Weight Loss/ Military Training

Well here is day one, kind of odd that I am starting at night. But this just got way out of a control, I have  been "trying" to lose weight and in turn I have gained weight. almost 40lbs since spring. This is just ridiculous, so my goal is to get in shape, be able to run 10k in 13 weeks, and get prepared for military. Now the funny thing is that supposedly the world is supposed to end before christmas. If so then I'll die with a positive goal in mind, and if not then I will follow through and keep going with my goal.
