I'm with you with the problems about feeding kids and somehow trying to feed me too, as I have 9 and 12 year olds, one of whom is a pasta-holic.
Sometimes two meals occur. Sometimes I forget myself and eat only what I can off their meal (ie the meat!). Sometimes I have the best of intentions to cook twice and after their bedtimes I lose all will to follow that plan and either starve or do the worst thing possible and start snacking on cereal. Cereal is incredibly bad for me, as I've discovered. Incredibly bad.
There's a lot of trial and error involved in figuring out what works for you and what foods you can/can't eat. Very bizarrely, my children now love stir fries. Lots of meat, lots of good veg, and there are some nice low-carb sauces out there (but you have to read the labels, as they're not advertised as such). The kids have rice with it. I don't have rice. When I'm feeing rich, I have Oomi noodles from Ocado/Waitrose (they're fish protein noodles, which sound disgusting, but aren't and they're a good alternative to regular noodles). But now the kids like them too, which is not fair as they're my noodles and expensive.
The kids also like my Oppo ice cream.
They don't like the LivLife bread.
Or cauliflower rice.
I'm kind of with them on the last one.
My 9 year old is now tuned in to what I can and can't eat. You'd be amazed (possibly not) at how children can be annoying if you give them a task! My son now tells me off when he sees me eyeing his crisps in moments of weakness, and offers me nuts instead. And when that doesn't help, strawberries with 10-cal jelly, slathered in double cream with dark chocolate grated on top (that's my go-to dessert). The kids like that too.
