Fans of king-sized candy bars, may wanna stock up now.
Candymaker Mars is trimming its chocolate bars after discussions with Michelle Obama's Partnership for a Healthier America.
CNN reports that the company plans to stop selling all chocolate bars with more than 250 calories by the end of 2013.
That means no more king-sized Snickers bars, which pack about 580 calories.
It also means some regular-sized candy bars will be a smaller.
The move is part of an agreement Mars signed and the Partnership for a Healthier America.
Mars is among 16 companies that have pledged to cut more than a trillion calories from their foods by the end of 2015.
