Where Do Bad Moods Come From? | Wired Science | Wired.com:
"The standard theory of bad moods is rooted in a psychological quirk known as ego depletion. Pioneered by Roy Baumeister and Mark Muraven in the 1990s, the basic idea behind ego depletion is that self-control and willpower are limited cognitive resources. As a result, when we overexert ourselves in one domain – say, when we’re on a strict diet, or focused on a difficult task for hours at work – we have fewer resources left over to exert self-control in other domains. This helps explain why, after a long day at the office, we’re more likely to indulge in a pint of ice cream, or eat one too many slices of pizza. A tired brain, preoccupied with its problems, is going to struggle to resist what it wants, even when what it wants isn’t what we need.

A bad mood is no different. When we push our mind too hard, asking it to refrain from carbs and cigarettes, we struggle to avoid the negative thoughts and emotions that lead to sour moods
