I'm not an atkins person, but I thought I would give a bit of info that is in TSP 2, that you can actually gain weight if your body has a very badly damaged metabolism before it will correct. That maybe something you are going through here. The atkins group will give you great support, but the other thought may help you through this. Don't give up, just remember what has not worked in the past and that is High Carbs.
