I have religiously written everything down (via myplate) since January of 2011. I am currently on a weight loss plateau. I know exactly why. Too many calories. But at least I am not gaining weight. An experiment of maintenance. I figure that I will have to write down what I eat forever. It only takes a few extra calories a day to begin to slowly gain weight. Lifestyle change be damned. I can eat the right foods in what seems reasonable portions but it is hard to know how much you are eating if you do not keep track. Most people, including the non-obese, and including those who vigorously exercise, slowly gain weight over time. The formerly obese likely will gain weight faster than others over time. Vigilance is needed.
