Why you'll love fasting with food

Cellular Rejuvenation (Autophagy)

A fasting induced miracle of biology called autophagy (which won the Nobel Prize in Medicine in 20), cellular rejuvenation is key to your vibrance, emotions, performance, mental clarity,healthy aging and longevity.

Fat Focused
Weight Loss

Kickstart weight loss (on average 5 pounds), especially belly fat, while protecting lean body mass, (which althletes and performance minded will love). The key is your body thinks you're fasting, while you're staying nourished.

Changed Relationship
with Food

In this 5-day journey, ProLon helps you to understand, appreciate, and change your relationship with food. You can successfully function without all the mindless eating and extra calories.

Improved Sense
of Well-being

Your emotional well being is a huge benefit as most people after ProLon feel successful vs the other long term diets that set you up to quit. Feel empowered, rejuvenated, vibrant, and with more mental clarity.

Healthier, Younger
Looking Skin

Clinically shown after 3 cycles of ProLon (15 days total), to reduce fine lines and wrinkles. Your skin is rejuvenating from the insdie out, which users come to love!

Convenient, Fits Into Every Lifestyle

The beauty of ProLon Fasting Nutrition is it is in 5-day cycles. We recommend doing at least 3 cycles a year (only 15 days). You can include ProLon into your already healthy routine with minimal disruption.

Get the benefits of fasting without getting exhausted...

Get the benefits of fasting without getting exhausted and burning off all the muscle. I resumed heavy weight lifting right after the fast. This really is a breakthrough.

I can’t recommend ProLon enough...

I discovered ProLon last January and I have been doing it consistently ever since then. It is a really great reset for your body, especially after holidays. It has so many different benefits, it curbs sugar cravings and helps me manage portion control.

I'm 50 years old with 2 small children...

I started ProLon and I'm telling you, it worked! I lost 6 pounds, I have no brain fog, I absolutely do not crave sugar right now which is insane and I actually feel amazing, I'm full of energy! I am so proud of myself, my husband did it with me, he lost 5 pounds, says he has never felt better.

This is my third time trying the fast mimicking diet, and I have learned to go back to it whenever I need a reset. I tend to do great at watching what I eat for a period of time, but then start slipping back into old habits over time. At that point, I find that if I do the fast mimicking diet again, it really does reset my thinking about how much I need to eat.
