Over the past 5 years I have gone from weighing 210 to weighing 120 today. I did so by moving more, eating less and being treated for depression. Counsling helps ALOT. Food doesn't make you fat, you make yer self fat. If you have a physical issue, changing your diet can help, prolly will help. But instead of reading a book, try listen to your own body. What makes you feel nurished and healthy. what have you eaten when you experience dificulty. if something makes you feel yucky, don't eat it for a while. IT IS YOUR BODY! it tells you stuff everyday, if you listen. No DR. or natropath, or LMT or any health care professional knows more about or can moniter your body better than you can.
