Personally when I get off track for whatever reason, I don't focus on why because in reality all that matters is that I allowed something or someone else to interrupt my personal agenda and failed to do what I needed to do for myself. Instead, I tell myself it's time to get back on it. My motivation varies from: looking at pictures of when I was larger, trying on "that one dress" to see every milli-inch I want to get rid of before I step out in it, or just putting on music to fit my mood and jammin' out while workin' out. As far as my eating habits, I eat what I want in moderation. If I eat something fried one day, then I try to make sure I eat something baked or broiled the next few days. If I want Oreos, I eat two or three rather than 10 or one cupcake instead of two. I've also found that pre-planning meals help alot.
