Short answer: ThinSlim Foods Zero Net Carb Plain Bread is a specialized loaf for shoppers who want a very low net-carb label and do not mind a dense, chewy slice. The current U.S. label lists 45 calories, 7 grams of fiber, 7 grams of protein, and 0 grams of net carbs per 28-gram slice. It is not a soft supermarket-style white bread, and it contains wheat. Our label-based verdict is 3.5 out of 5 stars.

The manufacturer calculates zero net carbs because the slice has 7 grams of total carbohydrate and 7 grams of fiber. If you track carbohydrates for a medical reason, use the method recommended by your clinician rather than relying on marketing language alone. Our guide to reading nutrition labels for net carbs explains the calculation and its limits.
What is in the loaf?
The current ingredient list begins with wheat protein isolate and vital wheat gluten. It also includes oat fiber, modified wheat starch, olive oil, chicory root, yeast, salt, and an enzyme. That combination helps explain why the loaf can deliver substantial fiber and protein while keeping the stated net-carb number at zero.
This is not gluten-free bread. ThinSlim lists wheat as an allergen and says the manufacturing facility also uses wheat, soy, peanuts, tree nuts, and sesame. Anyone managing an allergy should read the physical package and contact the company if cross-contact information affects their decision.
Texture and flavor: what should you expect?
ThinSlim describes the slice as denser and chewier than ordinary white bread, with a hearty texture, and recommends toasting it. That is an important expectation to set before buying. A formula built around wheat proteins and concentrated fibers is unlikely to feel exactly like a fluffy conventional loaf.
Independent customer comments on Walmart are mixed but broadly support that expectation. Some reviewers like it for sandwiches or with flavorful toppings. Others describe the plain slice as dry, firm, or too neutral and say light toasting improves it. Those comments are subjective, and many are older, so they should be treated as context rather than a controlled test of the current formula.
Our practical takeaway is simple: this loaf makes the most sense as a structure for fillings, spreads, eggs, or melted cheese. If you mainly want soft bread that tastes satisfying on its own, the tradeoff may feel too large.
How the nutrition compares with its purpose
The standout numbers are not just the zero-net-carb calculation. Seven grams of fiber and seven grams of protein in one 28-gram slice are substantial for a small piece of bread. Those quantities can make a slice feel more filling, but individual digestion and appetite responses vary.
The label does not turn bread into a free food. Portions, toppings, and the rest of the meal still matter. Two slices double every labeled quantity. Butter, mayonnaise, cheese, and sweet spreads can also change the meal far more than the bread itself.
Best ways to use ThinSlim Plain Bread
- Toast it lightly. This can give the surface more structure without turning the slice brittle.
- Use moist fillings. Tuna salad, egg salad, tomato, or a measured spread can balance a drier crumb.
- Build an open-faced meal. One slice topped with eggs or vegetables keeps the bread from dominating.
- Freeze extra slices early. Separate portions before freezing so you can thaw only what you need. See our guide to freezing low-carb bread.
The manufacturer says an opened loaf can be refrigerated for up to two weeks or frozen. Follow the use-or-freeze date on your package, and discard bread that develops mold, an off odor, or unusual moisture.
Who may like it—and who may not
Worth considering if you:
- want a bread with a zero-net-carb label;
- value a high-fiber, high-protein slice;
- prefer toast or sandwiches with strong fillings;
- are comfortable ordering a specialty loaf and freezing portions.
Probably skip it if you:
- need gluten-free or wheat-free bread;
- want a soft, airy supermarket white-bread texture;
- are sensitive to large amounts of added fiber;
- expect the bread itself to supply most of the flavor.
Our 3.5-star verdict
We use a 5-star rating system. ThinSlim Foods Zero Net Carb Plain Bread earns 3.5 out of 5 stars in this label-based assessment. Its nutrition label is unusually focused: a small slice with 7 grams each of fiber and protein and a manufacturer-calculated zero net carbs. The deductions are for the specialized, dense texture; the plain flavor described by some customers; and the fact that it is unsuitable for anyone avoiding wheat or gluten.
That score is an editorial judgment, not a laboratory result or an average of retailer ratings. Read how we evaluate products in the LessCarby editorial review policy.
Frequently asked questions
Is ThinSlim Zero Net Carb Bread really zero carb?
No. The current label lists 7 grams of total carbohydrate and 7 grams of fiber per slice. The company subtracts fiber to state 0 grams of net carbs. “Net carbs” is a calculation, not the total-carbohydrate line required on the Nutrition Facts panel.
Is it keto?
The label can fit many low-carb eating patterns, but “keto” depends on the rest of a person’s daily intake, goals, and response. The package numbers are more useful than a broad label.
Is it gluten-free?
No. Wheat protein isolate and vital wheat gluten are major ingredients, and the allergen statement says it contains wheat.
Should it be refrigerated?
ThinSlim says the unopened loaf uses modified-atmosphere packaging. After opening, refrigerate it for up to two weeks or freeze it, and follow the date printed on the package.
Bottom line
ThinSlim Plain is a purpose-built bread, not a seamless substitute for a fluffy white loaf. Its current label is compelling for shoppers who prioritize net carbs, fiber, and protein. The best use is toasted and paired with flavorful, moist ingredients. If texture is your first priority, buy with measured expectations.
