How many days a week are you doing the Yoga? I know, I've been losing inches and not pounds for the last 12 weeks. COD, will not let me switch down from RED to GOLD because I work out an hour most days. They know to expect at least one weekly tantrum from me over the scale! On Friday, they put one of the regional manager's who's also a trainer on the phone with me to talk me out of the insanity. The first thing she said to me is that as long as you're working out 5 hours a week you will not move below RED because they're isn't enough calories on gold or purple.
Best advice I can give you is to make sure COD knows what your realistically work-out, it makes all the difference in terms of what plan you're on. Ther's one counselor at COD that told me I shouldn't be working out if I want to lose weight.
However, COD manager preaches inches will always be better than dropping pounds!
By the way: I've lost 13 pounds and change in 12 weeks, but I dropped 15 1/2 inches in the same time. Typically it should be 1/2 an inch per pound that you drop. I'm dropping 1.23 inches per pound!
