What Our Clients Say...

I first got into Fasting when I met Jason at a calisthenics competition a few years ago. I could not believe he was performing how he was after fasting for 2 days. Very intrigued, I asked him about fasting, and how to get started. Jason is a very knowledgeable guy. He taught me about the different methods of fasting, fasting and feasting and how to fit fasting into my busy lifestyle as a coach and a calisthenics athlete. For me, Fasting helps with my mind, my physique and athleticism. I am now 3 years into this journey. I regularly fast 17-18 hours per day, as well as doing blocks of OMAD when I feel the time is right.
