What episode of King of Queens...?!

has Carrie complaining about Doug's weight and he agrees to go to a weight loss meeting but ends up going to a meeting for abused spouses across the hall in the same building!. He sees free refreshments and starts to gorge on the food while playing the poor abused husband!.
I didn't see the whole episode but what I watched was hilariously funny and I've searched to find this particular episode and haven't been successful!.

Ten points to the answerer who can name it or tell me what season it is from accurately!.!.!.Www@Enter-QA@Com
