I saw this show on the TV the other week about how long you have to walk to take off a McDonalds meal deal it was like a full marathon. Just shows you how calorie laden some of those fast food meals are. A quick binge can feel so good at the time but a few seconds later you feel like such an idiot. If only you could get that feeling before the binge starts it would save alot of guilt and lamenting.
Anyways over the long haul you can easily make it up if you add say another 5-10 minutes of regular low impact exercise in your day just by doing little things in your every day life; like stairs, playing with the kids etcertra.
