I used the Potatoes not Prozac program and feel it really helped lift the low serotonin type of depression I had. I would never have gotten out of the hole by going right from carb overdosing straight to low carb, and I know that because I tried that exact thing dozens of times.

To this day I follow a program that allows 50g of carbs even from (gasp) potatoes and I feel great all the time.

I also had to take omega3, vit D, and minerals (iodine and magnesium) for deficiencies also.

I think that once my brain had been so disregulated from carb overdosing, it would never have been enough to just stop the carbs. I had to add in sat fat and protein. There are more elements to restoring a healthy brain - the right protein, fat, and carb, and also minerals, sleep, and behavior too. (like quitting the drama crisis making)

I do have to watch the amounts of fat and carb to lose fat; it's easy to overdo it when I don't exercise all that much.
