Fostering a Change in Lifestyle

What exactly is a change in life style, and how does one bring that about for one's self, in a lasting and meaningful way?

But I was using eating as something to break up torpor - or boredom or disinterest or something to do... due to lack of interest in many things. Why the disinterest? That is a self protection method of growing up without, if I had anything, it was taken away and given to others or used. It was a form of abuse. It is easy to not care, not want, not desire, and disappear into my own head, into a world of unreal thoughts, a fancy work where I did not need to deal with doing the things I did not like, that gave me no satisfaction, and caused pain, distress, frustration, and the like.

But what do I know?
