Lighten the load

I was looking at some older pics pf myself and have come to the realization that I want to look like I did a couple years ago again. It is totally possible to drop the few lbs to get there. My problem will be sticking to a weight loss routine, especially when the gf cooks for 20 when there are only 2 of us..lol So, I'm going to weigh myself on Sunday, which will be a scary number, and keep a track each week until I'm at a weight or look like I want to. I'm ok with where I am right now, but I really don't want to have to go out and buy new clothes. I'm on the verge of my clothes not fitting. so, you can say this is an economic thing. Wish me luck!
