Best Low Calorie Keto Plant Protein Bars

Mosh’s Peanut Butter Crunch leans on dairy proteins—whey isolate, whey concentrate, and milk protein isolate—anchored by real peanuts for flavor and texture. It’s a trim 170-calorie bar with just 1 gram of sugar; sweetness comes from stevia and monk fruit rather than syrups.

Carbs are “engineered clean”: a refined, resistant tapioca fiber provides most of the bulk, with a little tapioca starch and plant-derived glycerin to keep the bar soft and cohesive. Fats land in the middle and are mostly peanut, with a touch of cocoa butter for creaminess.

Beyond that, you’ll spot a small Brain Blend and four functional add-ins—fiber to bulk and bind, glycerin to retain moisture, sunflower lecithin to emulsify, and stevia/monk fruit to sweeten—used for texture and stability rather than to goose the macros.

IQBAR’s Almond Butter Chip leans fully plant-based, anchored by pea protein and real almonds, with unsweetened chocolate and cocoa butter bringing the chocolate note. It’s built as a low-carb, higher‑fat snack that draws steady energy from nuts and cocoa fats rather than sugar, and it’s gently sweetened with a touch of stevia.

The ingredient list is short and largely pantry‑familiar, with minimal additives and no sugar alcohols. Bonus: you get a full day’s worth of vitamin E, plus meaningful iron and magnesium from the almond‑cocoa base.

Vegan bars that aim for keto are uncommon, and this one leans into the classic peanut-butter-and-chocolate lane with real peanut butter, peanut flour and extract, plus dark chocolate chips. Its 11g of protein comes from a plant blend—pea protein isolate tucked into cocoa crisps with brown rice protein—and a small boost from the peanut ingredients.

To keep sweetness in check, it uses soluble tapioca fiber and allulose instead of cane sugar, landing at 1g of sugar with a gentler blood-sugar impact for most people. Fats (11g) come mostly from peanuts and almonds, with cocoa butter lending that chocolate-chip snap and a modest iron bump from the cocoa and plant proteins.

A short list of refined helpers—glycerin for softness and sunflower lecithin for smooth mixing—keeps texture pleasant without piling on additives.

Atlas leans into peanut butter and dark chocolate but rewrites the sugar script. The protein is fully plant‑based—a rice‑and‑almond base with crunchy pea‑protein crisps—boosted by peanut butter and peanut flour.

The chew comes from soluble tapioca fiber (a refined binder from cassava) and a little plant‑derived glycerin to keep things soft, while sweetness relies on allulose, a low‑calorie sugar that behaves like the real thing, plus concentrated monk fruit extract.

Fats are mostly peanut‑driven, with small amounts of cocoa butter and coconut oil for structure. Net result: a vegan, gluten‑free, keto‑friendly bar with 15 grams of protein, 180 calories, only 0.

5 grams of sugar, and a quietly impressive 38% Daily Value of iron from the cocoa components.

Love Good Fats’ Chewy Nutty Peanut Chocolatey is a fat-forward, plant-based bar built around roasted peanuts and a chocolatey coating. Protein is modest at 7g, coming from peanut flour and peanuts with a little brown rice protein in the coating—so it stays dairy-free.

Carbs (15g) lean heavily on chicory-root inulin and soluble corn fiber, refined fibers that add bulk and a gentle sweetness while keeping sugar at 1g and the glycemic punch lower than a typical sugar-based bar.

The richness comes from peanuts plus a blend of peanut, coconut, MCT, and palm oils for a creamy, dessert-like bite and longer-lasting satisfaction.

A small set of functional add-ins (about four) support texture and shelf life—glycerin for moisture, sunflower lecithin to keep the chocolate smooth, stevia for sweetness, and tocopherols to help keep the oils fresh.

Built for efficiency, No Cow's Chocolate Salted Caramel leans on a pea-and-brown rice protein core and a chocolate shell made with alkalized cocoa for a smoother, less bitter bite. The salted caramel note comes from natural flavors and a pinch of salt rather than cooked sugar, so sweetness is handled by zero-calorie sweeteners.

You get 20 grams of dairy-free protein at 200 calories with 1 gram of sugar and 6 grams of fat, while most of the 26 grams of carbs come from refined soluble fibers.

It is a modern formula: 21 ingredients with about seven helper additives that keep the bar soft, sweet, and low in sugar, but also make it more processed than a date-and-oats bar.

Raw Rev’s Crunchy Peanut Butter & Sea Salt keeps things simple: real peanuts lead, a pea–brown rice protein blend supplies the muscle, and chia, flax, and hemp bring nutty crunch. It’s fully plant-based, higher in fats from nuts and seeds, moderate in protein, and low in sugar.

Sweetness and chew come from isomalto-oligosaccharides, a prebiotic fiber syrup made from tapioca that many people find steadier on blood sugar than cane sugar.

A little extra-virgin coconut oil helps it hold together, and the label stays short with just a couple of functional helpers (like sunflower lecithin), so it reads more pantry than lab.

Julian Bakery’s Dark Chocolate keeps things tight: plant-based protein from pea protein isolate, dark cocoa for flavor, and sweetness from monk fruit instead of sugar. Texture comes from a tapioca‑derived soluble fiber—its one functional additive—refined from cassava to create chew while contributing far fewer digestible carbs than flour or syrups.

Organic sunflower seed butter brings a gentle lift of unsaturated fats and a creamy backbone. The headline reads clean and clear: 20 grams of protein, 190 calories, and sugar turned down to a whisper.

You’ll see higher total carbs than some bars, but here much of that number is fiber doing structural work rather than quick energy.

Built like actual cookie dough, BHU Foods’ Chocolate Chip Cookie Dough bar starts with cashews and organic pea protein, so it’s fully plant‑based and dairy‑free. At 11 grams of protein and 200 calories, it behaves more like a steady snack than a post‑workout heavy hitter.

The energy tilts toward fats—cashews, certified‑sustainable red palm oil, and coconut‑derived MCTs—while carbs stay modest because the binder is soluble tapioca fiber, a refined fiber from cassava that helps keep blood sugar steadier than cane sugar.

Sweetness comes from monk fruit, not cane sugar, and the short formula relies on just two notable additives to do the smoothing and sweetening (sunflower lecithin and monk fruit extract), skipping sugar alcohols altogether.
