mars bars are out
The regular 58 gram single bar contains 260 kilocalories.
In the second half of 2008, Mars UK reduced the size of regular bars from 62.5 g to the current 58 g. Although the reduction in size was not publicised at the time, Mars claimed the change was designed to help tackle the obesity crisis in the UK. The company later confirmed that the real reason for the change was triggered by rising costs.
In the UK, most Mars bars are still made at the Slough Trading Estate
