The Benefits of the Fasting Mimicking Diet
Science-backed benefits. Lasting results.
Prolon works with your body to deliver lasting results across many key areas of health—renewing your body and mind from the inside out.
Fat-focused weight loss
Unlike most diets and injections, Prolon protects lean muscle while targeting fat—especially visceral and abdominal fat. The average user loses around five pounds after one cycle, with reductions in waist circumference, and the weight stays off.
Learn more ›Healthy aging & longevity
Proven to trigger autophagy, helping cells act like younger versions of themselves. Three consecutive monthly cycles have been shown to reduce biological age by 2.5 years.
Learn more ›Cellular renewal
By activating autophagy—the body’s natural cellular cleanup—Prolon helps cells reset for healthier, more youthful functioning, driving the wide-ranging results users experience.
Learn more ›Skin health & appearance
Helps rejuvenate skin from within—increasing hydration by 25% while improving tone, texture and radiance after three consecutive monthly cycles.
Cardiometabolic health
Supports key metabolic and cardiovascular markers. Clinical studies show 20 days of Prolon deliver heart-health benefits comparable to 120 days on a Mediterranean Diet.
Mental & emotional well-being
A mental reset: users report reduced cravings, healthier eating habits, greater mindfulness around food, and a stronger sense of control over their health.
Energy & mental clarity
After the 5-day cycle, many report feeling revitalized—with improved energy, sharper focus and greater mental clarity supported by cellular cleanup and ketosis.
From the pioneers in longevity science
Prolon is the only nutrition program patented for supporting longevity, healthspan, and protecting lean body mass through cellular rejuvenation.
The power of three: how to maximize results
While even a single cycle of the 5-Day FMD offers numerous benefits, research shows that repeating cycles builds and sustains them over time. The most effective approach begins with three consecutive monthly cycles, then three to four cycles a year. Clinical studies show this can reduce biological age by an average of 2.5 years after three consecutive monthly cycles, with the potential to reduce biological age by up to 11 years over 20 years when practiced annually.
