It appeared from what little I read on seth robert's blog that one has to continue the flavorless calories indefinitely. The setpoint doesn't really "stick". People gain weight when they stop. Could be a lot of reasons why they gain weight, like they stop so they eat more, but I don't really know. And I don't know for sure if the not "sticking" thing is the same for everybody.
Yesterday I was looking for MCT oil (didn't find it) and found coconut oil capsules. I considered buying them because then you would not taste the oil at all. But they were way too expensive.
