I'm into this new way of eating (healthy) for almost 2 years now and this past weekend was a total and complete disaster. Right back to my old ways. I planned my food out - but ate totally off plan anyway. I ate practically anything and everything in sight. It IS amazing how fast I could go right back to it, and after so long. With all the new, wonderful habits I have in place, the old fat girl is STILL there and I'm afraid she always will be.
But unlike the past, I was right back to it, stronger then ever come Monday. And THAT is the difference. Can't let it spiral out of control. Got to get a grip on it. One bad day or weekend or whatever can not turn into days and days and weeks. Had I had this way of thinking in the old days, there never would have been a morbidly obese Robin.
So yes, that vigilience and I think even more importantly, that right back to it-ness will make all the difference in the world. All the difference.
