Prolon Fasting Benefits Close Open

Prolon, essential to vibrant life!

Everyday we stress and intoxicate our body and mind with our current lifestyle, nutrition, environment we live under. As we age, our cellular capability to detox, recover and heal decrease and older senescent cells outnumber young vibrant cells.

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.

The Science of Prolon Close Open

Backed by & continually advancing through science.

After two decades and tens of millions in Research & Development, L-Nutra (a leading Nutri-tech company) and The University of Southern California, led by Dr. Valter Longo were able to identify cellular radars that detect nutrition, called Nutrient Sensing Pathways, and to develop a 5 day Nutrition Program that nourishes the body while the food sensing pathways are not triggered and therefore providing the prolonged fasting benefits.

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.

FAQs Close Open

How should the Prolon program be used?

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).

What are the food pathways affected by Prolon?

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.

What happens to my body during the fasting mimicking program?

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.

How much weight am I expect to lose?

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.

What is the daily caloric intake during Prolon?

Day 1 has about 1100 calories (kcals), while Days 2-5 have between 700 and 800 calories (kcals) per day.
