Day 1. This time around I started exercising the first week of induction, but when I did Atkins the first time, I was already working out regularly. As Atkins says, its non-negotiable. Walking is great, you don't have to run a marathon, just be active.
You can also incorporate activity into your daily life, like walking around every time you are on the phone, parking far away from the store and taking those extra steps....it adds up
