SAD doesn’t simply stand for the usual American weight-reduction plan.
There’s a situation often known as seasonal affective dysfunction that’s characterised by elevated urge for food and cravings, in addition to larger 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 habits. We seem to eat extra as the times get shorter. There’s a “marked seasonal rhythm” to calorie consumption with larger meal measurement, consuming price, starvation, and general calorie consumption within the fall.
In preparation for winter, some animals hibernate, doubling their fats shops with autumnal abundance to take care of the next shortage of winter.

Folks blame the vacations for overeating, however it could be that “reasonably than the vacations inflicting heightened consumption, the seasonal heightening of consumption within the fall might have brought about the scheduling of holidays at the moment.”
Regardless, as you possibly can see beneath and at 2:15 in my video, different “particular suggestions for the prevention of weight problems and metabolic syndrome by bettering the circadian system well being,” primarily based on various levels of proof, embody: sleeping through the evening and being lively through the day; sleeping sufficient—at the very least seven or eight hours an evening; early to mattress, early to rise; and quick naps are nice. (Opposite to standard perception, daytime napping doesn’t seem to adversely impression sleep at evening.) Additionally really helpful: avoiding brilliant gentle publicity at evening; sleeping in complete darkness when potential; making breakfast or lunch your greatest meal of the day; not consuming or exercising proper earlier than mattress; and utterly avoiding consuming at evening.
