Enhance your fasting with the unique and premium formulation of the ProLon® Fasting Bar

Why ProLon fasting bar?

Fast on your own terms. You can eat a Fasting Bar and extend your fasting window! Who wouldn’t want to actually eat something as opposed to just drinking water?

Intermittent Fasting Bar was scientifically formulated with these ingredients so that it doesn’t trigger the food sensing system, unlike your usual meals. We call this the fasting mimicking effect and it means that when you eat it during your fasting window, it curbs your hunger without breaking your fast, so you can fast for longer*!

How to enjoy a Fast Bar® and experience the health benefits that come with it

Why and when to use a Fasting Bar

  • Fasting Bar is ideal for those who skip breakfast, practice intermittent fasting, or follow a paleo, keto or fasting diet;
  • Give your body heart-healthy nuts;
  • Enjoy one as a snack anytime during the day to fuel your body when on the go;
  • Fasting bars can be purchased in boxes of 12.

Fasting Bar’s recipe is designed to nourish your body while maintaining its fasting state. For that reason, it’s best enjoyed during either your morning intermittent fasting window or as a late-night snack to satiate you before bed.

Similar to water, our delicious flavours do not raise your blood glucose levels and keep your ketones in a fasting state!

Frequently Asked Questions Fasting Bar

ProLon® Nutrition Bar is an intermittent fasting bar that can help curb your hunger without breaking your fast, so you can fast for longer. It has been clinically shown to keep your body in a fasting state even after eating. You can eat it in the morning after your overnight fast to help curb your hunger and extend your fast until your next meal. A clinical trial showed that eating a Fast Bar after an overnight fast has a similar impact on ketones and a nearly identical impact on blood glucose as drinking water*.

 

* Benefits seen in a randomized, controlled study in 105 adults after a 15-hour overnight fast comparing the glucose and ketone results every hour for 4 hours in the Nutrition Bar group, breakfast group and water-fast group. Data on file.

You should eat Nutrition Bar once a day, as we want people to follow a healthy, balanced diet including regular meals during the day.

You can eat it in the morning after your overnight fast or as a healthy snack anytime during the day, in addition to meals, to help curb your hunger.

The impact and safety of consuming more than one Nutrition Bar per day hasn’t been studied, and we recommend that you eat only one Fast Bar in the morning or evening, along with a healthy, balanced diet for your other meals.

Fast Bar is great for supporting Time Restricted Eating and other short fasts. If you seek the benefits of Prolonged Periodic Fasting, our 5-Day ProLon Fasting Mimicking Diet (FMD) has been extensively tested, has been safely used by hundreds of thousands of generally healthy consumers, and has been clinically tested to provide many benefits, and support overall metabolic health when used in multiple consecutive cycles.

The Nutrition Bar study tested the effects of eating a Nutrition Bar at breakfast time (after a 15-hour overnight fast), compared to either skipping breakfast or eating a standardized breakfast bar. The study looked at blood glucose and ketone levels over the 4-hour period after breakfast time and showed that blood glucose levels in patients eating Nutrition Bar were nearly identical to blood glucose levels in patients who skipped breakfast.

Ketone levels over the 4 hours were also very similar in both groups. These results showed that eating a Nutrition Bar doesn’t interfere with key physiological markers of fasting. The study also showed that Nutrition Bar gave people a feeling of being fuller and curbed the desire to eat for up to 3 hours after consumption. In other words, you can eat a Nutrition Bar to help make fasting easier and more pleasant, and maintain similar ketone and blood glucose levels as a water-only fast.

Yes! Nutrition Bar is designed with the same technology as the ProLon Fasting Mimicking Diet®. Our technology is the result of over 20 years of preclinical and clinical testing with over 36 million US dollars in research and development funding from the National Institutes of Health and the European Union.

Scientists used to think that calorie balance (i.e.: calories consumed minus calories burned) was the most important factor in weight loss. But scientists now widely accept that not all calories are the same. Factors such as macronutrient ratios, total amounts, how the nutrients are digested and absorbed, and molecular composition all have an impact on how the body processes food.

The Fasting Mimicking Diet (FMD) and Nutrition Bar have been carefully engineered, extensively researched, and clinically tested to allow for the consumption of nutrients and calories but still keep cells in a fasting state. Our special patented formula effectively hides from the body’s nutrient sensors, preventing them from sending the hormone signal that typically is sent after eating. The cells respond to the decrease in this hormone signal by entering a fasting state.

Nutrition Bar was designed with the same technology as ProLon’s L-Bars, but there are slight differences in size, calorie count and overall sugar content. Due to the carefully formulated macro and micro-nutrient ratios of the individual bars, they’re not intended to be interchangeable and should only be used as directed.
