One Bars Review

One Bar

Definitely Not the One (Avoid this Low-Carb Protein Bar)

Right when I thought things couldn’t get any worse with Fake Food protein bars, I came across One Bars, the worst low-carb bars available. Seeing as I’ve tested several dozen bars, that’s really saying something.

Fittingly for its name, the One Bars gets just a single star.

One look at the inside of this bar and you can immediately tell One Bars are not healthy. This bar is most certainly not going to be good for you. Popular flavors include Glazed Donut and Birthday Cake. Who eats these things?!

Artificial everything

They contain isomolto-olligosacharides (ISO), the fake and misleading fiber that Quest Bars got sued over. One of the many problems with ISO is that it’s partially digestible, increasing net carbs. One Bars also contain Carnauba Wax, which is what I use to polish my car (no, really).

I included them here because, despite their inferiority, they’re selling well on Amazon and anyone in the market for a keto-friendly protein bar could come across them.

Sadly, taste and price alone are enough to earn bars high ratings on Amazon. The problem is that the people these bars are being marketed to are trying to be healthy. Beware, keto friends: these could be the unhealthiest bars money can buy.

One Bars come in the following flavors: • Birthday Cake • Almond Bliss • Maple Glazed Donut • Peanut Butter Pie • Blueberry Cobbler • Peanut Butter • Peanut Butter Chocolate Cake

What ingredients are in One Bars?

One Bar Ingredients include: protein blend (whey protein isolate, milk protein isolate), isomalto-oligosaccharides (prebiotic fiber from vegetable source), vegetable glycerin, maltitol, palm kernel oil, sunflower seed butter, natural flavors, nonfat dry milk, soy lecithin (an emulsifier), sea salt, tapioca starch, calcium carbonate, colored with beta carotene, distilled monoglycerides and sucralose.

Are One Bars keto?

Not really. They're low carb but not high in fat, and they're loaded with unhealthy ingredients so they're not really good for any human. See our review of the best keto friendly protein bars for 2022.
