I am starting it today! After doing atkins for like 6 months, I started to develop some digestive system poblems, so I am switching to SBD. I think A major problem I was having was eating too high of fat. Also, it appears to me that the 1st stage of SBD is very similar to atkins induction (a bit easier in that you don't count carbs and that nuts are ok) and then that stage two is very similar to atkins for life, just with lower saturated fat and potentially higher carbs. It makes more sense to me, but thats just me!
