What are "Net Carbs" and How are They Calculated?
The term "net carbs" refers to the carbohydrates in a food that the body can actually digest and convert into glucose for energy. This contrasts with "total carbs," which includes all types of carbohydrates. The most common calculation is:
Net Carbs = Total Carbohydrates - Dietary Fiber - Sugar Alcohols
Dietary fiber is included in the total carbohydrate count on a nutrition label but is largely indigestible by the human body and does not affect blood sugar in the same way as digestible carbs. This is the fundamental principle that allows products like Hero Bread to advertise a low net carb count.
The Role of Resistant Starch
For Hero Bread, the magic ingredient is resistant wheat starch. Resistant starch is a type of dietary fiber that acts as a prebiotic, meaning it feeds the good bacteria in your gut. When resistant starch passes through the small intestine largely undigested, it prevents the sugar from being absorbed into the bloodstream. This significantly lowers the overall net carb value. The manufacturer uses this scientific basis to offer a bread that has the taste and texture of traditional bread but with a drastically different nutritional profile.
The Truth Behind Hero Bread's "0 Carb" Claim
It is important to note that the 0g net carb claim typically applies to specific products, such as the Classic White sliced bread. Not all of Hero Bread's products are zero net carb. For example, the Seeded bread is listed as 1g net carb per slice, and the Everything bagel contains 5g net carbs.
- Hero Classic White: Contains 11g total carbohydrates and 11g dietary fiber, resulting in 0g net carbs.
- Hero Seeded Bread: Has 13g total carbs and 12g dietary fiber, for 1g net carb.
This highlights the necessity of reading the nutrition label carefully, as the net carb count can vary between different products from the same brand.
The Blood Sugar Question: Individual Responses May Vary
While the resistant starch formula can effectively reduce net carbs, reports from some keto dieters suggest that Hero Bread can still cause a blood sugar spike. For example, one Reddit user reported a significant blood sugar increase after consuming two slices. Hero Bread has stated that it has not conducted clinical studies on blood sugar impact and advises users to consult a healthcare professional.
This individual variation can be influenced by several factors:
- Gut Microbiome: The composition of a person's gut bacteria can affect how efficiently resistant starch is processed.
- Insulin Sensitivity: People with insulin resistance, such as those with Type 2 Diabetes, may be more prone to blood sugar fluctuations from foods that cause even minor glucose absorption.
- Serving Size: The impact on blood sugar can increase with larger portion sizes. Consuming more than one slice at a time could push some individuals past their tolerance threshold.
This phenomenon illustrates a crucial point in personalized nutrition: food is not a one-size-fits-all solution, and a product that works for one person may not work for another. It is advisable for individuals with diabetes or those following a strict ketogenic diet to test their own blood sugar response to this product.
Comparison Table: Hero Bread vs. Other Options
To better understand Hero Bread's place in the market, here is a comparison with a typical regular white bread and a common nut-based keto bread.
| Feature | Hero Bread (Classic White) | Top-Selling Regular White Bread | Nut-Based Keto Bread (Average) |
|---|---|---|---|
| Net Carbs (per slice) | 0g | ~13g | ~1-2g |
| Total Carbs (per slice) | 11g | ~14.5g | ~5-6g |
| Dietary Fiber (per slice) | 11g | ~1.5g | ~4g |
| Primary Flour/Starch | Resistant Wheat Starch | Wheat Flour | Almond/Coconut Flour |
| Protein (per slice) | 5g | ~2.5g | ~4-5g |
| Allergens | Wheat, Soy, Milk, Eggs, Sesame (possible cross-contamination) | Wheat | Tree Nuts (Almond), Coconut, etc. |
| Taste/Texture | Designed to mimic traditional bread | Standard soft white bread | Varies; often denser/different texture |
| Cost | Generally more expensive | Inexpensive | Varies; often premium priced |
The Pros and Cons of Hero Bread
Hero Bread has its benefits, particularly for those seeking a low-carb alternative that closely resembles the taste and texture of regular bread. However, it also has potential drawbacks that consumers should consider.
Pros:
- Impressive Macros: The Classic White offers 0g net carbs, 0g sugar, 5g protein, and 11g fiber per slice.
- High Fiber Content: The high fiber from resistant starch is a benefit for satiety and digestive health.
- Familiar Taste and Texture: Many reviewers praise its likeness to traditional bread, which can aid in sticking to a low-carb diet.
- Versatile: It works well for sandwiches, toast, and other applications where regular bread is used.
Cons:
- Potential for Blood Sugar Spikes: Some individuals, especially those with diabetes or strict keto followers, have reported unexpected blood sugar reactions.
- Not Gluten-Free: Because it is made with wheat-based ingredients, it is not suitable for individuals with gluten sensitivities or Celiac disease.
- Expensive: Low-carb specialty products often come with a higher price tag compared to conventional bread.
- Ultra-Processed: Critics point out that its reliance on modified starches makes it an ultra-processed food, which may not align with a whole-foods approach to health.
Conclusion: Is Hero Bread Right for You?
Hero Bread's claim of 0 carb for specific products is technically accurate under the net carb definition, thanks to the use of resistant wheat starch. For many seeking a lower-carb bread substitute with a familiar taste, it can be an effective tool. However, its success is not universal, particularly for blood sugar control, with individual responses varying widely. For those with medical conditions like diabetes, it is crucial to proceed with caution and monitor your own reactions.
For a more holistic approach to health, focusing on whole foods and complex carbohydrates might be a better long-term strategy. However, as a transitional product or an occasional treat for those on a low-carb diet, Hero Bread can satisfy the craving for traditional bread without a significant glycemic load for many individuals.
Further research on dietary fiber and glycemic index can provide additional context.

The Final Word
Ultimately, whether Hero Bread is a suitable choice depends on your specific dietary goals, your body's individual response, and your budget. The 0 carb claim is a result of a specific formula, not a complete absence of carbohydrates, and its health implications require careful consideration.
