If you’ve struggled to get your weight or health on track, tried wellness protocols that didn’t work, or simply want a reset and results that stick, this program is designed for you.
It’s especially effective if you’re dealing with:
Weight challenges—if you’re overweight or want sustainable fat loss while protecting muscle.
Metabolic imbalance—if markers like LDL cholesterol, triglycerides, blood pressure, or insulin resistance are outside the ideal range.
Cardiometabolic conditions— if you’re dealing with challenges such as hypertension, high cholesterol, hyperlipidemia, prediabetes, or inflammation.
Medication reliance—if you’re currently using medications for blood pressure, cholesterol, or weight loss (including GLP-1s) and want to optimize your health, or plan a path forward after stopping.
Low energy or poor health—if you simply don’t feel as well as you’d like and want expert guidance on sustainable change.
Note: If you’ve been diagnosed with type 2 diabetes, or are currently taking insulin or diabetes medications, our Diabetes Remission & Regression Program will be a better fit for your needs.

No. The program is a great fit whether you have an existing health issue like hypertension, prediabetes, or obesity, or are simply looking to lose weight and restore your metabolic balance and overall health.
The Metabolic Reset Program is designed to deliver measurable, sustainable improvements in both weight and cardiometabolic health. Results vary by individual, but the plan provides real help with some of the most common health issues and goals including:
Weight loss
Target visceral fat—the type of fat most dangerous to your health—while protecting lean muscle. Many participants also report improved satiety and a healthier relationship with food.
Blood lipids
Lower LDL cholesterol and triglycerides naturally, while supporting healthier HDL levels—reducing reliance on medication for many.
Blood sugar
Improve insulin sensitivity, balance blood sugar, and lower your risk for prediabetes and type 2 diabetes.
Blood pressure
Reduce blood pressure and ease strain on the heart through a nutrition-first, drug-free approach.
Over time, these improvements compound—supporting healthier aging, reducing lifetime healthcare costs, and helping you feel more energized, resilient, and in control.

During your first month in the Prolon Metabolic Reset Program, you’ll complete a set of baseline lab tests that provide insight into your heart and metabolic health. These results give us a clear starting point and allow our dietitians to tailor your program for the best possible outcomes.Here’s what we measure:
Complete Blood Count (CBC): Evaluates your red blood cells, white blood cells, platelets, and triglycerides. This helps us understand oxygen-carrying capacity, immune function, cholesterol balance, and overall blood health.
Comprehensive Metabolic Panel (CMP): Looks at kidney and liver health, blood sugar, protein levels, and electrolytes - important markers of how your body is functioning at a cellular level.
Ongoing tracking: Your labs aren’t just a one-time check. After your initial month, we repeat these labs every three months for the duration of your program. This allows us to measure your progress, make adjustments along the way, and ensure your nutrition plan continues to support fat-focused weight loss, muscle protection, and long-term metabolic balance.

Diets focus on short-term restriction, and drugs focus on symptom management. The Metabolic Reset Program is different: it works with your body’s natural processes to create lasting change.
Activating your body’s own ability to heal.
Science-backed
Built on 25+ years of longevity and nutrition research, the program uses the patented Prolon Fasting Mimicking Diet (FMD) to trigger cellular renewal and target visceral fat while protecting muscle mass. No guesswork, no gimmicks—just proven results.
Muscle protection vs. muscle loss
GLP-1 drugs (like Wegovy or Zepbound) can deliver weight loss, but studies show up to 40% of that loss may come from muscle, slowing your metabolism and making it harder to keep the weight off. Prolon’s nutrition technology helps you lose fat while protecting your strength.
Drug-free, side-effect-free
Unlike injections that can cost $350–$500 per month, may come with serious side effects, and may require ongoing use to maintain results, Prolon is drug-free. The program activates your body’s own ability to heal, and delivers sustainable results. No needles, no nausea, no long-term dependency.
High tech + high touch
The program pairs rigorous science with expert, 1-on-1 dietitian support and lab tracking, so you’re supported as you progress toward your goal. That combination of evidence and personal guidance is what makes the results both real and sustainable.
In short: it’s not another crash diet or costly injection. It’s a clinically proven way to reset your metabolism, lose weight safely, and improve the health markers that matter most—without trading one problem for another.
