There is no reason why you can't say that you are on OWL rung 4... It's up to you what amount you keep your carb count - you can also add the foods from OWL rungs 1, 2 and 3...
I'm on rung 3 and thinking about hopping up to rung 4 to have some frozen fruit with my yogurt smoothie... However, I'm usually around 16 carbs per day because that's just what I eat...
At your weight, you could probably reduce your carbs with just about any foods and still lose... there will come a time when you stall and then you might have to make some changes... but up until then, enjoy the ride downhill!
