We get addicted to the positive feed back of decreasing weight and increasing fitness. The fact is, as Neil pointed out, we need to focus on the trend.
Get back on the program, now. Not next week. Nor, in a few days. But, when you wake up. Start with whatever your program is. I count calories. In the morning, start doing what you do.
