The Five-Day Fasting Mimicking Diet: My Brutal Review of Prolon
Prolon: The Five-Day Fasting Mimicking Diet
If you’ve been following my journey for a while, you know that my relationship with my body has been a bit of a rollercoaster. For years, I’ve dealt with the frustrating, often unpredictable symptoms of Irritable Bowel Syndrome (IBS). On top of that, having navigated past liver issues, I am hyper-aware of how my internal organs are functioning. I often feel sluggish, bloated, and just "heavy" in my own skin.
I was desperately looking for a way to hit the ultimate "reset" button. I didn’t just want a juice cleanse that would spike my blood sugar or a water fast that would leave me fainted on the floor. I wanted a scientific, structured way to target inflammation and give my gut a chance to heal from the inside out.
That’s what led me to ProLon, the Five-Day Fasting Mimicking Diet (FMD). After completing my first five days, I can honestly say the results were better than I ever imagined. Here is my brutally honest breakdown of the experience.
How the ProLon Cleanse Actually Works: Science in a Box
Before we get into the "brutal" part of the review, let's talk about what this actually is. How do you "eat" while your body thinks it’s fasting? ProLon is a meticulously designed nutrition program backed by over 20 years of clinical research at the University of Southern California (USC). It was developed by Dr. Valter Longo, a world-renowned leader in longevity.
When your kit arrives, you receive five individual boxes—one for each day. Inside, everything is pre-portioned and labeled. There is zero guesswork. You aren't scanning barcodes or counting calories; the scientists have already done that for you.
What do you eat? The menu is entirely plant-based and surprisingly gourmet. You’ll find:
Soups: Varieties like tomato, mushroom, minestrone, and butternut squash.
Nut Bars: The "L-Bar" is a fan favorite—it's a dense, nutty bar made with macadamias, pecans, and honey.
Snacks: Savory kale crackers and sea-salt olives (which become your best friend by Day 3).
Supplements & Drinks: You get a daily multivitamin, algal oil (Omega-3), hibiscus tea, and a special "L-Drink"—a glycerol-based energy drink you sip throughout the day to protect your muscle mass while you burn fat.
The Magic of the "Mimic": You eat about three times a day (breakfast, lunch, and dinner) with snacks interspersed. The secret is the specific macronutrient ratio. The food is formulated to provide enough nourishment to keep you functional, but it is low enough in protein and carbohydrates that your nutrient-sensing pathways (like mTOR and PKA) aren't triggered. Your cells don't "register" that food is entering the system. This keeps your body in a state of autophagy—a fancy word for "self-eating"—where your body starts breaking down old, damaged cellular components and regenerating new, healthy ones.
1. Why I Committed: The Quest for a Total Gut Reset
My primary motivation was my gut. Living with IBS means your digestive tract is often in a state of hyper-sensitivity. I constantly felt like I was reacting to everything I ate, no matter how "clean" it was. I knew that my liver, given its history, could also use a break from the constant task of processing modern toxins and heavy meals.
I wanted to see if five days of precision nutrition could undo months of digestive discomfort. The Fasting Mimicking Diet isn't just about weight; it's about cellular renewal. By giving the digestive system a "break" from heavy lifting, the body can redirect that energy toward repairing the gut lining and reducing systemic inflammation. For me, this wasn't about a fad; it was about a medical-grade intervention for my long-term health.
2. The Physical Transformation: Losing Weight and Gaining a Glow
Let’s talk about the results everyone wants to hear about. By the morning of Day 6, I stepped on the scale and realized I had lost five pounds. While some of that is certainly water weight and reduced bloating, I felt a genuine change in my body composition. My clothes fit differently—especially around my midsection, where IBS bloating usually makes things tight and uncomfortable.
But the most unexpected and delightful side effect was my skin. About halfway through Day 4, I looked in the mirror and realized my skin genuinely GLOWED. I’m talking about that lit-from-within radiance that no expensive serum can replicate. My complexion was clear, the dark circles under my eyes had faded, and the overall texture of my skin felt incredibly smooth. It’s like a facial for your entire internal system. If you have an event coming up or just feel like your skin has lost its luster, the "ProLon Glow" is a very real phenomenon.
3. The Mental Journey: From Hunger Pangs to High Performance
I promised a "brutal" review, so here it is: The first three days require focus. On Day 1, you get the most calories, so it feels like a breeze. But on Day 2 and Day 3, the calories drop, and your body starts searching for its usual fuel sources. I definitely felt the hunger. I had moments where I missed the act of "social eating" and felt a bit of a "fasting flu" (a slight headache as my body switched from burning glucose to burning fat).
However, something miraculous happened on Day 4. It was like a switch flipped in my brain. The hunger vanished almost entirely. I woke up with immense energy and mental clarity. I didn't need my usual morning coffee to feel human; I was alert, sharp, and incredibly productive.
This is the state of "ketosis" and "autophagy" working together. When your brain starts fueled by ketones, the "brain fog" associated with IBS and poor digestion lifts. I felt lighter and more vibrant than I had in months. It’s a unique kind of "fasting fuel"—you aren't running on a sugar high; you’re running on a deep, stable reservoir of energy.
4. Why I’m Making This a Monthly Ritual
One round of ProLon was life-changing, but I’ve decided I’m not stopping there. The clinical studies show that the most profound benefits—especially for metabolic health and inflammatory markers—occur when you do three consecutive cycles (one five-day box per month for three months).
Because I want to stay on top of my IBS and keep my liver health a priority, I’ve decided to commit to a monthly cleanse. Doing this once a month serves as a "maintenance" program for my gut. It prevents the slow creep of inflammation and ensures that I’m regularly triggering that cellular clean-up. It’s much easier to stay disciplined in my daily life when I know I have a structured "reset" scheduled every 30 days to keep me on track.
5. Join My January Journey: Your Turn for a Reset
I’m already counting down the days until my second cleanse in January. There is something so empowering about starting the new year by giving your body exactly what it needs to thrive. I’m going to be documenting the whole process—the soups, the energy levels, and the "Day 5" results—on my social media.
If you’ve been struggling with bloating, brain fog, or skin issues, or if you just want to see what your body is truly capable of when it's not bogged down by digestion, I want you to do this with me! Let’s support each other through those first three days and celebrate the Day 4 energy surge together.
