ProLon is not intended to diagnose, treat, cure, or prevent any disease and these statements have not been evaluated by the FDA.

What is ProLon?

ProLon is a 5-day meal program that is based on 20 years and $36 Million in research and development. Prolon supports intermittent fasting goals by providing food that maximizes nourishment without triggering the body’s food sensing system! It has helped thousands of people to jumpstart their healthy lifestyle goals.

I did ProLon for the first time back in March 2021 and I’m ready to get after again this June. Was it easy? Hell no! But the results were worth it and I’m ready to get after it again!

ProLon is unlike any other diet program (and I’ve tried all of them). The specially designed food gives you essential nutrition but doesn’t activate your body’s food sensing system.

In other words, you get to eat, but your body “thinks” it’s on a 5-day fast.

Essentially, it’s a “fast with food.” If that sounds easier than fasting by starvation, that’s because it is.

What makes ProLon so special is, simply put, the science. It’s based on over 20 years of scientific research sponsored by the National Institutes of Health and the USC Longevity Institute.

How was the ProLon Fast Mimicking Diet discovered?

ProLon is the only clinically-tested, doctor-recommended fasting meal program. Dr. Longo’s breakthrough nutri-technology was researched and developed for over 20 years at The Longevity Institute at the University of Southern California. ProLon works by unlocking the deepest level of fasting and triggering “autophagy.” This is the natural way our cells clean damaged intracellular components out and gets rid of intracellular debris, resulting in cellular rejuvenation throughout the entire body.

What are the benefits of the ProLon Fast Mimicking Diet?

Results can vary from person to person, as each body is different, but ProLon can bring about healthy changes, both inside and out. The main benefits of ProLon are:

  • Weight Loss and Loss of Belly Fat
  • Enhanced Performance – improved mental clarity, focus, and energy

  • Formation of Healthy Habits – healthier relationship with food, reduced food cravings, and improved portion control

  • Healthy Aging – through cellular rejuvenation when ProLon is used in multiple consecutive monthly cycles

When you sign up, what does the ProLon Fast Mimicking Diet include?

This 5-day diet features 5 small boxes, one for each day, packed with everything you’ll eat during that time. ProLon’s food is plant-based and contains the right amount of macro and micronutrients you need while still mimicking the fasting state.

The meal program includes a nut bar for breakfast, a plant-based soup for lunch, and a second plant-based soup for dinner. There are snacks throughout the day, such as olives and kale crackers. Some nights there’s even a Choco Crisp bar. You also get herbal tea bags, supplements, and an energy drink that you add to water on days 2 through 5. You can add herbs to the soups in small quantities, to taste if you’d like, and of course, coffee is allowed (up to 8 oz per day, with nothing added). Everything is designed by a Michelin Star chef, too.

What does the 5-day program look like?

Day 1 – Your body transforms to fasting and fat-burning state

Day 2 – Fat-burning ramps up and ketogenesis usually begins on this day

Day 3 – Autophagy and clean-up stage, ketogenesis continues

Day 4 – Cellular Rejuvenation, ketogenesis continues

Day 5 – Cellular Renewal and ketogenesis continues past day 5

How quickly can you expect results?

The first 5-day fast can cause many users to feel benefits like more energy, weight loss, and fewer cravings. To gain the full advantages of ProLon, fasters are advised to do the Fasting Mimicking Diet for 5 consecutive days once a month for 3 consecutive months to match what was done in clinical studies where the benefits were first identified.

Prolon Review, What's in the kit

My Dos and Don’ts


Do it with a friend

I did it with my virtual homie and it really helped! You need someone to complain to. TRUST ME! If you signup with my link and code you are welcome to join our Facebook group. Just email me at to join.

Do it Monday – Friday

Trust me when I tell you that you don’t want to be ProLon over the weekend. If your schedule allows it doing it during the workweek makes it SO much easier!

And if you’re doing it Monday – Friday avoid Sunday Funday like the plague! ProLon and hangovers don’t do well together.

Do season it

You can add up to one teaspoon of combined salt, herbs, and spices to the soups each day.

Check out this post with the best ways to season each soup.

Do water it down

In addition to adding seasoning to the soup, I also added more than the suggested water to the soup. I felt fuller and less HANGRY!

Do be prepared to use the restroom…a lot!

Stay close to home. TRUST ME!

Do go to bed early

Short days = less hanger.

Do get vaccinated, but don’t do it the first day of the fast

The WORST idea I EVER had!


Don’t Cheat

I did (a little) and it wasn’t worth it.

Don’t give up your morning coffee.

I skipped my morning coffee on Day 1 and it was an epic mistake. Drink the coffee and avoid any cream or sugar.

Don’t hit the gym hard.

Skip Barry’s your ProLon week (your bank account will thank you).  Do go for a walk or do a light stretch, just don’t overdo it. It isn’t worth it!
