That's certainly an improvement, but still involves me planning to eat in half an hour instead of just snacking right now. But I shouldn't be presenting myself as representative of any demographic except maybe bedroom coders. I tend to agree that junk and expense correlate. I don't eat junk, I eat random crap, it's very different.
In any-event. It is objectively more expensive to buy junk food, that includes the cheaper junk. Once I cut out the trips to the takeaway and the deli, I was surprised at how much more money I had per month.
The fact is that people tend to want to eat junk.
