WEIGHT LOSS

Lose fat. Protect muscle.
Keep the weight off.

Prolon’s 5-Day Fasting Mimicking Diet (FMD) harnesses the power of science to deliver healthy, sustainable weight loss in just five days.  

Target dangerous (and stubborn) fat

Weight loss isn’t just about numbers on a scale. Prolon targets visceral fat (like belly fat), the dangerous fat around your organs linked to heart disease, diabetes, and liver problems. Getting to a healthy weight and keeping muscle helps you live a healthier life, for longer.

Weight that stays off

With most diets, the pounds come right back. Prolon’s results last: studies show weight loss is sustained even after returning to a normal diet.

Muscle matters. Keep it.

Extreme diets and GLP-1 drugs can help shed pounds, but at the cost of muscle. Up to 40% of weight lost on GLP1s can come from lean tissue. Prolon is different: it’s clinically formulated and proven to protect muscle, so you don’t just look leaner, you support the very engine that drives metabolism, supports strength, regulates blood sugar, and helps make long-term weight loss and strength possible.

Three cycles = max results

One cycle delivers results, but the recommended protocol of three cycles per year (just 15 days out of 365!) has been shown to support long-term healthy body composition, weight care - and even a reduction in biological age. Keep it up quarterly to lock in the benefits.

Improve your relationship with food

Many users report greater awareness of their food choices following Prolon cycles, including improved portion control and a more mindful approach to eating. These shifts make it easier to sustain healthy eating habits, key drivers of long-term weight loss and weight management.

Prolon vs GLP-1 drugs

While GLP-1 drugs like Ozempic can deliver weight loss results, they usually come with a price—they’re expensive, dependent on daily use, and result in muscle loss. Prolon is different. With just three five-day cycles a year, you can achieve sustainable, drug-free weight loss that protects muscle and supports long-term health.

OUR PROGRAM

GLP-1 MEDICATIONS

Fat / muscle loss

Fat loss and muscle protection: Lose dangerous visceral fat—while protecting precious muscle.

Muscle loss: Up to 40% of weight lost with GLP-1s can be lean muscle, not fat. That can slow your metabolism and make weight regain easier.

Cost

Cost-effective: Programs start at $199, a fraction of what drugs can cost.

Costly commitment: Weekly injections add up, both financially and as a lifelong dependency.

Side effects

Drug-free, safe: The program works with your body's natural processes, not against them. No drugs, no side effects

Side effects: From nausea to more serious risks, GLP-1s may take a toll.

Sustainability

Sustainable results: The program resets your metabolism and relationship with food, for lasting results. Studies show that weight loss from our program stays off, even after returning to a normal diet.

No clear exit plan: Stopping GLP-1s often leads to weight regain, leaving you stuck in a cycle.
