Mars Cutting King-Size Candy - ABC News Image Credit: Amazon Hungry? Starting in 2013 you'll have to grab a slightly smaller Snickers. Mars Inc., which makes M&Ms, Twix, MilkyWay and many other notable candies, told Reuters that by the end of next year it would not sell any chocolate products that had more than 250 calories. That means the more than 500 calorie "King Size" Snickers bar will become extinct, along with other "King Size" goodies. Mars told NPR the company planned to replace "King Size" candy with bags of smaller bars. According to NPR, the company said it wants to "enable sharing or saving a portion for later." Even the current 2-ounce Snickers is not small enough - it will have to downsize from 280 calories, losing at least 10 percent of its current self. On it's website, Mars talks about "responsible snacking" and highlights the fact that currently its "King Size" candy is made in two pieces, "one for now and one for later."
