    Quest’s Strawberry Shortcake nails a dessert-like flavor while delivering 20 grams of complete dairy protein at 200 calories and just 2 grams of sugar—pulled off with a fiber-and-sweetener build instead of sugar.

  4. 4. Love Good Fats

What's in the Space Atlas bar?

Atlas Space is built on a grass‑fed dairy core—whey isolate and concentrate plus milk protein isolate—bound with almond butter and a touch of coconut oil. Instead of grain syrups or cane sugar, most carbs come from a refined soluble fiber, with real raspberries for tartness and monk fruit finishing the sweetness.

That fiber is typically made from corn or cassava and isn’t well digested, so it adds bulk and helps keep blood sugar steadier than regular sugar while monk fruit supplies the sweet.

The macros lean protein‑forward with moderate fat: 20g protein, 210 calories, 2g sugar. A short list of three functional additives keeps texture and sweetness in line without resorting to sugar alcohols.

What are people saying?

Main praise: Fans praise the sweet‑spot macros—20g complete protein at 210 calories—paired with a low‑sugar approach that skips sugar alcohols and delivers a soft, subtly sweet bite.

Main criticism: Critics cite batch‑to‑batch texture swings and a monk fruit aftertaste, note the premium price, and some avoid the added ashwagandha altogether.

Bottom Line

Reach for Space if you want a not‑too‑sweet, dairy‑based, low‑sugar bar that prioritizes clean ingredients and satiety. It fits best as a post‑workout protein hit or a steady mid‑day snack for low‑carb eaters who are fine with monk fruit and a touch of botanicals.

What's in the Crispy Cookie N!CK'S bar?

N!

CK’S Crispy Cookie builds its 16 grams of protein on a milk‑protein blend (whey isolate, caseinates, micellar casein) with a dose of collagen, then adds soy crisps for that cookie‑like snap.

The carbs are more engineered than rustic: soluble corn fiber (refined from corn starch) and inulin (a chicory root fiber) add bulk and sweetness with a little tapioca tucked into the crisps.

Fat skews confectionery—cocoa butter and shea lead, with sunflower and a touch of coconut—for a clean, chocolatey melt.

Sweetness comes from a modern trio of additives—erythritol (a fermented sugar alcohol), stevia (a leaf extract), and glycerin to keep it soft—so you’re looking at three additives used to keep sugars low without ditching texture.

At 210 calories and gluten‑free, it’s built to taste like a treat while sidestepping the big sugar swing you’d get from a cookie bar.

What are people saying?

Main praise: Fans say it’s the rare low‑sugar, gluten‑free bar that truly eats like a chocolate treat, with wafer‑meets‑cookie crunch and 16 grams of protein that actually satisfies.

Main criticism: Critics find the erythritol‑plus‑stevia sweetness too assertive, flag the ultra‑processed ingredient list and refined fibers, and note it’s off‑limits for some diets (collagen, dairy, soy, coconut) and sensitive stomachs.

Bottom Line

Low‑carb snackers and dessert‑leaning protein seekers who want something sweet, gluten‑free, and travel‑friendly without a full sugar crash.

What's in the Strawberry Shortcake Quest Nutrition bar?

This bar leans hard on dairy isolates: milk protein isolate and whey isolate, with a little casein, to pack 20 grams of protein into 200 calories. The strawberry shortcake flavor comes from real strawberries and natural flavors, with vegetable juice for color.

Sweetness isn’t from table sugar; it’s mostly erythritol (a zero-calorie sugar alcohol) and glycerin (a plant-derived syrup that keeps bars soft) plus a tiny bit of sucralose, which keeps sugar to 2 grams.

Carbs skew toward polydextrose—a manufactured prebiotic fiber—so it’s more low-glycemic engineering than oats-and-dates. Fats are a mix of almonds and confectionery fats (palm kernel oil and cocoa butter) that help the texture stay creamy and stable.

What are people saying?

Main praise: Reviewers say the protein-to-calorie math actually keeps them full—and the flavor leans convincingly dessert-like without a chalky finish.

Main criticism: The engineered sweeteners and fiber (erythritol, polydextrose, a pinch of sucralose) can taste artificial or cause GI grumbles for some, and stale bars can turn chalky.

Bottom Line

Choose this if you want a filling post‑workout or afternoon hold‑over that leans low sugar and you do fine with sugar alcohols and dairy. Skip it if you’re a whole‑foods‑only purist or have a sensitive GI tract.

What's in the Chewy Nutty White Chocolatey Strawberry Love Good Fats bar?

Love Good Fats’ Chewy Nutty White Chocolatey Strawberry leans dessert-first: dry-roasted almonds and cashews underneath, a white-chocolate-style coating with real freeze-dried strawberry on top. Protein comes from milk protein isolate plus crunchy fava-bean crisps, totaling a snack-size 8g, while carbs favor added fibers over sugar.

At 190 calories with 13g of fat and just 2g of sugar, it’s built for keto-style, fat-forward energy rather than a bulk-protein hit.

To pull off the creamy coat and low-sugar sweetness, the recipe uses roughly eight functional add-ons within a longer, about two-dozen-ingredient list—think refined fibers (to add bulk and gentle sweetness), glycerin (to hold moisture), and an emulsifier so the coating sets smoothly.

What are people saying?

Main praise: Fans say it tastes like a candy bar without the crash—nutty chew, creamy white-chocolate strawberry flavor, and 2g of sugar sweetened mostly by stevia and fiber rather than harsh sugar alcohols.

Main criticism: Critics report a dry, slightly chalky bite and a faint stevia aftertaste, with some stomach sensitivity to the chicory and corn fibers and skepticism from strict keto dieters about net-carb math.

Bottom Line

Best as a low‑carb, sweet‑tooth tamer or afternoon pick‑me‑up. Not ideal if you’re chasing a 20‑gram post‑workout protein hit.
