Think I'm similar to you @bigfootfred I'm guessing I'm around 83kg at the mo, not too sure though as I'm basing that purely off of my last weighing seconds before DC3 was born 7 months ago
aiming to get down to 58kg so I've a long, long way to go, but hoping once my scale batteries arrive, that my weight right now might not be as big as I'm thinking, orrrrr it could go the other way, oh no!!
I'm about to do to 10k on my exercise bike, but if my three DC's are playing happily, I'll push for 13k, then I'll be having an omelette and some rice cakes with houmous on at 10am, ending my 16 hour fast 
With regards to food - I sent DH to the shops yesterday with a little list for me, mostly consisting of veg, maggi oven bake bags which are great for flavoursome chicken! Nuts, crackerbread, rice cakes, houmous, oats etc. My biggest downfall diet wise is pasta and potato, but so far I'm coping well without both - she says as she sits here dreaming of a goopy Mac and cheese bake topped with golden, crispy cheddar cheese 😂🥴🤦🏻♀️
