I may be the exception but I have lost 84 pounds while taking Seroquel. I follow the UK based Slimming World plan and I certainly don't go hungry. I used to take lithium but it was stopped before I started my "diet".

I am not exactly active but I am trying to be more active since I reached my target. My diet is basically a healthy low fat diet. I eat far less processed foods. I really cut back on bread and the associated spread or butter. I now use only skimmed milk. I eat lots of veggies.
