The only nutrition program patented for supporting longevity and protecting lean body mass through cellular rejuvenation.
Designed from decades of longevity research— products made to sustain your results and support energy, muscle, and healthy aging.
PROLON 5-DAY FASTING MIMICKING Diet
The most powerful changes come from within. That’s the science-backed principle at the heart of Prolon’s patented 5-day program. You get the benefits of fasting while eating nourishing food.
The only patented nutrition program that triggers your body’s natural cellular cleanup process and supports longevity.
Clinically proven to target visceral fat while protecting your precious lean muscle.
Supports healthy metabolic markers. 20 days of the 5-Day FMD is as effective as 120 days of the Mediterranean Diet for heart health.
Age on your terms. Three cycles of the 5-Day FMD reverses your biological age by 2.5 years.
By mimicking fasting states, the clinically tested FMD initiates cellular rejuvenation and targets visceral fat. It's your periodic deep clean and systemic overhaul.
