Oh, very FEW people deal with the root, just about everyone who doesn't maintain their losses, in fact. There is a reason the percentage of maintainers is fairly small and it isn't because weightloss is PHYSICALLY impossible to maintain, I can tell you that much
Let me make you feel better, or empathize a bit? I had an INSANE night tonight, and everything that could have gone wrong kind of did, in terms of controlling my eating. I ate off plan food and too many of them, because I used food to mask my stress and nervousness and just shoveled in, rather than dealing with the emotions with my brain I used my poor body as a shield. That is NOT conducive to weight maintenance and isn't healthy behavior.
What I should have done, and will begin to do right now, as it is over, is to go over what I did right and what I did wrong in my choices that led me to this end. Then I will reinforce or tweak my plan of action so that my very next choices are going back in the direction I need them to go. I had reasons, sure, and excuses, but in the end tonight I made the wrong choices and recognize that, so now I can do better going forward. I'm still pretty new to complete intuitive eating and using NOTHING but physical cues as my guide, so a few slip ups are to be expected, but I already see ways I can minimize this from happening even more in the future. Tomorrow, first chance I get upon waking, I can do better.
That is how you turn this around - make different choices, analyze and plan a better course of action. Forgive yourself for the failure but resolve to move on in a positive, goal achieving direction instead of declaring it a failure or yourself powerless to the circumstances you are in. We always have a choice, we don't always make the right one (like me, tonight!), but we can FIX that! Isn't that awesome?!
