I find intermittent fasting interesting and have been observing it for 15+ years back when I was crushing WODs and eating Paleo in my CrossFit days.
My friends experimented with fasting and all seemed to enjoy it while in the process, but none of them stuck with it and it appeared to be a bit of a temporary fad. Or maybe it was a means to an end and they reverted back to traditional eating habits after reaching their goals. 
I’ve never tried intermittent fasting and have always been of the opinion that I don’t want to survive, I want to thrive. To thrive as a competitive athlete I need to fuel my body timely, fully and without restrictions. I will likely never be without food in life or on the bike. I also have no weight issues or struggle eating in competition.
So, fasting doesn’t make sense for me (even though I’m aware off all the science), but we are not all created equal. I enjoy and wish the best of luck to those who experiment what works best for them.
