Why not just adjust your eating - make sure you have no biscuits, cakes etc in the house. Stock up on your favourite salad ingredients. Make soups. I put cut up vegetables with some stock, tinned tomatoes and puy lentils in the slow cooker. Eat things like grilled fish/prawns etc. Chicken/eggs/cottage cheese. Start day with porridge or cereal with banana and strawberries on top. My downfall is wine and if I dont drink for a few days my scales show a difference.
You may prefer to be on a diet, but I lose interest when I try to start them.
