I gave my mom the Ideal Weight and she started listening to it mid-July. She loves it! She has lost about 20 lbs since then. She listened to it everyday for the first 8 or so days and now listens to it about once every three days (she has other paraliminals that listens to on the other days for other goals). The last few weeks she's lost 1 1/2 to 2 lbs every week. She said it's been almost effortless to eat smaller portions and stop when she is full instead of eating just because it is there.
Hope this helps.
