I noticed that the graveyard shift is one of the thinnest shifts everywhere I've worked.   Same! You know what a thin old guy at my previous job had for lunch every day?  One of the steamed vegetable bags /u/AcidicBitch uses with a bit of MSG sprinkled on.  I never, ever saw a fat person eat those.  But people made sure to tell me "ShitArchon, that diet soda is bad for you!  It gives you cancer!"
