I might have read something that suggested counting calories causes greater slimness. I think a smartwatch with side cameras could, without effort or even waving it around a plate, could image food. The deep AI which approaches, or possibly now exceeds, humans at identifying images figures out what food it is and how much of it there is. Then the app counts calories and tells you how many remain. Perhaps it beeps majestically to warn people if a soda is present.

They were looking for something new to do with those watches.
