Plateaus... how the heck do I get over it??!

I started at 339 and am down to 203... I had hoped to be under 200 by New Years but that didn't work. I am walking about 6 miles per day and doing aerobics 3 x per week but my scale hasn't moved a bit. Any suggestions? I'm drinking plenty of water and I allow myself to have some carbs now and again but I figure with all my exercising I should be able to get away with it (maybe not, huh?). Any ideas w/out having to cut the carbs out completely?

Quick join the P/B challenge! Then we could be the Fabulous Fourteen!! See message below yours. Judy

Marta, Come join us in our P/B Challenge. I can only answer for myself. When I do carbs I stall or gain. Everyone is different . You are about with the rest of us. Weight loss has really slowed or stalled. We are doing this 4 week challenge to get back to basics and get a jump start on weight loss again. Feel free to join us. See you lighter. Joanne

What is the P/B challenge? I'm game, but somebody please explain what I need to do. Thanks for your help.
