I know when I first started cad I didn't really balance. But I did keep carbs out of my cm's. As the book says 1/3 protein, veggie and carb. I add more protein if I want more carb. Veggies have carbs too so be careful if eating carby veggies...I would count those as my carb too.
I have about the same amount of weight to lose as you. Hopefully we can get this done! It is a great plan!
