TSY, it frees up a lot of time, i’m persuaded it has various health benefits, and it’s pretty cool to be able to go 20+h without getting tired or ratty about not eating if the need arises.
I should add it took me a good three months or so to be comfortable regularly eating once a day.
Martin Berkham does a far better job of rigourously explaining the science behind why (he believes) intermittent fasting is a good idea than i can. See the link below if you’re interested.

i followed leangains to strip bodyfat and found it quite easy. basically its always gonna be cals in vs cals out and eating in a deficit to lose weight, but IF (and leangains in particular) makes it easier IMHO.
i then decided i was too skinny and wanted to gain weight but still using IF (basically, 8hr eating windows, 16hr fast) but i just wasnt hungry enough in those 8hrs to eat surplus cals. so i just ate what i wnated when i wanted. and put on too much round my waist 🙂
im now doing IF again to lose a bit and will then have another bash at putting on lean mass.
waffled on a bit there, but basically its a healthy (yes really) way of eating less food each day. its better if you can stick to it as a lifestyle choice, because as finbar says, it frees up time and is just soooo easy 🙂
as well as the leangains method (16/8) theres also the idea that having 2X24hr peiods per week zero calories works too. which it does as i also did that once upon a time 🙂 sounds harsh, but really its just having evening tea, nothing else that night, miss breakfast, get hungry bout dinner, see it through, then eat tea again. and then eat as normal 5 days per week. obviously less cals consumed that week.
both ways work, are healthy and i found easy. HTH.
