From the shrinking size of Terry's Chocolate Orange to the change in spacing between Toblerone's triangular chunks, adjustments to the nation's favourite chocolate treats have been causing outrage this year.
So, for many people, the revelation that packets of Maltesers are now lighter than they used to be isn't welcome news.
This latest chocolate-related controversy was uncovered when Steve Dresser, a food retail expert, tweeted a picture of a pack of Maltesers advertised as containing 103g of chocolates.
However, as the signage in the photograph shows, the bags used to contain 121g, which means there has been a 15 per cent reduction in weight.
And it gets worse. Dresser also noticed a similar pack reduction in bags of Galaxy Counters, which have gone from 126g down to 112g.
Mars, who owns both chocolate brands, has declined to comment on the subject, but they aren't the only manufacturer to make changes to the size of their product.
Mondelez International, which increased the gap between the triangles in Toblerone bars last month, has assured consumers the cost-saving measure would have no impact on the taste of their famous confectionery.
"We will never compromise on taste nor our famous Swiss quality and can assure you that the Toblerone recipe hasn't changed," the brand said in a statement on its Facebook page.
Taste is definitely important, but when it comes to quantity, there's just one rule; no one likes eating less chocolate.
