, all of which are lovely.

These flavors include cinnamon roll, salted caramel, lemon poppyseed, chocolate chip cookie dough, and almond chocolate brownie.

You can buy Perfect Keto Bars in bulk, with a discount for choosing 3 boxes of 12 for a total of 36 bars.

5. SlimFast Keto Fat Bomb Snacks

SlimFast are another big name in the weight loss supplement community. Though their methodology can be quite controversial in fitness circles, they have come out with a very good product with their Peanut Butter Cup Fat Bomb Snacks.

They are obviously Peanut Butter flavored. Though you may be disappointed if you think they will taste like Reese’s Pieces (they’re not quite that good!) they are still delicious.

Many products like these can end up being horrible with artificial tastes and chalky textures. Fat Bombs are not at all like that, SlimFast's are excellent tasting, with a very satisfying feel to them.

You get 14 servings per box. Each serving contains 90 calories, with 1 gram of carbs and 9 grams of protein.

They are not the best product on this list nutritionally, and they are pretty pricey, but these Peanut Butter Cups are a solid, well flavored option for a quick keto snack.

6. Bulletproof Collagen Protein Bar

Bulletproof’s Collagen Protein Bar are really effective and consistent. They have a shortbread taste and consistency that really does make them feel like a treat. The lemon cookie flavor is amazing, and they don’t tend to crumble, unlike many similar, competing products.

The collagen protein is from grass-fed cows, meaning that they have the same amino acid profiles found in bone broths. These are the building blocks of bone, joints, skin and muscle, making them essential to healthy living.

In addition to being perfect for keto diets, these bars are also completely gluten-free and are suitable for paleo followers. Bulletproof's Collagen Protein Bars also feature added Brain Octane oil and XCT oil to make sure that your energy levels remain steadily elevated throughout the day. These pure and natural oils offer a reliable and quick way of achieving ketosis.

7. Kiss My Keto Snacks Keto Bars

Kiss My Keto’s Keto Bars are very high in fat, with moderate protein levels and only 3 grams of carbs, making them the perfect accompaniment to any ketogenic diet.

The bars are available in three different flavors: Chocolate Cookie Dough, Chocolate Coconut and Chocolate Peanut Butter. Each one is delicious- far nicer than their competitors’ flavors. They are smooth and chewy, though the Cookie Dough flavor is perhaps slightly on the dry side.

These keto bars are also filled with MCTs, aiding your journey into ketosis. They also bring a good dose of prebiotic fiber.

Fiber can be a little hard to come by in ketogenic diets. It is crucial for a healthy gut, so needs to be included wherever it can be. It is also very filling, adding to the satiation that products like these bars should bring.

They are nevertheless perfect for any ketogenic diet.
