I've done both now CAD and SBD and while they are similar, I think that I prefer SBD for the long haul.
On CAD you could only have carbs at one meal per day and you could eat as much as you wanted as long as you kept it within one hour. With that I tended to get carried away and sometimes made my "hour" one big binge, which is certainly not the plan of the WOE.
On SBD I feel less hungry, more in control, and that I'm having a healthy and balanced diet.
That's not to say that CAD doesn't work better for others and I did lose some weight on it, but I didn't feel that it was something I could do for life, and SBD is.
