The Science Behind Low-Calorie Bread
For many on a low-calorie or low-carb diet, finding a satisfying bread can be a challenge. The promise of a full-sized, soft slice for only 40 calories seems like a dream come true. Schmidt Old Tyme, the producer of 647 bread, achieves this impressive feat by altering the bread's composition to significantly increase its fiber content. Fiber is a non-digestible carbohydrate, meaning it adds bulk and satiety without contributing to caloric intake in the same way as digestible carbs. This is a crucial distinction and the primary reason the calorie count is so low.
How Fiber and Modified Starch Lower Calories
The ingredient list for 647 bread reveals modified wheat starch and added fibers like oat fiber and powdered cellulose. Modified wheat starch is a type of resistant starch, which behaves more like fiber than a typical carbohydrate once consumed. It passes through the digestive system without being fully broken down, further reducing the number of absorbable calories. By replacing some of the standard flour with these fiber-rich components, the baker can produce a product that feels and tastes like traditional bread but has a significantly lower energy density. For example, a slice of traditional white bread typically has around 70 calories, while 647 bread consistently comes in at 40 calories.
Comparing 647 Bread to Traditional Breads
Let's take a closer look at how the nutritional profiles of 647 bread and a typical white bread stack up against each other. This comparison highlights why 647 bread is a popular choice for calorie-conscious consumers, but also points to some of the potential trade-offs.
| Nutrient | Schmidt 647 White Bread (per slice) | Traditional White Bread (approx. per slice) |
|---|---|---|
| Calories | 40 | ~70-80 |
| Total Carbohydrates | 14g | ~14-16g |
| Dietary Fiber | 8g | ~0.5-1g |
| **Net Carbs*** | 6g | ~14-15g |
| Protein | 2g | ~2-3g |
| Sodium | 140mg | ~150-180mg |
| Modified Ingredients | Contains modified wheat starch, powdered cellulose | Typically none |
*Net carbs are total carbohydrates minus dietary fiber and some sugar alcohols. For 647 bread, the net carbs are significantly lower due to the high fiber content.
The Verdict: Is 647 Bread Healthy?
The answer to whether 647 bread is truly healthy depends on one's nutritional goals. For individuals needing to reduce their calorie and carbohydrate intake, it offers a functional and satisfying alternative to higher-calorie bread. It also provides a significant boost in dietary fiber, which is beneficial for digestive health and can increase feelings of fullness. This high fiber content can also help prevent constipation, particularly for individuals who have undergone bariatric surgery.
However, some nutritionists caution that low-calorie breads often lack the full spectrum of micronutrients found in traditional whole-grain varieties. A 2018 Los Angeles Times article noted that while 647 bread provides fiber, it may have lower levels of other beneficial vitamins and minerals like folate and magnesium compared to minimally processed bread. Some critics also argue that relying heavily on processed, low-calorie alternatives rather than whole, unprocessed foods can be misleading for long-term health, as it may cause cravings for calorie-dense foods later on.
Ultimately, 647 bread is a tool. It effectively delivers on its promise of a 40-calorie slice and can be a strategic part of a calorie-controlled diet. As with any food, its healthfulness is determined by its role within a person's overall eating plan. For those seeking a high-fiber, low-carb bread without sacrificing taste or texture, 647 is a strong contender. For others prioritizing a more nutrient-dense, minimally processed diet, other bread options might be preferable.
How to Incorporate 647 Bread into Your Diet
- For Sandwiches: Use two slices for a satisfying sandwich without the high carb load of traditional bread. Try it with lean protein and plenty of vegetables to maximize volume and nutrition.
- For Toast: It toasts beautifully and serves as a low-calorie base for breakfast. Top with avocado, a sprinkle of seeds, or a small amount of low-sugar jam.
- For Snacking: Cut toasted 647 bread into strips or cubes for dipping into soup or healthy spreads like hummus. The high fiber content will help keep you feeling full.
- For Weight Management: The low calorie count makes it easy to fit into a weight loss plan. It allows for larger portions of a staple food without guilt.
Conclusion
Yes, 647 bread is actually 40 calories per slice, a fact supported by its nutritional labeling and composition. This is accomplished by replacing a portion of the flour with high-fiber ingredients and modified starches that reduce the number of absorbable calories and net carbs. While it is a useful tool for weight management and for those on low-carb or high-fiber diets, it is more highly processed and may offer a less complete nutritional profile compared to traditional whole-grain options. Making an informed decision means weighing the benefits of its low-calorie, high-fiber composition against the desire for a more nutritionally dense and less-processed bread.
- The Bottom Line: Is 647 bread actually 40 calories? Yes, the claim is accurate. Is it a perfect substitute for traditional bread? It depends on your dietary priorities, but for many, it offers a compelling balance of taste, texture, and macros that makes dieting easier.
