Personally, I notice I have forgotten some of my basic principles. The most basic, SLOW DOWN WHEN I EAT. Be conscious of each bite and chew it or savor it before I ingest it. Think about the next bite before I take it. I have been able to avoid second helpings, dessert, snacking entirely by using this and in turn keeping my caloric intake down.
Also something I still do is weigh and log the number daily. It's a lot easier to grab that one pound and smack it than to "discover" 10 that need to go.
