ProLon is a 5-day Fasting Mimicking Diet that lets your body experience the benefits of fasting—like fat loss and cellular renewal—while you still eat. Kaufman Health and Hormone Center is offering the program for $125 (originally $172), making it an ideal summer reset before or after vacation, or alongside GLP-1 therapy.
Summer has a way of inspiring us to take better care of ourselves. Maybe you’re prepping for a beach trip. Maybe you just got back from one and you’re ready to feel like yourself again. Either way, you deserve a thoughtful, science-backed way to support your body—not another crash diet that leaves you depleted.
That’s where ProLon comes in. For a limited time, the ProLon 5-Day Fasting Mimicking Program is available at Kaufman Health and Hormone Center for just $125 (originally $172). It’s a simple, guided way to give your metabolism a fresh start while still eating real food every day.
Here, we’ll explore what ProLon is, the science behind it, who it’s best suited for, and how to claim the sale price. Our goal is to help you decide whether a five-day reset is the right next step for you.
What is the ProLon Fasting Mimicking Diet?
ProLon is a 5-day Fasting Mimicking Diet (FMD)—a prepackaged program designed to give your body the benefits of fasting while you keep eating. Each day, you enjoy plant-based soups, energy bars, snacks, herbal teas, and supplements, all carefully portioned and delivered in one box.
The program was developed by Dr. Valter Longo at the University of Southern California and is built on more than two decades of research. The science is clever: the meals provide just enough nutrients to nourish your body, while keeping calories low enough that your cells believe you’re fasting. You get the cellular benefits of going without food—without the difficulty of a water-only fast.
Why does ProLon work? The science of autophagy and cellular renewal
When your body enters a fasting state, it begins a natural cleanup process called autophagy. During autophagy, your cells clear out damaged components and regenerate—a process closely tied to healthy aging and disease prevention.
ProLon is designed to trigger this process while protecting what matters most. Here’s what the research shows it can do:
- Target visceral fat. ProLon helps your body burn stubborn belly fat, the type linked to heart disease, diabetes, and liver problems.
- Protect lean muscle. Unlike extreme diets, ProLon is clinically formulated to preserve the muscle that drives your metabolism.
- Reset your metabolism. The program helps shift your body into a fat-burning state and supports healthy metabolic markers.
- Reduce inflammation. Studies show fasting-mimicking cycles can lower systemic inflammation markers like CRP and IL-6.
In one five-day cycle, many people lose up to five pounds or more. Over three consecutive monthly cycles, research points to a reduction in waist circumference of about 1.5 inches—and studies suggest the weight loss tends to stay off even after returning to a normal diet.
The American Diabetes Association has also recognized the ProLon protocol as a promising clinical tool for metabolic health, a meaningful endorsement from one of the most respected institutions in medicine.
Who is ProLon best for?
ProLon is designed for healthy adults who want to optimize their well-being, as well as those working toward weight and metabolic goals. It’s a wonderful fit if you’re:
- Prepping for vacation and want to feel confident and energized before you travel.
- Coming home from vacation and ready to gently reset after a few weeks of indulgence.
- Using GLP-1 therapy and looking to protect your muscle while you lose weight (more on that below).
- Seeking a jumpstart to healthier habits and a more mindful relationship with food.
A quick note: ProLon isn’t right for everyone. It’s not recommended during pregnancy or breastfeeding, for those under 18 or over 70, or for anyone with certain health conditions. If you have diabetes, a heart condition, or another concern, our team can help you decide whether ProLon is a safe choice for you.
Can you combine ProLon with GLP-1 therapy?
Yes—and it’s one of the most thoughtful pairings in metabolic health today. GLP-1 medications like Ozempic and Wegovy can deliver real weight loss results, but they come with a tradeoff: up to 40% of the weight lost on GLP-1s can be lean muscle rather than fat. Losing muscle can slow your metabolism and make weight regain easier.
ProLon works differently. Because it’s formulated to protect lean tissue while targeting fat, it can complement your GLP-1 journey beautifully. You get the fat-burning support you’re after, with care taken to preserve the muscle that keeps your metabolism strong. If you’re already on a GLP-1 and want to make the most of your progress, ProLon may be the missing piece.
What should you expect during your 5 days?
Knowing what’s ahead makes the experience much easier. Here’s a simple breakdown of how the five days unfold:
- Day 1: Your body begins transitioning into a fasting state.
- Days 2–3: Fat-burning and ketogenesis kick in.
- Days 4–5: Cellular cleanup (autophagy) and regeneration are most active.
Each day comes with everything you need, so there’s no guesswork and no grocery shopping. Some people notice mild fatigue, headaches, or trouble concentrating, especially in the first couple of days—this is normal as your body adjusts. It’s best to keep activity light and avoid extreme heat, like saunas and hot tubs, during the program. Many people finish the five days reporting better portion control and a more mindful approach to eating.
One patient’s experience:
What was each day actually like?
I want to be real about this, because I went in skeptical. Here’s the honest version.
Day 1 was easier than I expected. The bars were genuinely tasty, the soups were comforting, and I kept busy. I felt a little hungry by evening, but nothing dramatic.
Day 2 was the hard one. My brain kept whispering about snacks—what I’ve since learned is called “food noise.” I leaned on sparkling water and the hibiscus tea, and I texted my husband for moral support more than once.
Day 3 was the turning point. I woke up bracing for misery, and instead I felt steady. My energy returned in the afternoon, almost like a switch flipped. My body was finally getting the hint.
By Days 4 and 5, I felt genuinely good. My head was clear in a way I hadn’t felt in months. I’d sit down to work and just focus—no 3 p.m. crash, no reaching for coffee. A couple of times I forgot it was even mealtime.
The team at Kaufman walked me through what to expect before I started, which made all the difference. Knowing the foggy moments on Day 2 were normal kept me from quitting.
