Hello Kate Fogarty,

There is some basic guidance and FAQ for newbies in this useful thread:

As for your question about hunger, no, you don’t have to feel hunger to burn fat (you switch to fat burning most nights when you’re asleep). You might feel a little hunger while you’re adapting to a 500kcal or 0.25 TDEE (see Newbies thread) intake on your FD but you may well adapt to that quite quickly.

Good Luck with integrating fasting into your new WOL.
