Why to add fast bar to your day?
Fast bar secret ingredients
The secretive fast bar formulation is the fruit of two decades of collaboration between Nature and our Scientists who unlocked a natural nutri-technology of fasting with food or fasting mimicking diet. Recently, 14 global universities joined the research and helped us bring to the world the Fast Bar, Fasting Shake, Reset, and ProLon Five Days Fasting Nutirition.
Yes — Amazingly, when you eat Fast Bar, your body thinks it's still fasting
Fasting Bar’s proprietary formula of premium ingredients doesn’t trigger your body’s nutrient sensing system, so your body’s tricked into thinking it’s fasting.
Fasting Bar’s recipe comes from more than 20 years of research at the University of Southern California (USC). Scientists studied how unique blends of macronutrients and micronutrients could be consumed without kicking your body out of a fasting state.
Delicious + Healthy = Extraodinary
Fasting Bar is made with premium nuts like Macadamias. Nuts contain a variety of health-supporting nutrients like antioxidants, vitamins, minerals, fiber and Omega-3 fatty acids.
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 flavors do not raise your blood glucose levels and keep your ketones in a fasting state*!
Frequently Asked Questions?
Fast 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 Fast Bar group, breakfast group and water-fast group. Data on file.
You should eat Fast 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 Fast 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 Fast Bar study tested the effects of eating a Fast 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 Fast 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 Fast Bar doesn’t interfere with key physiological markers of fasting. The study also showed that Fast 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 Fast Bar to help make fasting easier and more pleasant, and maintain similar ketone and blood glucose levels as a water-only fast.
Yes! Fast 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 Fast 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.
Fast 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.
Prolon was designed and clinically tested by 18 global universities to nourish your body while inducing the cellular, metabolic, and emotional benefits of prolonged fasting. In three 5-day cycles of ProLon, you can fuel your body into rejuvenation, longevity, and healthy living.
- Metabolic health
- Cellular Rejuvenation
- Fat-focused weight loss
- Changed relationship with food
- Best results & successful transformations

Prolon, essential to vibrant life!
Our ancestors had a natural secret to defend against accelerated aging and to rejuvenate younger cells: proLonged fasting (> 3 days). When fasting, the body uses its reserves (fat and glycogen) for the first 2 days (Intermittent Fasting period) but when fasting crosses 3 days or more (the prolonged fasting period), the body undergoes a next level of ‘protective and rejuvenative defense called autophagy.
In modern days, we accelerate cellular damage and aging vs going into periods of autophagy, recovery and rejuvenation.In 5 short days ProLon allows your body to go into a rejuvenating state, while consuming macro and micro nutrients to keep your body nourished.

Backed by & continually advancing through science.
Prolon provides the body with healthy, plant-based ingredients that have been scientifically demonstrated to provide the body with optimal nourishment while not activating the key pro-aging pathways, or food sensing pathways — pathways which are activated by normal diets.

The amazing part about ProLon is it can easily fit into your lifestylle and is only a 5 day change to your normal life.
Suggested consumption by Dr. Valter Longo, head of the Longevity Institute at University of Southern California and Author of the Longevity Diet.
• If you have a health or metabolic objective in mind and want to achieve faster the metabolic and rejuvenative successes of ProLon, then you can do ProLon every month for 3 or 4 months and then do it once every 3 months to maintain the benefits.
• 2 times only per year for Healthy Aging (10 days out of 365 days!)
• 3 times per year for Healthy Aging and added Weight Loss (15 days out of 365 days!)
Some people do ProLon once a month for reasons that are in line with therapeutic effects of fasting that we are also researching and will launch under a dietitian guided program in 2023.
The diet should be used for five consecutive days, after which the individual will transition on the 6th day and then resume their normal diet. The program provides a meal card that recommends how to consume the items for each day, but each day’s items can be consumed in any order you wish, as long as you only eat each day’s items during that day (do not carry them over to the next).
While there are many different signaling factors in the “nutrient-sensing pathways” involved with cellular fasting, the 3 primary nutrient-sensing pathways that ProLon and fasting down-regulate are IGF-1, mTOR, and PKA. The process is complex, and each pathway can interact with other pathways, but in general, PKA responds primarily to sugar and carbohydrates, while IGF-1 is primarily responsive to protein (and more strongly triggered by animal protein), and mTOR is triggered by IGF-1 and amino acids. Sugar and carbohydrates (and to some extent caffeine) will activate PKA. These nutrient-sensing pathways all help regulate the cells’ growth cycles and stress-resistant “fasting” state.
ProLon provides the body with a scientifically developed, naturally occurring combination of macronutrients (fats, carbohydrates, proteins) and micronutrients (essential vitamins and minerals) designed to keep the body nourished while going through the rejuvenating process of the fasting state.
WHAT HAPPENS ON DAYS 1 TO 5 ON MY PROLON FAST?
Day 1: Transforming to a Fasting State: Your body is transitioning to a fasting state and fat- burning mode, and begins preparation for cellular clean-up.
Day 2: Fat Burning & Ketogenesis: Fast Burning & Ketogenesis: Fat-Burning ramps up, contributing to the initiation of ketogenesis (ketone production). By the end of this day (48 hours), ketosis may occur.
Day 3: Autophagy Clean Up State: Cellular clean-up (autophagy) Fat-burning and ketone production/utilization continues and increases.
Day 4: Cellular Rejuvenation:Cellular cleaning/renewal & fat-burning You’re in the final stretch.
Day 5: Renewal & Change: Fast completed, cellular renewal continues beyond Day 5.
While the purpose of the ProLon diet is to trigger rejuvenation, weight loss may occur. Everyone is different, and weight loss depends on a number of factors. In a clinical study of participants who completed a 5-day ProLon cycle once a month for three months, the average weight loss at the end of the study was about 5.7 pounds. This was primarily abdominal fat, while lean body mass was preserved.
Day 1 has about 1100 calories (kcals), while Days 2-5 have between 700 and 800 calories (kcals) per day.

What is it & how is it used?
ProLon ReSet is a 1-day fasting nutrition program that uses a patented, precise blend of plant-based nutrients to provide you essential nutrition and fuel without activating your body’s food sensing system. ProLon ReSet is for people who are interested in amping up their Intermittent Fasting, or simply giving their body a much-needed break from mindless eating and high-calorie sugar and carb diets with a nutrition program that can give you the benefits of a full day fast.
In short, ProLon ReSet introduces you to the world of fasting by giving your body a break and chance to ReSet. ProLon ReSet can help manage your hunger with this 1 day fasting kit and experience a full day fast without starving yourself.
How does ProLon ReSet support fasting?
ProLon ReSet helps you enter the transformational fasting lifestyle of fasting with food*. When you do a ProLon ReSet, you eat while your body thinks it’s fasting because the scientifically designed combination of nutrients does not trigger nutrient sensing pathways. During this 1-day fast, your body’s ketone levels will rise as your body starts to break down fat stores for fuel, and your glucose levels will remain steady – similar to what happens when you’re fasting.
*Based on the fasting mimicking technology of ProLon.
ProLon ReSet is for people who are interested in amping up their Intermittent Fasting, or simply giving their body a much-needed break from mindless eating and high-calorie sugar and carb diets with a nutrition program that can give you the benefits of a full day fast. This reset is for you if you want to:
• Give your body a 1-day break from mindless eating and a high-calorie sugar and carb diet and allow the body to recover through active fasting.
• Break the cycle and balance out over-indulgence with a 1-day ReSet intervention
• Amp up your cleanse and Intermittent Fasting routines
• Start your journey into healthy aging through an Intermittent Fasting Longevity lifestyle
*If you have diabetes or are taking any medication that affects blood sugar please consult with a healthcare provider prior to attempting fasting or a low-calorie diet. Consult with a healthcare professional before starting any diet, supplement or exercise program.
ProLon ReSet makes it easier to fast for a full day by giving you nourishment, fuel, and curbing hunger while keeping your body fasting!
- Use as a full day fasting break for your body whenever you need a reset from unhealthy eating
- Use to amp up your cleanse routine. You can choose to use it twice per week to optimize the benefits of the reset.
-
Use as part of your Intermittent Fasting (5:2 Diet) routine.
- Intermittent fasting (IF) can be defined as fasting for less than 2 days and has become the number one diet in the United States. While there are a variety of fasting methods within the category of IF, such as the 5:2 Diet, they are all based on eating patterns that alternate between intervals of eating and fasting.
- ProLon ReSet is ideal to use within the 5:2 Diet: this type of IF entails fasting during specific days of the week. For this approach, individuals either eliminate or severely restrict their calories for two (non-consecutive) days of the week and then resume their normal diet for the other five days. You can use ProLon ReSet on your 2 fasting days per week and eat your regular diet for the other 5 days of the week.
With ProLon ReSet, you can experience a 1-day fast to see if fasting is right for you or use it whenever you feel you need a reset from overindulgence. You can use ProLon ReSet to either:
- Amp up your cleanse routine by using it twice per week to optimize the benefits of the reset.
- Incorporate into your intermittent fasting 5:2 Diet routine. Consistent with the duration of your 5:2 Diet routine, you can use ProLon ReSet on your 2 fasting days per week and eat your regular diet for the other 5 days of the week. For example, if you choose to follow a 5:2 routine for 3 weeks every month, you would use 6 resets within that month.
If you seek the benefits of Prolonged Fasting including autophagy and rejuvenation, 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 including the support overall metabolic health when used in multiple consecutive cycles. As with any diet, you should talk to your healthcare provider, who may recommend doing monthly cycles until you reach your individual goals, and then every 3-6 months thereafter to maintain benefits.
ProLon ReSet 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, inspired by Nobel Prize winning science and awarded over 36 million US dollars in research and development funding from institutions including the National Institutes of Health and the European Union.
Although additions are discouraged to minimize the risk of breaking the fast, you can choose to add:
• Unlimited herbal teas (unsweetened and caffeine free)
• All types of sparkling water are fine (no sweeteners of any kind)
• Caffeine up to 140 mg per day:
--1 cup (8-12fl oz) of coffee (no cream or sweetener)
---or- 2 cups (16fl oz) of black or green tea (traditionally steeped), no matcha
---or- 6 cups (48fl oz) of decaf coffee (no cream of sweetener)
• Up to 1 tablespoon of dried herbs or spices per day to your soups or other foods in the diet to enhance the flavor (preferably unprocessed, e.g., red pepper flakes)
• Up to 1 teaspoon of sea salt (as long as there are no health contraindications)
• Up to 2 slices of lemon per day (squeezed, not eaten), whether you use it in your soups, herbal teas, or water.
• Up to 2 pieces of sugar-free gum per day while on ProLon.
You should add food to the program only as a last resort if you are so incredibly hungry that you feel like you are going to break the fast. In such an instance, you may have a slice or two of apple, 1 stalk of celery, or 1 small Persian (“baby”) cucumber of 5-6 inches in length per day.
ProLon ReSet is designed to support intermittent fasting (overnight fasts, and fasts lasting less than two days) as part of an everyday healthy lifestyle. If you’re looking for the benefits of prolonged periodic fasting (longer than 2 days) including support of weight loss and fat loss, metabolic health, or a jumpstart to lifestyle transformation, we recommend that you try the 5-Day ProLon Fasting Mimicking Diet.
ProLon ReSet is a 1-day fast that is derived from the science behind the 5-day ProLon Fasting Mimicking Diet. ProLon ReSet is designed to support intermittent fasting (overnight fasts, and fasts lasting less than two days) as part of an everyday healthy lifestyle.
If you’re looking for the benefits of prolonged periodic fasting (PF) (longer than 2 days), including support of weight loss and fat loss, cellular rejuvenation, metabolic health, or a jumpstart to lifestyle transformation, we recommend that you try the 5-Day ProLon Fasting Mimicking Diet. Due to its extended duration, PF goes beyond providing weight loss and fat reduction to promote biological fasting and a process known as autophagy, the clean-up of aging and worn-out intracellular components. These cellular cleansing and rejuvenating effects can only be attained through cellular stress such as a prolonged fast like the 5-day ProLon FMD.
ProLon ReSet is designed to use as a full day fasting break when you need a reset, want to amp up your cleansing routine, or are practicing intermittent fasting as part of a 5:2 Diet routine (fast 2 days per week, eat regular diet for other 5 days of the week). We do not recommend adding a ProLon ReSet day before or after completing 5 days of ProLon, as this has not been tested in any of our studies and may be unsafe in certain people.
Prolon Reset is our newest version of a 1-day fast with ProLon. While ProLon Fast Pack offered a way to ease yourself into fasting, ProLon ReSet offers a 1-day fast that has been shown to keep your body in a fasted state*. This newer formulation along with fewer calories, is derived from the science behind the 5-day ProLon Fasting Mimicking Diet and is specifically designed to support intermittent fasting (IF) routines. We have designed ProLon ReSet to fit a 5:2 Diet which is an intermittent fasting diet that allows people to eat their regular diet 5 days a week and then limit calories on the other 2 (non-consecutive) days. You can use ProLon ReSet on your fasting days for IF up to a day or as part of your 5:2 diet routine, depending on your needs and lifestyle.
