I also fast with DH - it's a huge help having both do it. I think most of us find calorific values and track using My Fitness Pal, but there are calorie values at the back of Dr Mosley and Mimi Spencer's book and some great starter menus. Loads of tips and inspiration on here of course! Good luck.
Antidote I'm breastfeeding DD2, who is ten weeks. I have 750 cals on the first FD of the week (Monday for me like lots of us) and up to 1000 on the 2nd as I seem to be tireder on a Thursday as DD1 home all day!
