Fit Butters High Protein Nut Butter and Protein Peanut Butte
✅ PROS
- Delivers 12-14g protein per 2-tbsp serving — roughly double regular peanut butter — with only 2g net carbs
- Uses whey protein isolate and peanut flour rather than cheap fillers like maltodextrin or soy protein isolate
- No stirring required — the oil doesn't separate like natural peanut butters, so it's spoon-ready every time
❌ CONS
- Texture is noticeably drier and grittier than standard peanut butter; several buyers describe it as 'chalky' or 'powdery'
- Sweetener aftertaste is polarizing — the stevia/monk fruit blend bothers some people more than others
- At roughly $1.50-$2.00 per ounce, you're paying a heavy premium for protein that's easy to get elsewhere
The Verdict
The 3.4-star reality check on Fit Butters: protein-packed, but is it actually good?
Here’s the honest pitch: Fit Butters solves a real problem. You want peanut butter’s taste and satiety, but you’re tracking macros and regular PB’s 8g protein per serving isn’t cutting it. This spread doubles that number to 12–14g per 2-tablespoon serving while slashing carbs. On paper, it’s a perfect fit for keto, low-carb, or high-protein diets. In practice? The 170 ratings averaging 3.4 stars tell you this isn’t a slam dunk.
What you actually get
Two 16-ounce jars (or a single jar depending on the listing you land on) of a peanut-butter-like spread with roughly 190 calories, 14g protein, 14g fat, and 2g net carbs per serving. The ingredient list is respectable: peanuts, whey protein isolate, peanut flour, and a stevia-monk fruit blend. No palm oil, no maltodextrin, no soy isolates — which is better than most competitors in this category.
The texture problem nobody warns you about
This is where the product splits opinion. Because they use peanut flour and whey isolate instead of just grinding whole peanuts, the spread is drier and less creamy than Skippy or Jif. Several reviewers describe it plainly: “The texture is very dry and almost sandy.” Another notes, “It tastes like peanut butter powder mixed with water — not like actual peanut butter.” That’s not a universal experience — some buyers find it perfectly spreadable — but it’s common enough that you should expect it.
The flip side: because there’s no oil separation, you never have to stir. That’s a genuine convenience win over natural peanut butters like Adams or Smucker’s Natural.
What buyers consistently praise
The macro profile is the headline. One verified buyer puts it simply: “Best protein-to-calorie ratio I’ve found in a spread.” Others specifically call out how well it works in smoothies and overnight oats, where the drier texture actually disappears into other ingredients. The chocolate flavor gets notably more love than the original — several reviewers call it a genuine treat rather than a compromise.
Where it falls short — honestly
Beyond texture, the sweetener aftertaste is the second major complaint. Stevia and monk fruit have that cooling, slightly bitter finish that some people can’t get past. If you’re sensitive to artificial sweeteners, this will likely bother you more than the texture.
The price is the third issue. At typical pricing around $12–$16 per 16-ounce jar, you’re paying $0.75–$1.00 per ounce. Regular peanut butter costs $0.15–$0.25 per ounce. You’re paying a 4–5x premium for the protein bump — and you could achieve similar macros by mixing regular PB with a scoop of whey for far less money.
Who should buy this
- Keto dieters who want a PB substitute without the sugar carbs — this fits cleanly.
- Bodybuilders on strict cut macros who need protein density in a spread format.
- Smoothie makers who will blend it into shakes where texture doesn’t matter.
Skip it if you want a direct PB replacement for sandwiches, you’re sensitive to stevia aftertaste, or you’re on a budget. The value math doesn’t work for casual use.
FAQ
Q: Does this need to be refrigerated after opening? — No, but it stores fine in the pantry. Refrigeration makes it harder to spread, so keep it at room temp.
Q: Can I bake with this? — Yes, but adjust moisture. The drier texture absorbs more liquid, so add an extra tablespoon of oil or milk per 1/2 cup used.
Q: How does it compare to PB2 powdered peanut butter? — This is creamier than rehydrated PB2 and has a better protein-to-carb ratio, but PB2 is significantly cheaper per serving.
The verdict: 3.3/5 — Buy it if macros matter more than mouthfeel
Fit Butters is a legitimate macro tool, not a junk product. The protein-per-serving is real, the ingredient list is clean, and the no-stir convenience is a genuine plus. But the dry texture and sweetener aftertaste are dealbreakers for a meaningful portion of buyers — and the price demands you actually use it daily to justify the premium. If you’re blending it into shakes or spreading it thin on rice cakes, it works. If you want a spoonable peanut butter experience, save your money and buy the real thing.
