Remember those massive King size Snickers bars of the not-so-distant past? Well, the gargantuan slabs of chocolate, peanuts, caramel, and nougat were quietly replaced by the resealable and shareable 2 to Go bars without many of us even noticing (via Market Watch). CNN states that the 2 to Go Snickers resealable package includes two smaller snickers bars containing 220 calories each. The move from King size to the 2 to Go package was officially announced in 2012, explaining that the new language and resealable packaging was meant to encourage consumers to share or save the second Snickers bar to eat later. The outlet stated that the confectionery company also said they planned to replace or eliminate all candy bar sizes which contained over 250 calories by the end of 2013. According to NPR, downsizing from the then standard two ounce and 280 calorie Snicker bars to a 250 calorie bar represented an 11 percent shrink.

Reason stated that Mars' decision to only sell lower calorie portions of their products was, in part, inspired by First Lady Michelle Obama's Let's Move! campaign, which was designed to help combat childhood obesity.
