Doc did some changing arounds of meds on me. When she put me on Celexa (depression/anxiety/ocd/phobia) I started losing weight without making any other lifestyle changes.

Otherwise I used to follow a low blood sugar diet {6 meals per day} and I would lose weight really well. Plus I just felt better. Teaches you what a real portion size is too.
I got all the info off the internet and printed everything out. then I kept a log of how many servings from each food group I had for every meal. I was only allowed 1500 cals a day. It goes by exchanges and is easy to keep track of.
