From my research and myself..if you don't exercise regularly..at least 4-5 days week, and break a sweat, you won't keep the weight off or lose very fast. I plan to prove this theory ...! I believe maintaining a healthy weight is 80% exercise and 20% diet. This is something I learned as a kid being an athelete (figure skater). All the people we would see that quit figure skating, all of them got heavy within a few years because their metabolism wasn't stoked from exercise anymore. You have to stoke the fire!
So I think eating with the CAD and keeping the blood sugar even and the exercise would be super charging the whole program.
