What a load of absolute crap. Substitute "vodka" for "carbohydrates" and "being sober" for "Atkins", and the ridiculousness is a little more obvious. 12 weeks is *barely* long enough for your brain chemistry to sort itself out from its life-long carb addiction. Come back when you've studied people for at least six months. Think about it: even antidepressant medications take WEEKS to have an effect.

>>"Some were given a high carbohydrate diet and others ate more protein-rich foods."

More protein rich foods? That's it? That's how they sum up the Atkins plan?

I've suffered from depression since I was a teenager and spent YEARS self medicating with (alternatingly) junk food and low fat dieting. I've been virtually CURED by low carbing. I know I'm not alone in this one. There are too many people like me to across-the-board imply that LCing causes depression.
