What fellow Fasters' have to say

The Only Scientifically
Tested Fasting Diet®
ProLon is the first and only clinically tested, doctor recommended fasting meal program. ProLon’s breakthrough nutri-technology was researched for over 20 years and developed by Dr. Longo at The Longevity Institute at the University of Southern California with tens of millions of dollars in funding support from the National Institutes of Health. In 2018, TIME nominated Dr. Longo to be among the top 50 most influential people in health.

“Professor Valter Longo’s Fasting Mimicking Diet is the best beauty product and secret that I have discovered”

“I have tried pretty much every diet going and this is undoubtedly my favourite – because it works! Prolon is a ‘fast-mimicking diet’ that lasts just five days to activate the body’s ‘dormant ability to protect, repair and rejuvenate itself’. So it helps you lose weight but scientists say it can cut heart disease and cancer risks if done regularly too. You get five boxes of food – crunchy kale biscuits that I loved, filling soups, sweet nut bars and yummy, although small, chocolate bars. it averages out at about 800 calories a day. Not fun or easy but for five days it ISN’T difficult. I shifted weight that I’ve been trying to unpack for over A YEAR. Blood tests afterwards showed my visceral fat, ‘the dangerous stuff that wraps around your internal organs’ had dropped too. A month later I’ve put on ONE solitary pound. Best diet I’ve ever done and will do this every couple of months to keep on track!”
