I have heard something similar about the connection between stress and metabolism.
I can't remember where I read it (probably in one of the 10000000 articles on the internet I"ve read in the past 2 months) but stress will seriously affect your brain functions as well as your adrenal functions and pretty much everything else in your body. That is why, a lot of people who work out and eat heathily will gain 5-10lbs just because of stress alone.
I guess there was a study of people working at stressful jobs losing weight. The people who took a week off to relax and stuff lost weight 75% faster than the people who did not take a break.
Hrm.. Maybe I won't go back to work this Thursday...
