working out and eating right

Working out and eating right are things I do not do best. Well eating wise... I just love food, I eat fruits, veggies, and healthy food but I really love junk. As for working out.......... I think my record is 3 days then I quit/give up. I feel like I need instant results which of course doesn't happen. When miss A was born I lost 30lbs instantly and in the 13 months since she was born I have not lost anything. We find ourselves cooped up in our apartment because there is nothing to do in the complex and I do not feel comfortable going outside the complex with just miss A, (there really isn't anywhere to go anyway) Like my excuses? So I am going to start a food journal (because I feel like I do not eat very much). As for the working out, as soon as miss A goes down for her nap I am going to do 20 minutes a few times a week for the rest of the month as a short term goal. Sound good? I think I can do it.  (I could handle losing another 30 pounds)
