Why do a fasting mimicking diet?

Fasting has long been used as a means of promoting weight loss and reducing the burden of digestion so that the body can enter into a state of repair and rejuvenation. However, fasting for extended periods of time is not without risk, and restrictive water or juice fasts are difficult to maintain.

The fasting mimicking diet allows the body to enter into a fasting state while still providing nourishment. The delicious foods and resulting feelings of satiety make it easy to stay on the diet for the intended 5-day period and experience all of the benefits of short-term fasting.

What do you eat on the fasting mimicking diet?

Everything you need for your 5-day fasting mimicking diet is included in your ProLon kit. You’ll receive 5 boxes — one for each day — that include great-tasting, plant-based energy bars, soups, snacks, drinks, and energy-building supplements, all scientifically tested and designed to nourish your body while promoting positive changes related to metabolic markers, inflammation, cellular rejuvenation, and healthy aging.

ProLon was created in collaboration with some of the world’s best food scientists and chefs to provide great-tasting foods that make the diet easy to follow. The convenient, day-by-day packaging removes any guesswork and results in minimal disruption to your daily lifestyle.

During the 5 days that you follow the ProLon diet, you will not consume any other foods or beverages other than water.

ProLon foods use plant-based ingredients and do not contain any additive or chemicals. ProLon uses healthy ingredients such as fresh olives, vegetables, fruit, nuts, seeds, dark chocolate, and herbal teas.

The daily caloric intake with the ProLon diet is between 770 and 1100 daily calories from healthy foods that are carefully designed to nourish your body and promote positive changes.

Because the ProLon diet is low in calories, hunger may occur during the 5-day diet period. Most clinical trial participants experienced only low levels of periodic hunger and reported that the hunger subsided by the third or fourth day.

Because coffee can interfere with the beneficial effects of the diet, it is not recommended while using ProLon. However, if you feel that you must have coffee, we recommend minimizing your consumption to one cup per day.

ProLon is the results of 15 years of extensive preclinical and clinical studies sponsored by the National Institute of Health (NIH) and conducted at the Longevity Institute and Diabetes and Obesity Research Institute of the University of Southern California (USC). These studies found that ProLon stimulates cellular entry into a high protection and stress-resistant mode, removal of damaged cells and tissues, and self-repair through cellular regeneration and rejuvenation.
