1. What are the ingredients that make ExtendBar so effective?

The key ingredient that makes ExtendBar so effective is uncooked cornstarch. Uncooked cornstarch is a very complex, low glycemic carbohydrate that digests and converts to blood sugar very, very slowly. Interestingly, once corn or cornstarch is heated or cooked, as it is in most of the food products we eat containing corn, it becomes a simple, high glycemic carbohydrate that works just the opposite, converting to blood sugar very rapidly. 

In ExtendBar, the uncooked cornstarch is combined with specific amounts of protein and fat to further slow the conversion to blood sugar. As a result, this unique ExtendBar combination – patented by Dr. Francine Kaufman, a physician specializing in metabolism – converts to blood sugar more gradually than any other snack and is the only one clinically proven to help stabilize blood sugar levels for up to 9 hours.

2. Do other snack bars contain these ingredients? 

ExtendBar’s formula is patent-protected, so no other bar contains this combination of ingredients shown to help stabilize blood sugar for up to 9 hours. Most other snack bars contain carbohydrates that aren't as long-acting and complex as those in ExtendBar, so they convert to blood sugar more rapidly and therefore can’t help stabilize blood sugar levels as long as ExtendBar.

3. Who can benefit from using ExtendBar? 

Anyone who would like to better manage their blood sugar levels can benefit from ExtendBar. 

People with diabetes – Whether you have Type 1, Type 2, gestational diabetes, pre-diabetes or insulin-resistance, ExtendBar is a great snack for you. It won’t cause the blood sugar spikes and swings other foods can, making it much easier to manage your blood sugar levels.

Individuals trying to lose or manage weight – When used as a between meal snack, ExtendBar can help you control your hunger for up to 9 hours, so you snack less and even eat an average of 21% fewer calories at mealtime. And because our low-carb ExtendBar flavors won’t raise blood sugar levels significantly, you won’t see a spike in insulin levels, so your body will be more likely to burn fat for fuel and less likely to produce and store fat. 

People who struggle with episodes of low blood sugar unrelated to diabetes – Even if you don’t have diabetes, you can still appreciate ExtendBar’s ability to help prevent low blood sugar for up to 9 hours, particularly if you

  • have Reactive Hypoglycemia 
  • experience low blood sugar during, or hours after exercise 
  • often skip a meal or go too long between meals 

Individuals who want to maintain a high energy level or improve their exercise performance and recovery – Because ExtendBar converts to blood sugar gradually over 9 hours, it provides you with a sustained supply of energy to help get you through the most physically demanding activity or your most hectic day and prevent the drops in blood sugar that can hurt your performance or slow you down.

4. When should I eat ExtendBar to get the maximum benefit?

When you should eat ExtendBar depends on which ExtendBar benefits are most important to you. 

To prevent low blood sugar – Eat an ExtendBar about an hour or two before you think an episode of low blood sugar is most likely to occur. If low blood sugar is a frequent problem overnight, take ExtendBar as a bed time snack. If it’s a problem during or after exercise or any physically demanding activity, take ExtendBar an hour before the activity begins. If you experience low blood sugar when you go too long between meals or skip a meal, use ExtendBar as a healthy between meal snack. 

To prevent high blood sugar in the morning – If you find you are going to bed with a normal blood sugar level, but waking with a blood sugar level much higher, eating ExtendBar as a bed time snack can help. In a clinical study where ExtendBar was used as a bed time snack, it was shown to reduce high morning blood sugar readings by an average of 28%. 

To help control your hunger – Use ExtendBar as a healthy between-meal snack, an hour or two after a meal, to keep your hunger from sabotaging you during your most vulnerable times of the day.

To maximize the benefits of your low-carb lifestyle – One of the key benefits of low-carb foods is that they won’t cause your blood sugar and insulin levels to spike, so your body is more likely to burn fat for fuel and less likely to produce and store fat. Because low-carb ExtendBar converts to blood sugar gradually over 9 hours – far longer than any other low-carb snack – it can extend these low-carb benefits for most of the day (if taken in the morning) and through the afternoon and evening (if taken just after lunch).

5. How does ExtendBar help to prevent low blood sugar (hypoglycemia)?

Unlike the carbohydrates in most foods we eat that convert to blood sugar within a couple of hours, the naturally complex carbohydrates in ExtendBar break down gradually to help prevent your blood sugar level from dropping too low for up to 9 hours. The torture test for this, not surprisingly, is at night while you sleep and can't replenish your blood sugar supply with food. In several clinical studies where the ExtendBar formula was eaten as a bedtime snack, the incidence of low blood sugar was reduced by 75%.

ExtendBar can help prevent low blood sugar any time it's likely to occur: 

Overnight - when your body has no supply of blood sugar from food. An ExtendBar before bed will help prevent low blood sugar throughout the night. 

During, and even hours after any vigorous activity or exercise - when your body uses a lot more blood sugar than normal. Eating an ExtendBar before the activity begins helps prevent low blood sugar during and even several hours after the activity ends. 

When a meal get delayed – Having an ExtendBar as a snack will help provide your body with the blood sugar it needs to function properly until you have a chance to eat a complete meal.

6. Can ExtendBar be used to treat low blood sugar episodes? 

Once an episode of low blood sugar occurs (a blood sugar level below 70mg/dl) you should consume a food or beverage with rapid-acting carbohydrates (10-15 gr) to bring your blood sugar quickly back up to normal. A 4 oz. glass of fruit juice or regular cola, a Tbsp of honey, an 8 oz. glass of nonfat milk, 6 pieces of hard candy (as long as it’s not sugar-free), 3 glucose tablets or a tube of glucose gel should work well. 

Since ExtendBar contains primarily the longer-acting carbohydrates, it is not an appropriate treatment for low blood sugar once it occurs. However, because the symptoms of low blood sugar can come on quickly and can be serious if not treated promptly, it is best to prevent low blood sugar from happening in the first place. Only ExtendBar helps provide a continuous supply of blood sugar for up to 9 hours – longer than any other snack –to help prevent episodes of low blood sugar.

7. How does ExtendBar help prevent high blood sugar (hyperglycemia) in the morning? 

What many people with diabetes don't understand is that having your blood sugar drop too low during the night, can actually cause your blood sugar to be high first thing in the morning, even before you eat. That's because as you sleep, your blood sugar level naturally drops. When your blood sugar level gets too low during the night, your liver releases glycogen (a stored form of glucose) into your blood stream. This quickly raises your blood sugar levels, often causing high blood sugar. 

When eaten as a bedtime snack, ExtendBar can help prevent your blood sugar level from dropping low enough to trigger the release of glycogen from your liver. In fact, in a clinical study where ExtendBar was eaten as a bedtime snack, morning blood sugar levels were an average of 28% lower.

8. How does ExtendBar help to suppress appetite? 

ExtendBar does not contain any ingredients that chemically suppress your appetite, like ephedra, caffeine or guarana. Instead ExtendBar helps naturally control your hunger by helping to prevent one of the key triggers of appetite – your blood sugar dropping too quickly or too low. 
Unlike ExtendBar, most common snacks contain carbohydrates that convert rapidly to blood sugar, sending your blood sugar soaring. Then within a couple of hours it crashes back down, triggering your appetite and you’re hungry again within just a couple of hours of eating. But ExtendBar contains a very slow-burning, long-acting carbohydrate which converts to blood sugar very gradually, helping to prevent your blood sugar from dropping low enough to trigger your appetite for up to 9 hours. In this way ExtendBar helps you control your hunger naturally. 

When clinically tested, eating ExtendBar as a between meal snack helped control appetite and reduced calories consumed at the next meal by an average of 21%. In addition to a more satisfied feeling throughout the day, many people have reported significant weight loss after using ExtendBar regularly.

9. How did you reduce the carbs in the Extendbars? 

We replaced some of the carbohydrates (rice crisps and fructose) with low glycemic carbohydrates (soy crisps, fiber and sucralose (splenda)). This not only reduced the net carbs in Low-Carb ExtendBar, but also added more fiber and protein to the formula.

10. In what way are Low-Carb ExtendBars better than other low-carb foods? 

Like ExtendBar, most low-carb foods have few fast-converting (net) carbs. So when you eat them, they won’t cause a big rise in your blood sugar. But that’s where the similarity ends. 
Unfortunately, other low-carb foods don’t contain sufficient long-acting carbohydrates to help maintain a healthy blood sugar level throughout the day or night like ExtendBar. So within a couple of hours your blood sugar drops, triggering your hunger and leaving you susceptible to episodes of low blood sugar. And many low-carb snacks are also high in fat and cholesterol and contain trans-fats, so they are not particularly good for your heart.

Low-Carb ExtendBar’s unique formula is patented for its ability to break down more gradually than other foods and release nutrients into your system more slowly. This slow conversion helps keep your blood sugar from rising too quickly, and continues to supply your body with the blood sugar fuel it needs to help prevent low blood sugar and keep your appetite under control for up to 9 hours. And because Low-Carb ExtendBar is also low in fat, high in fiber, and contains no cholesterol or trans-fats, it’s also deliciously heart healthy.

11. Can I lose weight using this product? 

Unlike many weight loss products on the market, ExtendBar does not "burn fat" or "speed up your metabolism", but it can help you to lose weight naturally in two ways. First, because ExtendBar converts so slowly to blood sugar, it won’t cause the spike in insulin production that encourages your body to produce and store fat. 
Second, because ExtendBar continues to provide you with a modest amount blood sugar for up to 9 hours, it works as a natural appetite suppressant, helping you to avoid unhealthy snacking between meals and eat less at meals. In clinical studies, people that used ExtendBar as a between-meal snack ate an average of 21% fewer calories at their next meal.
So when used regularly, ExtendBar can help you steadily lose weight in a more sustainable way.

12. What are the glycemic index and glycemic load of ExtendBar and why are they important? 

All ExtendBar flavors have a low glycemic index (GI), and our low-carb flavors also have a low glycemic load (GL), as shown below. The GI and GL provide good indicators of how much your blood sugar will increase within two hours of eating a particular food. This is very important to know when you’re trying to manage your blood sugar levels, whether it’s to better control your diabetes or manage your weight. 
Unfortunately, the GI and GL only measure blood sugar response for 2 hours – the time in which most commonly eaten carbohydrates digest. But a unique snack like Low-Carb ExtendBar, offers a benefit other low GI and GL foods can’t. It converts gradually to blood sugar over 7-9 hours. So it continues to help stabilize blood sugar levels long after other low-carb snacks have stopped. 

 

For perspective the following ranges are considered to be low, medium and high for the glycemic index and glycemic load.

The glycemic testing on ExtendBar was done by the Human Nutrition Unit at the University of Sydney in Australia -- the leader in glycemic index research and testing for over 10 years.  During that time they have determined GI values for more than 350 foods.  In the testing, glucose was used as the reference food, which has a glycemic index of 100.

13. How does ExtendBar improve exercise performance and recovery? 

With most types of exercise and strenuous physical activity, the body’s rate of using blood sugar (energy) increases both during the activity and for several hours after. And it’s not uncommon for a person to hit a point when their energy level suddenly drops and they experience symptoms of low blood sugar (headaches, feeling light-headed, weak, shaky, or inability to focus).

Because ExtendBar converts to blood sugar over 7-9 hours – more slowly than any other snack – it can supply the energy you need for even the most physically demanding activity. And ExtendBar continues with its energy supply for several hours after, while your body works to adjust its blood sugar needs back to a normal level.

14. Is the product kosher? 

Yes, most of our flavors are kosher (with the exception of our Apple Cinnamon Delight). The kosher symbol can be found on the back or side of the carton and on the individual bar wrappers as well.

16. Is the product gluten free? 

We have recently added two flavors to our line up that are gluten-free – Low-Carb Chocolate Delight and Low-Carb Apple Cinnamon Delight. The rest of our flavors are not gluten-free, since they contain a very small amount of barley malt extract.

17. Should I consult a physician before I use ExtendBar? 

ExtendBar fits into the FDA’s medical food classification, which simply means that it has been clinically shown to help in the dietary management of a medical condition. In ExtendBar’s case, clinical studies have shown it to be very beneficial in the management of diabetes and low blood sugar (hypoglycemia) because of its ability to help stabilize blood sugar levels. 
While ExtendBar does not require a prescription, if you have diabetes it is important to account for ExtendBar's calories, carbohydrates, etc. in your normal meal planning. Your health care professional can best aid you in this process. Please feel free to have your healthcare professional review the ExtendBar website for further information.
