No More King Size Candy bars!! NOOOOO!!!

Mars Inc., the candy giant that makes Snickers bars and M&M's, will stop selling products that have more than 250 calories per serving size as part of a new nutrition initiative, the Chicago Tribune reported Thursday.

That spells the end of the king-size Snickers bar, containing 510 calories -- though the company notes a serving size is only one-third of a bar. A regular-sized Snickers bar has 280 calories.
