@snowsjoke , I think you are going at it with a sensible view
Make it work around your lifestyle
Im an alike so I dont eat syns. Also a lady of a certain age - weight loss is hard so 1/2 a pound loss a week and Im happy enough
I also have to cook for DH who is a builder, and mother who is 86, tastes buds gone and would rather eat cake. Not a mission I can stick to plan all week unless I cook different meals for everyone.
So I do what I can, when I can
My favourite snack - and main meal sometimes and brunch is yoghurt and fruit. Mostly I make my own yoghurt but I always keep in the free greekstyle mullers
A tub of that , a bowl of frozen fruit nuked, and if Im not using my HXB, sprinkle of granola
I also have light baby bels that I stick in pockets and handbags. Loads of times I go 8 to 10 hours without eating and they come in handy for a energy boost rather then a pack of crisps
Get your meals balanced and your need for snacks diminishes. But it's that bit that takes its time.
