Here are my thoughts on it...
It could be the weightlifting. I mean, I can actually feel a considerable difference in my muscular readiness to conquer the staircase. Whenever we climb stairs at work I'm always far beyond my coworkers, but that's always the case, even when I'm unhealthy. The way I deal with stairs is to get past them! Lingering on them just prolongs my misery. Anyway, maybe there has been significant muscular weight added.
It could be the cheats. I have not been strictly adherent the way I used to be and wanted to be again. A couple of nights, right before my period, I stopped by the convenience store for a sweets binge. Sometimes I also skipped meals.
It could be all the inactivity. I stay up all night lying in bed playing video games and then sleep, so that's a lot of time lying down.
It could be that I'm scheduled for too many calories. Since I told ediets I was working out 3-5 times a week instead of 1-3 times per week, they upped my calories to 2000-2200 from the 1500-1700 I used to do when I wasn't exercising. For one thing, it's more food prep and more expensive groceries! I always used to cheat a little bit on the size of my fruit servings but since I was losing weight I didn't worry about it. Now if I'm scheduled to eat even more calories, then maybe overestimating my portion sizes is killing my results on the scale.
I'm going to stick with the exercising, and keep up the weightlifting for at least a little longer, but if I don't see a loss on the scale, and my clothes don't start fitting better, and I don't feel little hollows in my body where the fat used to be, I will ask ediets to reduce my calorie budget. And if that doesn't work, I will consult an advisor at the Y and consign myself to his or her advice/program.
I have to believe that this is going to happen for me again, but it just might have to hurt a little bit, and sometimes life distracts my focus.
