Sleep less, eat more

Guru Magazine - - Body -

This strange change in eat­ing habits stems from an im­bal­ance of our hor­mones. When it’s time to eat, our stom­ach re­leases the hunger hor­mone ghre­lin. When we’re full, our fat tis­sue re­leases another hor­mone, lep­tin – let­ting us know we’ve eaten enough. Sleep de­pri­va­tion not only makes the lev­els of ghre­lin go up, but it makes lep­tin lev­els go down – ever widen­ing our gape for su­per­sized meals and sur­plus snack­ing. Our sleepy pref­er­ence for sweet and fatty foods can also be blamed on a shift in brain ac­tiv­ity: the re­ward ar­eas of our brain be­come over­ac­tive, while the de­ci­sion-mak­ing parts slow down. And what is more re­ward­ing than chips and choco­late?
