I did a WW/SBD combo before WW came out with the core program and it worked quite well. I just incorporated the SBD menus and recipes and counted the points for them.
I find that if I eat a lot of rice/potatoes/bread I tend to gain. The great thing about SBD was that it encouraged eating fresh food and cooking for yourself.
I still eat like that and stay away from processed foods and pre-packaged meals and snacks.
I'm sure you could switch over and still eat lower carb if you follow the Core Program or make menus for yourself that have less carbs.
