How can i use the secret to slim down? The first thing is to decide: I want to be healthy, i want to be trim. Get clear on the best weight for you. Then write it out and place it over the readout of your scale so that you don't see the actual number, you see "125" or whatever your ideal weight is. Look at pictures of your self not at that weight. Really picture your self. What are you wearing? Are you smiling?
