Are you following an actual diet plan or have you just cut out bread, pasta, spuds- obvious? There are carbs in most veg in varying quantities and sugars in drinks etc which can have an effect if you're looking to go into ketosis.
I can cut out the starchy foods and feel a lot better but the weight doesn't shift unless I apply myself properly and be really strict! I'm not selling anything, but I did 'golower' before Christmas, it's quite dear and you're paying to be babysat and sent all your grub but it does get results. In 6 weeks you could expect to lose 1.5 stone.
