The Science Behind Extend Bars for Diabetics
Extend bars are built on a scientific foundation developed by endocrinologist Dr. Francine Kaufman, a former president of the American Diabetes Association. The core of their formulation is a blend of key macronutrients engineered to release glucose slowly into the bloodstream, thereby preventing the rapid blood sugar spikes and subsequent crashes often associated with high-sugar snacks. The primary active ingredient in this process is uncooked cornstarch, a resistant starch that resists digestion in the stomach and small intestine, allowing it to be absorbed over a prolonged period of 6 to 9 hours.
The Role of Uncooked Cornstarch
Uncooked cornstarch plays a critical role in how Extend bars affect blood sugar. Unlike other carbohydrates that are quickly broken down, uncooked cornstarch provides a slow and sustained release of glucose. This feature is particularly beneficial for managing blood sugar during periods of fasting, such as overnight sleep, or during prolonged physical activity. Clinical studies have shown that a snack containing uncooked cornstarch, like an Extend bar, can lead to significantly lower overnight and fasting blood glucose levels in individuals with type 2 diabetes compared to a placebo bar.
The Importance of Protein and Fiber
In addition to the patented uncooked cornstarch, Extend bars contain a significant amount of protein and fiber. This combination of protein, fiber, and slow-release carbs is vital for managing diabetes in several ways:
- Increased Satiety: Both protein and fiber are known to promote feelings of fullness and satisfaction, which can help curb appetite and prevent overeating at the next meal.
- Hunger Control: By slowing down digestion and providing sustained energy, this nutritional profile helps manage hunger pangs and unhealthy cravings.
- Weight Management: Better hunger control naturally supports weight management efforts, which is a crucial aspect of diabetes care.
Extend Bars vs. Other Snacks
It's important to compare Extend bars with other common snack options to understand their specific advantages for diabetics. Many regular protein and energy bars, for instance, contain high levels of sugar or fast-acting carbohydrates that can cause unwanted blood sugar spikes.
| Feature | Extend Bar | Other Diabetic-Friendly Bar (e.g., Glucerna) | Regular Snack Bar | Whole Food Snack (e.g., Nuts) |
|---|---|---|---|---|
| Primary Function | Long-acting blood sugar control | Meal replacement/portion control | Quick energy boost | Natural nutrients, fiber, fat |
| Net Carbs | Very low (0-1g) | Low to moderate | High, often from sugar | Low to moderate, depending on type |
| Glycemic Index | Low | Low | High, leads to spikes | Low to moderate |
| Protein | High (9-12g) | Varies (often 6g+) | Varies widely | Moderate to high |
| Fiber | High (4-7g) | Moderate | Low | High |
| Artificial Sweeteners | May use stevia/monk fruit (check label) | May contain some | Varies widely | None |
Considerations and Potential Downsides
While generally safe and effective for many, Extend bars are not a one-size-fits-all solution. As with any food product, individual responses can vary, and some customers have reported mixed results regarding taste or blood sugar effects. A few key considerations include:
- Artificial Sweeteners: Some formulations may contain sugar alcohols like maltitol, which can cause digestive issues like bloating or gas for sensitive individuals.
- Ingredient Quality: While they are formulated for glycemic control, not all ingredients may be considered 'whole food' by strict dietary standards. Reading the ingredient list is always recommended.
- Individual Variation: Clinical evidence supports the general efficacy, but as one blog reviewer noted, personal blood sugar response can differ, especially for individuals with type 1 diabetes on insulin. Always monitor your personal glucose levels when trying new foods.
Best Practices for Using Extend Bars
To maximize the benefits of Extend bars for diabetes management, consider the following best practices based on manufacturer recommendations and clinical studies:
- Bedtime Snack: An Extend bar before bed can help prevent nocturnal hypoglycemia and morning hyperglycemia.
- Pre-Exercise Snack: Eating one about 30 minutes to 1 hour before exercise can help sustain energy levels and prevent exercise-induced hypoglycemia.
- Between Meals: They serve as a great snack to bridge gaps between meals, controlling hunger and stabilizing blood sugar for up to 9 hours.

Conclusion
In summary, Extend bars can be a highly beneficial tool for diabetics looking to manage blood sugar and hunger effectively. Their patented formula, featuring uncooked cornstarch for slow glucose release, along with high protein and fiber, is clinically proven to help maintain stable glucose levels for an extended period. However, individual results may vary, and it is crucial to consider personal dietary needs, potential sensitivities to ingredients like sugar alcohols, and to consult with a healthcare professional before making changes to your diabetes management plan. When used mindfully as part of a balanced diet, they can be a great addition to a diabetic's snacking strategy.
