If you work on Wall Street, chances are you will at one point pull an all-nighter.

Cancel your dinner with your friends. You’re about to put your body and brain through something awful.

There are two opposing hormones in your body that regulate your appetite -- leptin and ghrelin. In individuals who lack sleep, the body produces less leptin and more ghrelin which makes you hungrier.
Scientists from Stanford and the University of Wisconsin noticed that after one night of little to no sleep, a person's body mass index increases.
According to study in the US National Library of Medicine and National Institute of Health, sleep deprivation affects your brain's frontal lobes, slowing down their communications.
In terms of concentration that means you are impairing your spacial, auditory and visual attention. And forget about doing anything monotonous for a long period of time.
Working memory can be divided into four subsystems: phonological loop, visuospatial sketchpad, episodic buffer and central executive. The phonological loop is assumed to temporarily store verbal and acoustic information (echo memory); the sketchpad, to hold visuospatial information (iconic memory), and the episodic buffer to integrate information from several different sources.
All of those are connected to how well your frontal lobe works, and that takes a hit when you don't sleep.
According to a UC Berkeley study, sleep deprivation boosts the parts of your brain that are associated with depression and cause you to overreact to negative experiences. It also hampers the prefrontal lobe (as you know) which helps to regulate emotion.
