After reading both books, CAD is much less restrictive than CALP, but if you like order in your life, CALP is probably the better way to go. Less choices, it seems.

CAD, to me, is simple.

1. Very lo carb breakfast
2. Very lo carb lunch
3. Well balanced dinner with option to have carb of choice or induldge in a treat, if you so desire. (Reward Meal)

CALP is a little more laden with rules (i.e., salad is a must before each RM. 1/3 veggie; 1/3 protein; 1/3 carb for RM...)

Good luck. I find it very easy for the most part. Not a hard WOE to follow.
