Check out Dr Amanda Sainsbury-Salis and Don't Go Hungry. She has a lot about starvation mode and resetting your fat switch. Getting to know when your are truly hungry.
Basically if you are truly hungry eat, eat what your body is craving to be point of satisfied. It may take one meal, a day of eating or a week of eating, to get your body back out of thinking it in starvation mode.

Probably similar stuff to what you are reading.
