Hi Molly!
Welcome!
Just remember that a lot of people have a frustrating time going from Atkins to CAD/CALP. You may gain a couple pounds initially as you build up your glycogen stores. Weight loss is also slower verses Atkins. Just give it the full 6 weeks like you said.
I was on Atkins for several years and I believe going too low in carbs lead to my hypothyroidism and ultimately made me fatter than ever. CAD/CALP is the perfect solution for me: moderate carbs while implementing some sort of restraint (I need rules and guidelines!) yet also having the freedom to eat my comfort foods once a day without guilt.
Good luck and keep us posted with your progress.
