I never had a sweet tooth, so I don't miss any of the cakes, chocolate or whatever. I went through a bizarre phase where I wanted marshmallows. I mean; marshmallows?
I sorted that out by eventually buying some sugar-free marshmallows, but they turned out to be cloyingly sweet, so I was over that little phase PDQ.
I don't miss salty snacks as I can have plenty of those, albeit not too many Salsa and Mesquite Kettle Chips. The Sunday roast had the most magnificant, slowly rendered crackling which, stored in an airtight box, on kitchen roll, it was fine yesterday. Kale steamed briefly, then laid, seasoned, and put onto a baking sheet, in a 150c oven for a few minutes (maybe 10-15) desiccates beautifully and creates a salty, crispy snack.
I don't have all the same things as before, but they're just different delicious snacks.
There are so many options out there.
