Ice milk was pretty disappointing – more of a tease than a treat. I think I have similar feelings about sherbet for that reason. It was foisted off on me as a lo-cal alternative to ice cream.
I was big on Special K as a small kid, especially with skim milk and about a quarter cup of cyclamate poured on top of it.
Here’s another one from that era: Hollywood Diet Bread. Mainly diet because it was sliced about 1/8th of an inch thick and only slightly larger than a graham cracker square.
Remember the diet plates at most luncheonettes? A scoop of tuna, chicken or egg salad, a scoop of coleslaw and another of potato salad. Usually each sitting on a small white piece of iceberg lettuce and garnished with a sprig of parsley. And a packet of melba toasts. What on earth made people think that mayonnaise was a diet food?
