Trying To Slim Down For Disney World

I am back at the blogging thing again. I am trying to get in better shape because my wife and i are going to go to Disney world in December and there will be a lot of walking and i want to make sure I can fit in all the rides. I am going to try and do a daily post of my eating and exercise for the day to try and keep my self accountable for what I eat and how much I exercise. I will also do a weekend round up on Monday mornings. I plan on posting my starting weight at the begging of August, or as close as my scale will get to a starting weight. My hope is to be close to 310 by the time we go to Disney World at the beginning of December. That means I will probably need to lose around 25 pounds in 4ish months. I don't know if that is do able but I am going to try.
