SAD doesn’t simply stand for the usual American weight loss plan.
There’s a situation generally known as seasonal affective dysfunction that’s characterised by elevated urge for food and cravings, in addition to better sleepiness and lethargy, that begins in autumn when gentle publicity begins to dwindle. This now seems to symbolize the far finish of a traditional spectrum of human conduct. We seem to eat extra as the times get shorter.
