A bit discouraged

First, I had dessert on Sunday. Two bite/fun sized chocolate candies and a small frosty. More on the dessert later... I am feeling discouraged today. It seems like I keep taking one step forward, then two steps back. I had my lowest weigh in yet on Sunday morning of this week. I was so pumped about it that I texted my sister and challenged her to a little biggest loser contest for this week. Well, the next morning I woke up a pound heavier. The next morning, another pound up. And today, about the same as yesterday...maybe even up a little more. I looked back at my desert the dessert post I wrote over a month ago. As of this morning, I am only down about 1 1/2 pounds from then. I can't lie; that number is not encouraging. I know I have had some bad days, but overall. I feel like I have been doing well. I have maybe eaten dessert once a week and been exercising 3 days a week. I even had my furthest run yet yesterday at 4.2 miles. I just feel like I am trying with little to show for it. Anyway, my commitment was to eat no desert except on certain occasions until I lost all my weight. I would like to modify that a bit today. Instead of certain occasions that I list in advance, I am going to change my commitment to no more than dessert one day a week. If I have dessert more than once in a week, I will mention it here on my blog. I will go ahead and say that I plan to have dessert two days this weekend as it is my birthday and Fathers Day and we will be celebrating with family. I think in order to really lose weight, I have to consistently count/journal calories.
