I don't think you can "eat what you want" even with a pump. Which incidentally has to b connected to something under your skin

An insulin pump is not a magic device that allows you to eat what you like and dispenses the correct amount of insulin. This is called an artificial pancreas. These things are under development (using several different approaches), but they are very experimental. There have been a handful of human trials, but there are still formidable technological hurdles to surmount. My guess is that it will be at least a decade, and probably longer, before they become mainstream. However, maybe one day
