I know I always seem to beat myself up when I have a week in which I gain a little weight, but other than the fact that it delays my reaching my ultimate goal, the minor "setbacks" really don't bother me that much. I typically step on the scales every morning, despite the fact that most "experts" say one shouldn't do that when engaged in a weight-loss plan. When I was at my heaviest, my weight would fluctuate as much as 5 pounds from one day to the next. One morning I would weigh 263; the next, 258. The day after that, I might be back at 261. So, I know that minor fluctuations aren't that big a deal.
In fact, this morning, the scale read 222.5.
