I've been doing 16:8 for decades without knowing it was a thing :) For me it basically burns down to skipping breakfast, eating lunch at 12:00 and dinner at 18:00, and that's it.
I did 5:2 for 3-4 years as well, and lost 20kg (~44 freedom units). I did 36 hour fasts, and after a while it just felt naturally, but i'd be lying if i said the fasting days were easy. It gets "easier" but never easy.
I usually took a break from fasting during holidays, and a few years back i never really got back into it, and reverted to my old 16:8 ways. I'd love to see more research on it, but from my own experience, it's nowhere as effective as a regular 5:2 diet.
