Weight Gain

My god today I stepped on the scale and it was up .8 from yesterday. Yesterday work paid for lunch so I had one slice of meatsa meatsa pizza in two settings. It could have been from the pizza. It also could be from the fact that I haven't pooped in 2 days. Getting concerned about that now. I have to weigh in for the Dr. Kim show tomorrow and I wanted to be under 300. I'm so close to my first goal for myself. The weight loss is so damn slow right now though. I need to up my protein and start exercising and maybe those things will help.
